    Oh wait... I missed part of that, you're talking about the P and S waves going THROUGH the planet!

    they do and can be felt with seismic monitors (which is how we know about rocket launches in other countries for instance without seeing them with satellites). But I doubt the energy transferred through the earth would be very significant on the other side. You wouldn't feel it.

    Now if an asteroid hit one side and it's BIG enough, there is some evidence that the mechanical fracture would be transmitted to the far side (exactly opposite of the strike).

    Volcanoes Today, 7 Oct 2013: Fuego, Tangkubanparahu, Veniaminof, White Island, Copahue


    Tangkubanparahu (West Java): (6 Oct) Phreatic eruptions occurred from the crater on Saturday and Sunday morning (at 06.21 and 03:37 WIB, respectively). The eruptions lasted about 10 minutes and produced small ash plumes. Volcanologists measured strong tremor accompanying the eruptions.
    Access to the crater (a popular tourist spot in the vicinity of the regional capital Bandung) was closed within a radius of 1.5 km.


    White Island (New Zealand): The latest report of GNS/GeoNet comments on the recently increased tremor amplitude and mentions that a small steam eruption occurred on 4 October, but does not think a larger eruption is on its way.
    This is the full report:

    “Volcanic unrest continues at White Island (Whakāri). Volcanic tremor levels have remained slightly elevated since the eruption on 20 August. A further small energetic steam venting event occurred on 4 October around 4.30 pm. This generated a steam plume above the island that was seen from the mainland. The Volcanic Alert Level remains at 1 and the Aviation Colour Code at Green.

    Volcanic tremor levels have been elevated since about 24 September, but are at lower levels than those during eruptive activity during the January to April period this year.


    Veniaminof (Alaska Peninsula, USA): (6 Oct) The eruption of Veniaminof resumed this morning, the Alaska Volcano Observatory reports.
    “The Aviation Color Code has been increased to Orange and the Volcano Alert Level to Watch. Seismic tremor increased over the past several hours, and highly elevated surface temperature were observed in satellite images this morning. Lava effusion has likely resumed, but no ash emissions have been observed in satellite images. Web camera images are obscured by clouds. This is a similar level of eruptive activity that first began in June 2013.” (AVO)


    Fuego (Guatemala): In the past hours, activity has increased and might be heading towards another paroxysm. The frequency and size of explosions rose significantly and has been creating an ash plume about 1 km high and drifting 8 miles south and southwest. Many of the explosions generate shock waves, rattling roofs and windows of houses in the villages Panimaché, Morelia and Panimaché II.

    Constant degassing produces locomotive-like sounds and incandescent material ejected from strombolian activity reaches 125-200 m height and produces avalanches on the upper slopes. The lava effusion increased as well starting at 05:15 local time, and the flow towards Trinidad canyon reaches now 400 meters in length, generating avalanches. A second flow has started to move towards Ceniza canyon and avalanches from it reach 800 m length.


    Copahue (Chile/Argentina): Sporadic weak ash venting continues to be observed from time to time.

    The local press has commented on this, citing volcanologist Alberto Caselli that there is no associated change in seismic activity suggesting an impending new eruptive phase, but that the emissions are caused by decompression gas/steam release from a still hot, degassing magma body inside the inner conduits of the volcano. – Volcano Discovery

    I wonder if it's happened before?

    Probably. The Moon was created from part of the Earth. Supposedly created when we were hit with a rogue planetoid. If that's the case, it explains the Pacific Ocean's depths and the tectonic plates.

    Series Of At Least Six Earthquakes Rattle Mexico

    10/08/2013 ICA Leave a comment Go to comments


    AFP – “A series of at least six earthquakes — two reaching at least 5.0- magnitude — struck Sunday in the Mexican state of Guerrero, which is still reeling from deadly tropical storms last month.


    The epicenter of the strongest quake — 5.21-magnitude, at 9.27 local time (1527 GMT), according to the National Seismological Service — was located in the mountainous area where a September 16 mudslide buried a whole town.


