Earthquake Sounds Help Predict Tsunamis

According to a new report, two researchers have identified key acoustic characteristics of the 2011 Japan earthquake that could be used to significantly improve tsunami warning systems.

'Caldas Tear' Resolves Seismic Activity Beneath Colombia

Colombia sits atop a complex geological area where three tectonic plates are interacting, producing seismicity patterns that have puzzled seismologists for years.

Slow Earthquakes On San Andreas Fault Explained

New Zealand’s geologic hazards agency reported this week an ongoing, “silent” earthquake that began in January is still going strong. Though it is releasing the energy equivalent of a 7.0 earthquake, New Zealanders can’t feel it because its energy is being released over a long period of time, therefore slow, rather than a few short seconds.

Slow Earthquakes Take Weeks To Occur

Researchers have been aware of slow earthquakes for only the past decade, but little has been understood about them. However, new tools may help explain what triggers these quakes.

Researchers have shown that, by using global positioning systems (GPS) to measure ground deformation caused by a large underwater earthquake, they can provide accurate warning of the resulting tsunami in just a few minutes after the earthquake onset.

Fossils Help Researchers Learn More About Cascadia Quake Of 1700
2013-05-15 18:17:53

Scientists have long been baffled by a massive earthquake that struck the western coast of North America in 1700.

Arabian Sea Earthquake Risk Predictions Were Underestimated
2013-05-13 16:04:27

Researchers writing in the journal Geophysical Research Letters say the western Indian Ocean earthquake and tsunami hazard potential is greater than scientists had originally predicted.

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...
