How did this travel a rock of 1300 tons above cliff? Scientists have just discovered this

A giant rock in Tonga installed a wave of ancient tsunami 7000 years ago. The 1300 tons rock traveled at a distance of twice the size of the football field, swept the tremendous force of the wave, according to a new study.

But this was not a normal giant rock. He was also sitting on a 100-foot shelf (30 meters) before surfing to his new site-in infiltration to the huge Sonami that swept the area.

In July 2024, Martin Kuller, a doctoral candidate from the University of Queensland, and his team were doing field work on the Tonga slopes, looking for evidence of the last tsunami. In particular, they were looking for large rocks that could have been implemented, which could tell researchers a lot about the history of tsunami in the areas exposed to the earthquake, such as Tonga.

On one of their last days, some local farmers looking for a rock they might care about. The rock, familiar to the local population Maca LahiOr literally, a “large rock”, which was not studied by scientists. This may have faded searches for previous satellites from the avoidance of tsunami due to the dense vegetation layer.

The rock was made of BRCCIA Coral Limestone, which hints that it came from a place near the coast. Koler said in a statement. The results of the researchers were published in the magazine Marine geology.

The researchers later found a huge gravity in a 100 -foot shelf (30 meters) near the ocean, about 650 feet (200 meters) from the current Boulder site. They also decided that the rock was deposited 6891 years ago, before humans settled on Tonga.

The researchers measured the rocks in 45 x 40 in 20 feet (14 in 12 in 7 meters), the size of a house of approximately two floors. It is now honored to be the third largest tsunami rock in the world. It is the largest rock known to browse a tsunami from a cliff.

Then the team used computer mode Maca Lahi It should be. They concluded that, at least 164 feet (50 meters), and it would take about a minute and a half. Tsunami is likely to reach speeds of more than 70 miles per hour (113 km per hour). It was very huge and strong, and the researchers believe that the landslide, instead of an earthquake, initially raised the wave.

Tonga sees a lot of geological activity that can lead to tsunami, such as The destroyed tsunami in 2022. Co -author, Any Lao, the coastal gymnastics scientist at the University of Queensland, said in a statement that understanding more about past tsunami mechanics could help researchers prepare better for future events.

Lao said: “The analysis strengthens our understanding of the transfer of the wave of rocks to improve coastal services assessments in the areas exposed to Tsunami all over the world.”