    ‘We are monitoring the areas affected by the recent rains because the soil is moist and that can generate problems’ from the trembling, said Jose Luis Serna, civil protection director of the town nearest the epicenter, Coyuca de Benitez.


    ‘But so far, we have no news,’ he said.


    The quakes were also felt with moderate intensity in the resort town of Acapulco, which is recovering from the massive flooding brought on when storms Ingrid and Manuel swept across the country in mid-September.


    Authorities recommended moving ‘away from risk areas, such as slopes and where there are cracks in the ground,’ Guerrero governor Angel Aguirre said in his Twitter account.


    Tourists in Acapulco were evacuated from hotels to the Costera Miguel Aleman, the port town’s main tourist road.


    All six quakes were recorded between 9am local time (1500 GMT) and 10.36am (1636 GMT), and so far no damage has been reported in Guerrero state.” Source – The Borneo Post.

    Appears to have occurred on a coastline, population unknown. No big towns nearby though. And likely no tsunami...

    Hidden volcano beneath Yellowstone could wipe out human life across North America
    Sunday, December 15, 2013 by: Jonathan Benson, staff writer

    (NaturalNews) For all its beauty and wonder, Yellowstone National Park is hiding a colossal secret that could spell the end of humanity, at least on the North American continent. A massive "supervolcano" that scientists say could erupt at any moment sits beneath all those beautiful acres of forests, rocks, geysers and hot springs, ready to spew a volume of magma so immense that the entire American landscape could end up buried under several feet of it.

    At a recent meeting of the American Geophysical Union, scientists from the University of Utah made the case that Yellowstone's magma chamber is at least 250 percent larger than previously believed. According to the New York Post (NYP), the underground magma cavern beneath Yellowstone measures some 55 miles by 20 miles and contains untold billions of cubic meters of molten rock.

    "We've been working there for a long time, and we've always thought it would be bigger ... but this finding is astounding," stated University of Utah Professor Bob Smith to BBC News.

    Researchers for some time have been trying to pinpoint exactly what is going on underneath Yellowstone. And it is only due to a series of recent earthquakes that they were able to make considerable headway on the issue, verifying that there are literally hundreds of square miles of molten magma just waiting to burst from large cauldrons beneath the surface of the park.

    "The waves travel slower through hot and partially molten material," added Dr. Jamie Farrell about how earthquake tremors have enabled the improved mapping of underground activity. "With this, we can measure what's beneath."

    Yellowstone due for an eruption very soon based on historical data, say scientists
    While it has long been known that large pockets of volcanic magma are, indeed, present underneath Yellowstone, it is only in recent years that scientists have been able to determine whether or not this magma is an immediate threat. Based on the available evidence, they say, the infamous Yellowstone supervolcano is definitely due for an eruption.

    "From analysis of rock and sediment layers, scientists say another eruption is almost due -- at least by geological standards," writes James Seidel for the NYP. "Soil samples reveal that the last time it happened the whole of North America was smothered by ash. The lava flow was almost as great. The streams of molten rock were hundreds of miles long, and miles thick."

    Besides the historical data, things have literally been shaking up a whole lot more these days in and around the park. Just during the month of November, according to the U.S. Geological Survey (USGS), there were more than 300 earthquakes that shook the region around
    Yellowstone National Park, which could be indicative of an eruption in the not-too-distant future.

    "We know there's been these really large volcanic eruptions in the past and what we're seeing now matches that," stated Dr. Farrell to BBC News, noting that, when Yellowstone's supervolcano eventually erupts, the output will be about 2,000 times larger than that of Mount St. Helens when it erupted back in 1980.

    "These are really big volcanic eruptions and it would definitely be a global event," he added. "It would not only affect the U.S. but it would affect the world. All this material that is shot up in the atmosphere would eventually circle the earth and would affect the climate throughout the world."

    Bizarre Earthquake Lights Finally Explained

    Rare lights seen near earthquakes had long been called UFOs.

