Japan's recent magnitude 9.0 earthquake, which triggered a devastating tsunami, relieved stress along part of the quake fault but also has contributed to the buildup of stress in other areas, putting some of the country at risk for up to years of sizeable aftershocks and perhaps new main shocks, scientists say. After studying data from Japan's extensive seismic network, researchers from the Woods Hole Oceanographic Institution (WHOI), Kyoto University and the U.S. Geological Survey (USGS)...

By Louis Bergeron, Stanford The magnitude 9 earthquake and resulting tsunami that struck Japan on March 11 were like a one-two punch "“ first violently shaking, then swamping the islands "“ causing tens of thousands of deaths and hundreds of billions of dollars in damage. Now Stanford researchers have discovered the catastrophe was caused by a sequence of unusual geologic events never before seen so clearly. "It was not appreciated before this earthquake that this size of...

Earthquake scientists trying to unravel the mysteries of an unfelt, weeks-long seismic phenomenon called episodic tremor and slip have discovered a strange twist. The tremor can suddenly reverse direction and travel back through areas of the fault that it had ruptured in preceding days, and do so 20 to 40 times faster than the original fault rupture. "Regular tremor and slip goes through an area fairly slowly, breaking it. Then once it's broken and weakened an area of the fault, it can...

A magnitude 5.2 earthquake in Lorca, Spain has killed eight people and left many more injured. A magnitude five earthquake occurs somewhere in the world about three times a day, but Spain's buildings are not generally constructed to protect against quakes. The Murcia region is the most seismically active in Spain, and some of the medieval buildings were badly damaged during the 5.2 earthquake. This event occurred at just six miles below the Earth's surface. Roger Musson from the British...

Bolivia may need to prepare for a possible 8.9 magnitude quake that would be 125 times more powerful than previously calculated to be possible in this area, AFP reports. Two million people in the region of the east of the central Andes mountains could be affected in what had been thought, until now, to be a relatively calm area for seismic activity, according to a study published in Nature Geoscience. "No one suspected that the previous estimates were too low," Benjamin Brooks, a...

Advanced computation enabled by supercomputers enhances understanding of earthquake and tsunamis and their impacts Summary: Earthquake and tsunami. March 11, 2011. Japan. More than 26,000 people are dead or missing and an estimated 400,000 are homeless. An estimated 25 trillion yen, or $330 billion dollars, in damages make it the most costly natural disaster on record. The estimates are more than three times those of the second most costly natural disaster, also an earthquake in Japan. The...

TACOMA, Wash., April 25, 2011 /PRNewswire/ -- When the next major earthquake hits this region, a substantial amount of buildings and schools are likely to sustain major damage and, in many cases, even collapse. But thanks to a new line of desks that serve as protective armor, a lot of the folks inside these buildings are now more likely to survive. - Robert von Bereghy, founder of LifeGuard Structures, WHO: maker of new earthquake-proof desks and...

The massive subduction zone earthquake in Japan caused a significant level of soil "liquefaction" that has surprised researchers with its widespread severity, a new analysis shows. The findings also raise questions about whether existing building codes and engineering technologies are adequately accounting for this phenomenon in other vulnerable locations, which in the U.S. include Portland, Ore., parts of the Willamette Valley and other areas of Oregon, Washington and California. A...

Pacific Ring of Fire
2013-02-19 13:18:27

The Pacific Ring of Fire, or Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 25,000 mile horseshoe shape, it’s associated with an almost continuous series of oceanic trenches, volcanic belts, volcanic arcs and/or plate movement. The Ring of Fire contains 452 volcanoes and is home to over 75 percent of the world’s active and dormant volcanoes. It’s sometimes called the circum-Pacific belt or the...

The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a particular type of seismometer. A earthquake measuring 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The moment magnitude, calibrated to give generally similar value for medium-sized...
