A 1200 tons of Boulder in Tonga overflows the ground when a 50-meter-high wave fires a 30-meter-long cliff.
“It’s not just a stone; this is the biggest wave of the wave found on a cliff and the third largest rock in the world, so it really needs these giant forces to move it in a very high place,” as Martin Köhler At the University of Queensland in Brisbane, Australia.
While the more are known to some locales as different, that means great stone, the scientists have not been studied.
Köhller and his companions conducted the Tonga fieldwork in July 2024 looking for stones deposited in the tsunami on the cliffs. On their last day of the Pacific country, the villagers told them a stone they want to see.
“We never look forward to finding such a big boulder last minute in our farming and I know it’s easy to discover,” Köhler said.
At 14 meters long, 12 meters wide and nearly 7 meters height, it was a “odd” rice in rice. It annoys past searches for possible tsunami stones in satellite images because they have plants growing over its top and forests around it.
After seeing the boulder, researchers found a large cliffftop gash above the ocean, 200 meters away, as they thought the stone was torn.
Next, the team uses the computer models to determine how a large stone, is high at sea level, can be moved away from the ground.
The transfer it should be a wave with a minimum height of 50 meters and 90-second periods, which means to pass over 22 meters per second, says Köhler. Thought that such great tsunami is probably quite local and caused by a nearby groundwater.
Dating reveals the age of 6891 years, thousands of years before the person’s settlement on the island.
“It is, for me, it’s hard to believe it is a 50-meter wave because we haven’t seen or learned a big wave before,” Köhler said. “But if you think this much boulder is sitting at 200 meters of land on a cliff on 39-meter-meter-high cliff, then easier to understand.”
Only two tsunami-decoscited boulders found in the land larger: The Obiishi rock in Shimoji-Shima, Japan, with a 1500 tons weight.
