A robust tsunami with 49-foot waves that tossed boulders as heavy as tanks inundated Oman about 1,000 years in the past, scientists say.
Scientists from a number of worldwide universities have discovered a number of massive boulders that have been apparently carried inland amid the catastrophic occasion.
“There we recognized 41 massive boulders, which have been apparently carried inland by the drive of the water,” Gösta Hoffmann, from the Institute for Geosciences on the College of Bonn, mentioned in a press release.
The biggest of those rocks weighs about 100 metric tons, which is greater than a Leopard tank. On the rock: Magdalena Rupprechter, GUtech, Oman; to the proper: Gösta Hoffmann, College of Bonn. (Anne Zacke)

WAS SAME-SEX BEHAVIOR IN ANIMALS HARDWIRED FROM THE BEGINNING?
Researchers consider that a number of the boulders have been shaped when the tsunami destroyed components of the cliffs alongside a selected strip of coastal Oman. The biggest boulder weighed in at about 220,000 kilos.
Quartz crystals within the rock allowed scientists to find out how lengthy the boulders have been within the spot the place they have been discovered. “Many of those measurements gave us a worth of about 1,000 years,” mentioned Hoffmann.
The research, which will likely be printed within the journal Marine Geology, additionally means that stress within the Arabian and Eurasian tectonic plates beneath the Arabian Sea can construct up and be unleashed very quick.

“It’s due to this fact extraordinarily vital {that a} tsunami early warning system is put in place for this area,” the geologist mentioned.
