Rama Setu: recurrent tsunamis of the past

Here is a remarkable scientific study by Prof. RK Gartia of Manipur University providing evidence for recurring tsunamis in historical and pre-historical periods near the Rama Setu region and along the Tamil nadu coastline from Mahabalipuram. This should provide for caution in undertaking projects like the project disaster called Setu mid-ocean channel and without examing the need for adequate tsunami protection walls along the vulnerable spots (as has been done on Japan coastline). The nation’s coastline should be safeguarded at all costs to save life and property of coastal/marine people of Bharatam.

LUMINESCENCE DATING OF SOME HISTORICAL / PRE-HISTORICAL NATURAL HAZARDS OF INDIA by R.K. GARTIA*

Department of Physics, Manipur University, Canchipur, Imphal – 795 003 (INDIA)

Abstract (The full paper can be downloaded from http://hinduthought.googlepages.com/pasttsunamis.pdf )

The Indian sub-continent is characterized by host of natural hazards like earthquake, tsunami, cyclones, floods, landslides / mudflows. It is necessary to build-up a database of historical / pre-historical natural hazards for planning scenarios for emergency response to various them. In short, there is a vast scope of providing chronology to hazardous events by using known techniques of dating including luminescence dating which has an excellent window span down from few hundred years to one hundred thousand years. In this work we report the dates of some historical / pre-historical natural hazards of India. In particular we focus on three kinds of natural hazards namely, earthquakes, tsunami, and mudflows. For example of earthquake we cover a historical earthquake of Manipur that created two massive fissures at Kumbi, 25 Km from the state capital, Imphal. For pre-historical ones, we cover Assam-Shillong area known for its highest levels of seismicity in India. We demonstrate the evidence of a paleo-tsunami that devastated Mahabalipuram near Chennai. Incidentally, Mahabalipuram was badly affected by the great tsunami of 26th Dec 2004. Finally, luminescence dating technique has been applied to some historical / pre-historical mudflows of Manipur. A recent mudflow on 10th July 2004 damaged more than 90 houses, block National Highway-39, the life-line of Manipur for more than a fort-night.
