Latest Earthquake Stories
Changes in seismic velocity--changes in the speeds at which seismic waves move through the Earth's crust--have been identified during and after many earthquakes.
A comprehensive analysis of the Cascadia Subduction Zone off the Pacific Northwest coast confirms that the region has had numerous earthquakes over the past 10,000 years, and suggests that the southern Oregon coast may be most vulnerable based on recurrence frequency.
Researchers from Washington University in St. Louis, Missouri have found that giant ice avalanches on Saturn's moon Iapetus could provide clues to slippage in other places in the Solar System.
Caltech researchers provide highest-resolution observations yet of the complex 2012 Sumatra earthquake
Although the earth is shaken by approximately 80,000 earthquakes every month, not many of them will send you running for the nearest doorway. However, scientists, led by a team at Karlsruhe Institute of Technology (KIT) in Germany, have recently started investing more time and research into understanding these subtle vibrations that occur deep in the Earth’s crust.
Scientists at UC Santa Barbara have accumulated the first evidence-based inclusive study of the probability for tsunamis in Northwestern California.
Using data supplied by a mobile operator, researchers at Karolinska Institutet have shown that population movements after the 2010 Haiti earthquake followed regular patterns.
The National Research Council folded to pressure from the fossil fuel industry and pro-fracking Congress members last week by releasing a “more study needed” report on fracking and earthquakes.
Global seismic hazard maps exist to help societies and decision-makers anticipate and prepare for earthquakes.
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...
