Latest Earthquake Stories
A new study evaluates the seismic hazards for the entire Central America, including specific assessments for six capital cities, with the greatest hazard expected for Guatemala City and San Salvador, followed by Managua and San José, and notably lower in Tegucigalpa and Panamá City.
The San Jacinto Fault (SJF) Zone is a seismically active, major component of the overall southern San Andreas Fault system.
Highlights include several studies based in the U.S. Sierra Nevada, including a description of "magma fingers" and the formation of granite in the high Sierra crest near Yosemite National Park.
World leaders, scientists, and members of the media are among those pausing this weekend to reflect on the one-year anniversary of the 9.0 magnitude earthquake that struck Japan on March 11, 2011 and, combined with the ensuing tsunami, caused widespread death and destruction throughout the country.
On the one-year anniversary of the devastating Japanese tsunami, engineers from the USC Viterbi School of Engineering Tsunami Research Center are working with the State of California to better understand the damaging currents caused by tsunamis.
A scientist has converted last year's 9.0-magnitude Tohoku-Oki, Japan earthquake's seismic waves into audio files to allow researchers to "hear" what the quake sounded like as it moved through the earth.
One year on from the magnitude-9.0 earthquake that unleashed a devastating tsunami and caused a partial meltdown of the Fukushima Daiichi nuclear plant, this month's special issue of Physics World, on the theme of "Physics and the Earth", includes an investigation by journalist Edwin Cartlidge into the latest advances in earthquake forecasting.
Yulee, Florida. Not a place one usually thinks of as an Earthquake Epicenter. But this swampland not far from the Georgia state line is now home to a state-of-the-art seismic station known as 457A.
Seismic risk at the Fukushima nuclear plant increased after the magnitude 9 earthquake that hit Japan last March, scientists report.
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...
