Apr. 14, 2023 The 2022 eruption of a submarine volcano in Tonga was more powerful than the largest U.S. nuclear explosion, according to a new study. The 15-megaton volcanic explosion from Hunga Tonga-Hunga ...
Dec. 21, 2021 A new study finds the magnetic field generated by a tsunami can be detected a few minutes earlier than changes in sea level and could improve warnings of these giant ...
May 12, 2022 A new method of detecting mega earthquakes, which picks up on the gravity waves they generate by using deep-learning models, can estimate earthquake magnitude in real time and provide earlier warning ...
Oct. 6, 2022 Some 66 million years ago, a 10-kilometer asteroid hit Earth, triggering the extinction of the dinosaurs. New evidence suggests that the Chicxulub impact also triggered an earthquake so massive that ...
July 19, 2022 Using data from the eruption of the underwater volcano near Tonga in 2022, researchers used disturbances in Earth's upper atmosphere to track the airwaves that cause tsunami. Their findings may ...
Feb. 3, 2022 The Sanriku Coast - which includes present day Iwate and parts of Aomori and Miyagi - has been prone to tsunamis throughout its history. Analyses of tsunami deposits along the coast, however, ...
Apr. 28, 2022 A new method for detecting tsunamis using existing GPS satellites orbiting Earth could serve as an effective warning system for countries worldwide, according to a new ...
Dec. 12, 2022 The powerful volcanic eruption in January 2022 created ripple effects throughout the world's atmosphere and oceans. Analysis of the Hunga Tonga eruption shows how signals from the ionosphere ...
Dec. 9, 2021 A large earthquake off the coast of south-central Chile in 1737 may have caused a substantial tsunami that was absent from historical records. Historical records are used to predict how often ...
Apr. 25, 2023 Researchers develop an early warning system that combines acoustic technology with AI to immediately classify earthquakes and determine potential tsunami risk. They propose using underwater ...