    The earthquake-damaged town of Onna in L'Aquila, Italy. Some residents saw bright lights before the earthquake struck the town in 2009.

    PHOTOGRAPH BY OLI SCARF, GETTY IMAGES


    Brian Clark Howard
    National Geographic
    Published January 6, 2014
    Rare flashes of light that are sometimes seen around earthquakes are not caused by birds, or planes, or UFOs—all of which had been previously used to explain the phenomena known as earthquake lights.
    Instead, the lights are caused by electrical properties of certain rocks in specific settings, report scientists in a new paper.
    Sometimes called earthquake lightning, the lights can take "many different shapes, forms, and colors," says study coauthor Friedemann Freund, an adjunct professor of physics at San Jose State University and a senior researcher at NASA's Ames Research Center.
    Freund says common forms of earthquake lights include bluish flames that appear to come out of the ground at ankle height; orbs of light called ball lightning that float in the air for tens of seconds or even minutes; and quick flashes of bright light that resemble regular lightning strikes, except they come out of the ground instead of the sky and can stretch up to 650 feet (200 meters).
    Historic Sightings
    Over the centuries, there have been many reports of earthquake lights, both before and while the ground is shaking.
    Just seconds before the 2009 L'Aquila, Italy, earthquake, people saw four-inch (ten-centimeter) flames of light flickering above a stone street.
    On November 12, 1988, people reported a bright purple-pink globe of light along the St. Lawrence River in Quebec, 11 days before a powerful quake.
    People also reported seeing a faint rainbow of light before the great 1906 quake in San Francisco and lights before the devastating 1811-12 New Madrid earthquakes in Missouri.
    Freund and colleagues studied such historic accounts going all the way back to the year 1600 and published their findings in Seismological Research Letters.
    UFO Fodder
    "In the past, people often interpreted [earthquake lights] in religious terms, and in modern times they thought of UFOs, although there is a completely rational physical explanation that we are working on," Freud says.
    Jim Conacher thought he was seeing UFOs when he spied seven yellow, luminous globes floating on a mountain on Tagish Lake in Canada's Yukon territory in the early 1970s.
    A retired Canadian government agriculture inspector, Conacher took a photo of the lights, which circulated widely as purported evidence of a UFO encounter.
    Photograph by Jim Conacher
    Earthquake lights are captured in this photo taken at Tagish Lake, in the Yukon Territory, in 1972

