Latest Earthquake Stories
Fracking and injection wells are causing earthquakes around gas fields across the United States. This is a fact. Is it from waste-water injection wells or the production of gas? Geologists are not sure.
Exploring Tokyo: One year after the earthquake, tsunami and partial meltdown, Japan's tourism is up.
Things could get shaky as scientists will gather in San Diego next week to present their latest seismological research at the annual conference of the Seismological Society of America (SSA).
Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to understanding plate ruptures and predicting eruptions—both of which are important steps for protecting the public from earthquake and volcanic hazards.
Wednesday’s powerful 8.6-magnitude earthquake that struck off Indonesia’s western coast at 2:38 p.m. local time, was followed by fears of a tsunami, gripping a region that still had the 2004 tsunami -- one that ravaged numerous coastal communities along the Indian Ocean and killing more than 230,000 people -- fresh in their minds.
A tsunami warning has been issued for the entire Indian Ocean on Wednesday April 11 after a massive 8.7 magnitude earthquake off the coast of Indonesia at 2:38 p.m. local time (3:38 a.m. EST) sent residents around the region out of their homes and offices in fear.
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.
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...
