The entire world becomes an aftershock zone after a massive magnitude (M) 7 or larger earthquake—but what hazard does this pose around the planet?

Superstorm Sandy Made A Seismic Impact, Shaking Up North America

There’s no doubt that last autumn’s superstorm Sandy left a trail of destruction as it churned up the eastern seaboard, making a bulls-eye run at New York City. But a new study from researchers at the University of Utah has found that the storm also shook things up a bit.

Seismic Ocean Surveys For Gas And Oil Could Kill 140,000 Marine Mammals

Blasting sound waves through the ocean to the seafloor in search of fossil fuels may do more harm than good, according to environmentalists. But the US Department of Interior has been considering giving large oil and gas companies permission to do just that.

Salt Lake Valley, home to the Salt Lake City segment of the Wasatch fault zone and the West Valley fault zone, has been the site of repeated surface-faulting earthquakes (of about magnitude 6.5 to 7).

Earth Is Lazy, Say Geoscientists

Geoscientists have taken an uncommon approach to modeling the development of fault lines in the Earth’s crust, and their so-called "Earth is lazy" approach is providing new insights into how these faults grow.

Scientists Solve Mystery Of California Tectonics

Two years ago today, Japan was rocked by a 9.0-magnitude earthquake and giant tsunami that caused both death and destruction throughout the country. Now, with instrument's like the European Space Agency's GOCE satellite, scientists will be able to understand a bit more about these devastating quakes.

Waves Generated By Russian Meteor Recorded Crossing The US

A network of seismographic stations recorded spectacular signals from the blast waves of the meteor that landed near Chelyabinsk, Russia, as the waves crossed the United States.

When Tsunamis Break All The Rules
2013-03-07 05:04:34

An international collaboration has resulted in a new study showing that the earthquake zones off certain coasts, such as Japan and Java, make them especially vulnerable to tsunamis.

Pacific Ring of Fire
2013-02-19 13:18:27

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...
