Latest Earthquake Stories
A magnitude 7.3 earthquake struck off the coast at 5:18 p.m. local time Friday evening triggering a small 3-foot-high tsunami that swept against the Japanese mainland nearly 45 minutes later.
Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have typically been generated by earthquakes or man-made explosions.
Scientists at the American Geophysical Union meeting in San Francisco this week reported that the Himalayas and Pacific Northwest could experience major earthquakes.
The Soviet government has long kept outsiders away from the Russian Far East, shrouding a source of powerful earthquakes and volcanic activity on the Pacific Rim in secrecy.
Enjoying Spanish participation, an international group of researchers have analyzed the most recent history of the Alhama de Murcia fault.
The 2011 Mineral, Virginia M-5.8 earthquake was felt over an extraordinarily large area.
The more time it takes for an earthquake fault to heal, the faster the shake it will produce when it finally ruptures, according to a new study by engineers at the University of California, Berkeley, who conducted their work using a tabletop model of a quake fault.
Scientists have found evidence of a deadly tsunami that inundated coastal Switzerland in AD 563 after a rockfall near the River Rhone swept Lake Geneva.
The scientific community has largely dismissed weather-driven earthquakes as myths or relics of an earlier, more mystical society.
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...
