In a new paper published in the journal Nature, an international team of scientists said that the exceptional
As these waves convergedOn the other hand, energy was continuously pumped into the tsunami, which caused it to increase in size, spread much further, faster and longer.
Eruption of Hunga Tonga-Hunga Ha'apai volcanoJanuary 15, 2022 was the largest volcanic eruption of the 21st century and the largest eruption since Krakatoa in 1883. The explosion was hundreds of times more powerful than the atomic bomb that was dropped on Hiroshima.
The eruption became a source of both atmosphericdisturbances and extremely fast-moving tsunami waves that have been recorded all over the world. This puzzled scientists. “The idea that tsunamis can be caused by atmospheric waves that result from volcanic eruptions is not new. But this was first recorded by modern instruments with a high density of measurements throughout the world. This allowed us to finally unravel the exact mechanism behind these unusual phenomena,” said Ricardo Ramalho, co-author of the study and a member of the School of Earth and Environmental Sciences at Cardiff University.
AGVs are very long sound waves,propagating under the influence of gravity. They can cut through both the ocean depths and the atmosphere at the speed of sound. They arise as a result of volcanic eruptions or earthquakes. Given Tonga's shallow water location, the interaction of energetic AGWs with the water surface was inevitable, the scientists note.