    Freund and colleagues noticed that the timing of Conacher's photo seemed to place it just a few hours before the nearby Cross Sound earthquake of July 1, 1973, which measured 6.7 on the Richter scale.
    For many years, sightings of earthquake lights were dismissed by the serious geology community.
    But in the mid-1960s, during a series of earthquakes in Nagano, Japan, scientists made photos of earthquake lights that were clearly tied to the geologic activity. Since then, an increasing number of the phenomena have been captured on film and video, Freund said, in part because of the rise of surveillance cameras.
    For example, cameras caught clear images of earthquake lights in Pisco, Peru, in August 2007, during a magnitude 8 earthquake there.
    How Earthquake Lights Form
    Over the past few years, various theories have been proposed for how earthquake lights form, including the disruption of the Earth's magnetic field by tectonic stress and the so-called piezoelectric effect, in which quartz-bearing rocks produce voltages when compressed in a certain way.
    But Freund and colleagues now report that what causes earthquake lights appears to be an entirely different electrical process.
    "When nature stresses certain rocks, electric charges are activated, as if you switched on a battery in the Earth's crust," he says.
    The types of rocks that are particularly given to the phenomenon are basalts and gabbros, which have tiny defects in their crystals. When a seismic wave hits, electrical charges in the rocks may be released.
    In some areas, basalts and gabbros are present in vertical structures called dikes, which formed as magma cooled along vertical faults and may reach as deep as 60 miles (97 kilometers) underground. These dikes may funnel electrical charges along, the scientists wrote.
    "The charges can combine and form a kind of plasma-like state, which can travel at very high velocities and burst out at the surface to make electric discharges in the air," Freund added. Those discharges are what make the colorful light shows.
    The right conditions for lights exist in less than 0.5 percent of earthquakes worldwide, the scientists estimate, which explains why the phenomena are relatively rare.
    Earthquake lights seem to be most common in Italy, Greece, France, Germany, China, and parts of South America, though they have been observed in Japan, North America, and elsewhere.
    The lights can occur weeks before major earthquakes, Freund noted, or during actual shaking. They have been recorded at distances of up to 100 miles (160 kilometers) from the epicenter.
    Predicting Earthquakes?
    Freund is working with other scientists on a global earthquake forecasting system and says scientists have started including earthquake lights as an indicator that a tremblor might be coming. (He avoids the term "prediction" because "it implies too much precision.")
    "If we see two, three, or four characteristic phenomena, then it looks like there might be an earthquake," he said. He admitted that earthquake lights tend to be rare, but added, "If they are observed, let's watch out."
    But others say that the lights will be of limited use for such forecasts.
    "Earthquake lights are unlikely to be very helpful with earthquake prediction because they don't seem to be reported all that often," says Bruce Presgrave, a geophysicist with the U.S. Geological Survey's National Earthquake Information Center.
    Earthquake lights have already been used to help predict quakes. Just before Italy's L'Aquila earthquake in 2009, a man in his kitchen saw bright flashes of light. Because he had reportedly read about earthquake lights before, he moved his family to a safer place.
    In China in 1976, a geologist took shelter after seeing lights, which were followed by the deadly Tangshan quake.
    Still, Freund says the lights are a small part of his broader work involving the electrical conductivity of rocks.
    "I wasn't interested in earthquakes in the beginning, but then I realized that electrical phenomena are being activated by stress in the rocks," he says. "Earthquake lights are the tip of the iceberg, the most extreme expression of these phenomena, but underneath there are lots of other aspects, and we are considering measuring these in the context of forecasting."
    As a next step, Freund hopes to reproduce earthquake lights in a laboratory. He also wants to better understand what causes the outburst of energy that leads to visible light.

    Magnitude-8.2 Quake Strikes Northern Chile

    April 1, 2014

    A powerful magnitude-8.2 earthquake struck off Chile's northern coast Tuesday night, causing landslides and setting off a tsunami that forced an evacuation of coastal areas. There were no immediate reports of injuries or major damage, but buildings shook in nearby Peru and in Bolivia's high altitude capital of La Paz.

    The U.S. Geological Survey initially reported the quake at 8.0, but later upgraded the magnitude. It said the quake struck 61 miles (99 kilometers) northwest of the Chilean city of Iquique at 8:46 p.m., hitting a region that has been rocked by numerous quakes over the past two weeks. Aftershocks followed, including a magnitude-6.2 tremor and a 5.5 quake.

    Coastal residents of northern Chile evacuated calmly as waves measuring almost 2 meters (6 1/2 feet) struck ahead of a tsunami that was expected to come ashore later. The Pacific Tsunami Warning Center issued an alert for all of Latin America's Pacific coast. Chile's Emergency Office said a large tsunami wave was expected to hit Robinson Crusoe island and others in the Juan Fernandez archipelago just before midnight local time.

    Chile's emergency service reported some roads blocked by landslides caused by the quake, but said no injuries had been reported so far.

    An official at Peru's civil defense office said evacuations were underway on that country's coast. The official, who did not give her name, said there were no immediate reports of damage. Police officer Alejandro Rosado in a Tacna, a Peruvian town near the coast, said no damage or injuries had been reported there.

    Chile is one of the world's most earthquake-prone countries. A magnitude-8.8 quake and ensuing tsunami in central Chile in 2010 killed more than 500 people, destroyed 220,000 homes, and washed away docks, riverfronts and seaside resorts.

    The strongest earthquake ever recorded on Earth also happened in Chile - a magnitude-9.5 tremor in 1960 that killed more than 5,000 people.

