‘Earth’s oldest quake took place in India’
NEW DELHI: An international team of scientists has found geological markers in eastern India that show an earthquake took place there more than 1,600 million years ago, the Press Trust of India reported on Monday.
“They are among the earliest records of earthquakes known in the Earth’s history,” the team says in a paper to appear in the next issue of the Dutch-published journal ‘Sedimentary Geology’.
The scientists from India, Japan and Poland analyzed sedimentary rocks in eastern India and found unusual formations up to a kilometer deep in sediments deposited between 1,600 and 2,100 million years ago. “The layers show deformations that have never been described before,” lead author Rajat Mazumder, a post-doctoral fellow in the University of Munich’s geology department, told the news agency.
Mazumder co-wrote the report with AJ van Loon of Poland’s University of Silesia and Makoto Arima, of Yokohama University. AFP
