Latest Earthquake Stories
A powerful 7.3 magnitude earthquake struck off the coast of El Salvador Sunday night, followed by a 5.4 magnitude aftershock an hour later, according to a report by the US Geological Survey.
A swarm of moderately-sized earthquakes struck Imperial County, north of El Centro, California late Sunday morning and early Sunday afternoon, according to the US Geological Survey.
Why do some tsunamis, such as the devastating one that struck Japan in March 2011, occur on a much larger scale than scientists expect?
Glacierologists said their recent study not only provides a window into the behavior of glaciers—it also could be used as a simple model for the mechanism behind slip-stick earthquakes.
Over the last 50 million years, the Caribbean islands have been pushed east, driven by the movement of the Earth's viscous mantel against the more rooted South American continent.
A new study by researchers at Durham University in the United Kingdom asserts that landslide deaths have been underestimated by tenfold.
A team of researchers may have discovered a way to hear earthquakes.
The press release and paper noted below, publishing in the Bulletin of the Seismological Society of America, is strictly under embargo until 12:00 Noon Eastern Time US on August 2, 2012.
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.
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...
