Kelly Brunt, a cryosphere specialist at Goddard Space Flight Center, Greenbelt, Md., and colleagues were able to link the calving of icebergs from the Sulzberger Ice Shelf in Antarctica following the Tohoku Tsunami, which originated with an earthquake off the coast of Japan in March 2011. The largest earthquakes on Earth occur at the interface between the two plates, called the megathrust. List of recent and latest earthquakes recorded in and close to this area today and now.

The largest recorded earthquake in the world was a magnitude 9.5 (Mw) in Chile on May 22, 1960. Now glaciologists have discovered that it's also creating earthquakes as it breaks up. Recently, scientists installed 13 weather-resistant seismic stations on the continent that measured the speed of earthquake waves through underlying bedrock and mantle. The Maule earthquake was the sixth largest ever recorded, and it was relatively close to Antarctica. Waves generated by the massive March 2011 undersea earthquake off Japan chopped huge chunks of ice off the Sulzberger Ice Shelf in Antarctica. Dozens of earthquakes have been registered just south of the King George Island, South Shetland Islands, Antarctica over the past 30 days, with magnitudes ranging from 4.7 to 6.0. M 9.5 - 1960 Great Chilean Earthquake (Valdivia Earthquake) The 8 Most Powerful Earthquakes Ever Recorded But the survey revealed that East Antarctica was not a seismic anomaly after all.

Strasbourg (AFP) Dec 23, 2004 - A massive earthquake measuring 8.2 on the Richter scale struck the largely uninhabited area around Macquarie Island in Antarctica, south of New Zealand and Tasmania, early Friday, French seismological officials said. THE world's biggest earthquake in almost four years has struck 800km off the coast of Tasmania, Australian seismological officials said. How far away can a 9.0 earthquake be felt? Macquarie Island station leader, Graeme Beech, said the first he knew of the earthquake was when he received a warning from the Pacific Tsunami Warning Centre this morning. “Because Antarctica is so far from Chile, the seismic waves were weak and the changes to the stress in the ice sheet small,” Wiens said. Sources It is Japan's largest quake, but dating back to 1900, four other earthquakes of magnitude 9.0 or greater have ruptured across the globe, according to data from the U.S. Geological Survey (USGS).

Human habitation of King George Island is limited to research stations. The largest earthquake ever recorded by seismic instruments anywhere on the earth was a magnitude 9.5 earthquake in Chile on May 22, 1960. The earthquake, which occurred half-way between Australia and Antarctica, was felt throughout Tasmania. Recent examples include the magnitude 8.8 earthquake in Chile in February 2010 and the magnitude 9.1 earthquake offshore Sumatra in December 2004; the latter triggered a devastating tsunami. Its usefulness is that at a glance, you can see how the restless planet Earth is shaking. In general, though, Antarctica is seismically quiet. It originated from the Ross Ice Shelf in Antarctica, and was a whopping 170 miles (270 kilometers) long and 25 miles (40 km) wide – nearly the size of Connecticut, larger than the island of Jamaica.Over time, the iceberg broke into smaller pieces, according to Live Science, which can still be seen around the virtually uninhabited ice-covered landmass. At 11,000 square kilometers, an iceberg that broke off Antarctica is the world’s largest iceberg that is bigger than whole of Jamaica. Tsunamis are large, long period waves of water that may impact coastal areas reaching several tens of metres in height. In March 2011, Japan's Tohoku tsunami tore off two Manhattan-size icebergs from the … It’s the biggest Earthquake to ever been recorded in North-America and with a magnitude of 9.2 it’s the second biggest earthquake to have ever been recorded worldwide. [ 1997] are also shown. Because of its depth, no damage was reported, but small tsunami waves were observed.

Antarctica yields oldest fossils of giant birds with 21-foot wingspans: Two fossils from a group of extinct seabirds represent the largest individuals ever found. “This might be the perfect storm of an event, that hit the ice shelf like a gong,” Bassis says. Interestingly enough though, deep focus earthquakes can occur at depths of hundreds of miles and can be felt literally half a world away. The earthquakes ranged in size from magnitude 2.1 to 3.9, making them minor events. In October, 1989, the Loma Prieta earthquake hit San Francisco, causing total economic damage of $5.6 billion dollars. Earthquakes and Tsunamis.
