No tsunami threat to India due to Indonesia earthquake

There is no immediate tsunami threat to the Indian mainland and the Andaman and Nicobar Islands due to the earthquake which hit Indonesia today morning, the Indian government said.

"However, there is a possibility of a mild rise in the sea water level," the government said in a statement.

The union home ministry has advised the coastal states and union territories to take appropriate precautionary measures, it added.

Indonesia issued a tsunami warning after the 7.2-magnitude earthquake struck off the Sumatran coast of Aceh province.

DPA reports, quoting the Indonesian Meteorology, Geophysics and Climatology Agency, said the quake was recorded at 0559 GMT, with the epicentre 66 km southwest of Maulaboh in West Aceh district.

There were no reports of damage or casualties. (IANS)

Large Earthquake Hits Chile, Generates Tsunami Across Pacific

Tsunami warnings were issued for Hawaii, as well as Australia, New Zealand, Indonesia, Japan, and other countries along the Pacific coastline, as the giant waves triggered by the earthquake reverberated through the entire ocean.
This earthquake occurred at the boundary between the Nazca and South American tectonic plates. The two plates are converging at a rate of 80 mm per year. The earthquake occurred as thrust-faulting on the interface between the two plates, with the Nazca plate moving down and landward below the South American plate.
Coastal Chile has a history of very large earthquakes. Since 1973, there have been 13 events of magnitude 7.0 or greater. The February 27 shock originated about 230 km north of the source region of the magnitude 9.5 earthquake of May, 1960 -- the largest earthquake worldwide in the last 200 years or more. This giant earthquake spawned a tsunami that engulfed the Pacific Ocean. An estimated 1600 lives were lost to the 1960 earthquake and tsunami in Chile, and the 1960 tsunami took another 200 lives among Japan, Hawaii, and the Philippines.
Approximately 870 km to the north of the February 27 earthquake is the source region of the magnitude 8.5 earthquake of November, 1922. This great quake significantly impacted central Chile, killing several hundred people and causing severe property damage. The 1922 quake generated a 9-meter local tsunami that inundated the Chile coast near the town of Coquimbo; the tsunami also crossed the Pacific, washing away boats in Hilo harbor, Hawaii.
The magnitude 8.8 earthquake of February 27, 2010 ruptured the portion of the South American subduction zone separating these two massive historical earthquakes.
A large vigorous aftershock sequence can be expected from this earthquake.