    Hundreds of earthquakes have shaken Chile's far-northern coast in the past two weeks, keeping people on edge as scientists said there was no way to tell if the unusual string of tremors was a harbinger of an impending disaster.

    The unnerving activity began with a strong magnitude-6.7 quake on March 16 that caused more than 100,000 people to briefly evacuate low-lying areas, although no tsunami materialized and there was little physical damage from the shaking.

    Peru Volcano Erupts After 40 Years: 4 Fast Facts About Mount Ubinas' Eruption

    April 2, 2014

    Peru's Ubinas volcano, which has not erupted in forty years, erupted on Tuesday after months of activity. Authorities evacuated villagers to keep them safe from Ubinas' destruction.

    Located in southwestern Peru, the Ubinas volcano erupted at 7:42 a.m. and emitted ash for one thousand meters, according to Orlando Macedo, the director of the Geophysical Institute of Arequipa. Peru's geological and mining agency (Ingemmet) has revealed that the volcano became active in September of 2013 and lava had been building up over the past few weeks. El Comercio reports that the Peruvian Geophysical Institute has observed changes in the physical shape of the crater.

    Ubinas town mayor, Pascual Coaquira, has revealed that 60 villagers in the village of Querapi, which is located 5 kilometers from the volcano's base, were relocated on Saturday. The people of Querapi are slated to permanently shift from their village to Pampas de Hawái; the decision was revealed after Ubinas became active last September, as preliminary explosions emitted silicon ash resulting in respiratory and gastrointestinal irritation in people.

    "We are readying a shelter for refugees from the blasts," said the mayor. "The volcano has been emitting a lot of ash all day, the people in the town (of Ubinas) are having some problems breathing."

    The Ubinas volcano is considered to be the most active volcano in Peru, with recorded eruptions dating back to 1550. In the greater Moquegua area, there are said to be roughly 40 dormant volcanoes.

    WYOMING – An animal exodus at Yellowstone National Park in Wyoming has residents and tourist wondering if they know something they don’t.
    Bison and many other animals are leaving Yellowstone in droves, and its prompting theories that minor earthquakes in the area could soon set off the Yellowstone Super Volcano.


    A series of smaller quakes have hit the region over the past few weeks, and the more earthquakes hit an area, the more chances a volcano may be activated from its dormant state.

    Videos of bison seemingly fleeing Yellowstone National Park in Wyoming have sparked concerns among some bloggers that recent seismic activity could trigger the eruption of the park’s so-called supervolcano.


    According to Epoch Times, multiple videos of such incidents have been posted online recently, one of which shows a herd of buffalo allegedly leaving the park and “running for their lives.” Although people behind the discussion acknowledge there’s no way to predict when the park’s massive volcano could erupt, they believe the reaction of the Yellowstone’s animals could signal some kind of alert.


    On March 30, Yellowstone was struck by the most powerful earthquake it has experienced since 1980 – a 4.8 magnitude quake that did no damage, but that some believe could be connected to the various animals’ movements.



    “Whether I believe this, or whether I don’t believe the story or not, I don’t know. I can tell you this story I saw this morning about the buffaloes running the street …
    whether or not it’s because of any activity in Yellowstone or not, I don’t know,”
    said blogger Jay Lee, according to the Times.


    But I’ll tell you this, whatever the case may be, that their running away from Yellowstone is an alert of some sort.”


    Another video uploaded to YouTube, this time by self-described “survivalist” and “search-and-rescue expert” Tom Lupshu, claims, “Biologists aren’t sure if there’s been a stunning decline in the herd or if other factors have skewed the tally.” Lupshu also said that helium releases in the area are 1,000 times above normal levels, and accused the US Geological Survey of not reporting small quakes occurring near the volcano.


    Herds of bison running for their lives on the public roadways and they were not being chased or rounded up, the bison were running down the mountain slopes onto roadways running right past a filming crew,” he added. “They detect something vast and deadly. The Yellowstone Supervolcano is the only thing there that would fit the bill.”



