Earthquake that will trigger a Tsunami (2008-2012)


The Sumatra quake in 2004 has increased the probability of similar earthquake under the sea. The impact of a probable earthquake will be more in coast of India than the 2004 quake. The above is the map shoing the probability of the epicentre of the quake in the sea. Red spots are the active volcanos.

Study of Volatile Earthquake Zone

Deep-sea Scientific Drilling Program To Study Volatile Earthquake Zone Launched - Source: Science Daily

The Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) gets underway September 21, with the Japanese drilling vessel Chikyu departing from Shingu Port with scientists aboard, all ready to log, drill, sample, and install monitoring instrumentation in one of the most active earthquake zones on Earth.

Tsunami Warning issued to Andaman and Nicobar

TSUNAMI BULLETIN NUMBER 001PACIFIC TSUNAMI WARNING CENTER/NOAA/NWSISSUED AT 1124Z 12 SEP 2007THIS BULLETIN IS FOR ALL AREAS OF THE INDIAN OCEAN.... AN INDIAN-OCEAN-WIDE TSUNAMI WATCH IS IN EFFECT ...A TSUNAMI WATCH IS IN EFFECT FOR INDONESIA / AUSTRALIA / INDIA / SRI LANKA / THAILAND / UNITED KINGDOM / MALDIVES / MYANMAR / MALAYSIA / BANGLADESH / MAURITIUS / REUNION / SEYCHELLES / MADAGASCAR / SOMALIA / OMAN / PAKISTAN / IRAN / YEMEN / COMORES / CROZET ISLANDS / MOZAMBIQUE / KENYA / TANZANIA / KERGUELEN ISLANDS / SOUTH AFRICA / SINGAPORE THIS BULLETIN IS ISSUED AS ADVICE TO GOVERNMENT AGENCIES. ONLYNATIONAL AND LOCAL GOVERNMENT AGENCIES HAVE THE AUTHORITY TO MAKEDECISIONS REGARDING THE OFFICIAL STATE OF ALERT IN THEIR AREA ANDANY ACTIONS TO BE TAKEN IN RESPONSE.AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS ORIGIN TIME - 1110Z 12 SEP 2007 COORDINATES - 4.5 SOUTH 101.3 EAST LOCATION - SOUTHERN SUMATERA INDONESIA MAGNITUDE - 7.9EVALUATION EARTHQUAKES OF THIS SIZE HAVE THE POTENTIAL TO GENERATE A WIDESPREAD DESTRUCTIVE TSUNAMI THAT CAN AFFECT COASTLINES ACROSS THE ENTIRE INDIAN OCEAN BASIN. HOWEVER - IT IS NOT KNOWN THAT A TSUNAMI WAS GENERATED. THIS WATCH IS BASED ONLY ON THE EARTHQUAKE EVALUATION. AUTHORITIES IN THE REGION SHOULD TAKE APPROPRIATE ACTION IN RESPONSE TO THE POSSIBILITY OF A WIDESPREAD DESTRUCTIVE TSUNAMI.

DUE TO ONLY LIMITED SEA LEVEL DATA FROM THE REGION IT MAY NOT BE POSSIBLE FOR THIS CENTER TO RAPIDLY CONFIRM NOR EVALUATE THE STRENGTH OF A TSUNAMI IF ONE HAS BEEN GENERATED.ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTSWITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUALARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THELARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEENSUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.

Another Tsunami likely our generation is going to experience

NEW DELHI: Millions of people living on the Bay of Bengal coast face a tsunami, possibly as devastating as the one in 2004 which killed more than 200,000 people when a 9.3 magnitude earthquake triggered it off Sumatra. Renowned geologist from Geoscience Australia, Phil R Cummins, known to have also predicted the 2004 tsunami, however, claimed that he could not predict the time frame in which such a catastrophic event could happen. In a paper in the journal Nature, Cummins warned that there was a distinct possibility of a quake measuring 8.5-9 on the Richter scale striking the northern region of Bay of Bengal. Quakes of more than 8 magnitude are known to cause such powerful tsunamis. The densely populated coasts of India, Bangladesh and Myanmar would be the most severely hit by such a tsunami if Cummins's prediction comes true. He studied what geologists call the Arakan subduction zone where the Indian and Southeast Asia plates meet. This stretch underlies all the land and water mass from Java and Sumatra to the eastern Himalayas right up to Arunachal Pradesh. A subduction zone refers to a region where, due to several reasons, two plates collide with one plate sliding over the other, causing earthquakes. Current science theories suggest that the subduction is not strong enough in the northern Bay of Bengal region where it weakens because of an oblique movement instead of a 'pure subduction'. But now, Cummins predicts that there is a distinct possibility of such a 'pure subduction'. He backs it up with historical data of tectonic movement from a 1762 earthquake in the Arakan area of Myanmar. But other scientists the world over have taken the paper with a pinch of salt, though terming the paper as a fair warning. R K Chaddha, project leader for seismology at the National Geophysical Research Institute, said.
