“It is possible such an eruption could trigger nearby activity,” Kronenberg said. The result can be tsunamis because they can be triggered by any disturbance of the seafloor that quickly moves large volumes of seawater, such as faults that suddenly change the shape of the seafloor.”Ĭould the Tonga explosion mean future eruptions in the area are possible?
“And it appears that water entering into the volcano internally added to its explosiveness. “Krakatoa was truly epic, and Tonga was obviously devastating,” Kronenberg said.
Some have compared the Tonga eruption as similar to Krakatoa, and NASA has said the Tonga explosion was at least 500 times more powerful than the bomb dropped on Hiroshima in 1945. The largest eruption ever is believed to be the eruption of Krakatoa, which exploded near Indonesia in 1883 and killed more than 36,000 people. Helens, which exploded in 1980, is considered the most powerful volcanic eruption in U.S. Helens, which exploded a few decades ago.” Vesuvius that covered Pompei in Italy and Mt. “This is why we are concerned about the volcanoes in the Oregon, Washington and Alaska regions,” Kronenberg said. “However, the Tonga subduction zone is a large one and the entire Southwest Pacific has what we call ‘stratovolcanoes.’ These are extremely powerful volcanoes and are also the kinds that include Mt. Strong M6.2 earthquake hits Tonga at intermediate depth Saturday, JStrong and shallow M6.2 earthquake hits Tonga region Thursday, JanuShallow M6.3 earthquake hits south of Tonga Saturday, MaShallow M6. “In general, the volcanoes around the Pacific Rim are much more powerful and explosive than Hawaiian-type volcanoes, mostly because of the volatile content and magma compositions in them,” Kronenberg said. The eruption caused a huge ash cloud to form on many of the islands, killed at least three people, and could be heard in New Zealand and seen from space. The Polynesian country has about 170 islands, and is 500 miles east of Fiji. Halbouty Chair in Geology at Texas A&M, said the eruption on Tonga likely ranks among the strongest in at least 30 years. No tsunami threat from the earthquake has been reported. The quake struck at a depth of 14.5 kilometres about 219 kilometres north west of the island of Pangai, at 7:40pm local time. The recent violent volcanic eruption on the Pacific island nation of Tonga is believed to be one of the strongest ever recorded, and future eruptions could be possible, according to a Texas A&M University geophysicist.Īndreas Kronenberg, professor and holder of the Michael T. /news/tonga-earthquake-volcanic-eruption/100786950 A magnitude 6.2 earthquake has struck near the Pacific nation of Tonga, the US Geological Survey reports.