    The supervolcano – which was found last year to be 2.5 times larger than previously thought – has not erupted in over 640,000 years, leaving some to speculate that a blast is overdue. If and when it erupts again, the volcano could potentially spew ash over large swathes of North America and cause trouble around the entire planet.


    "It would be a global event," Jamie Farrell of the University of Utah told the Associated Press last year. "There would be a lot of destruction and a lot of impacts around the globe."


    Although Farrell said scientists don’t know enough to map out the next eruption’s likely arrival, he did say they’d know if magma was moving towards the Earth’s surface.
    In another video, Lupshu said that increased seismic activity at Yellowstone could bring about the volcano’s eruption, but the Geological Survey has noted such activity is currently par for the course, and that between 1,000 and 3,000 earthquakes hit the area every year. The agency also stated that helium releases have “no implications about volcanic hazards.”


    According to Epoch Times, the University of Utah Seismograph Stations also downplayed fears.


    There is no evidence that a catastrophic eruption at Yellowstone National Park (YNP) is imminent,” the service said. “Current geologic activity at Yellowstone has remained relatively constant since earth scientists first started monitoring some 30 years ago. Though another caldera-forming eruption is theoretically possible, it is very unlikely to occur in the next thousand or even 10,000 years.”

    I believe we're coming up to an "event".... in Yellowstone. Perhaps not the "big one", but something BIG ENOUGH to make animals flee the park.

    Reports bison ‘fleeing’ Yellowstone amid fears quake could trigger eruption of park’s supervolcano

    DO they know something we don’t? Reports of animals fleeing Yellowstone has sparked concerns that the park’s supervolcano may be set to blow.




    Yellowstone National Park was hit by a 4.8-magnitude earthquake on March 30, prompting fears it could trigger a cataclysmic eruption that would cover North America in ash.


    The quake was the largest in the park since 1980, and part of a series of foreshocks and aftershocks that rattled the famous park.


    Bloggers and survivalists have posted videos online they say show the park’s bison “running for their lives”, reports The Epoch Times.

    Yellowstone National Park sits atop the Yellowstone Caldera, the crater of a massive supervolcano. The park attracts millions of visitors each year to its famous geysers and hot springs, powered by the hot lava below.


    In recent years, scientists discovered the caldera is 48 kilometres wide — far larger than previously thought.


    Worried blogger Jay Lee posted video of a herd of bison he says were “running for their lives” down a Yellowstone road, and warns humans should take notice.

    Bison Running in Yellowstone

    While conceding the animals could be running from hunters or other reasons, he says: “But I’ll tell you this, whatever the case may be, that their running away from Yellowstone is an alert of some sort.”


    Ohio survivalist Tom Lupshu said the bison count for Yellowstone is down 25 per cent this northern winter, suggesting animals may be leaving the park because they sense an impending catastrophic volcanic eruption triggered by recent earthquakes.


    “They detect something vast and deadly,” says Mr Lupshu of the wildlife on YouTube.


    “The Yellowstone Super volcano is the only thing there that would fit the bill,” he says.


    The Yellowstone super volcano has had three cataclysmic eruptions — 2 million, 1.3 million and 640,000 years ago, creating a series of ‘nesting’ calderas, say scientists.


    The eruption 2 million years ago was the most catastrophic, covering half of North America with ash and wiping out prehistoric animals, reports the Yellowstone Volcano Observatory.

    While scientists predict it will erupt again, they say it won’t happen anytime soon, reports EarthSky.


    “Yellowstone is one of the biggest super volcanoes in the world,” said University of Oregon geologist Ilya Bindeman.
    The inevitable next ‘big one’ will wipe out the surroundings for hundreds of kilometres, covering the US and Canada in ash, he told EarthSky. It would devastate agriculture and cause global cooling for a decade, he says.


    A volcanic eruption of that size “hasn’t happened in modern civilisation,” he said.


    However, the US Geological Survey downplayed risk of Yellowstone Caldera erupting, saying the park gets thousands of earthquakes every year, and that helium emissions do not indicate an impending eruption.
