Latest Indian Ocean earthquake and tsunami Stories
“Sticking points” in the Earth’s tectonic plates caused by extinct undersea volcanoes could be responsible for producing tsunami earthquakes, a discovery which could lead to improved detection of these rare seismic events.
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.
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.
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.
In a report due for release tomorrow in the journal Nature, researchers from the University of Utah, the University of California, Santa Cruz, and seismologists from the United States Geological Service (USGS), contend that the massive April 11 earthquake, centered in the Indo-Australian plate, actually ripped at least 4 fault lines.
Why do some tsunamis, such as the devastating one that struck Japan in March 2011, occur on a much larger scale than scientists expect?
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.
