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. 19, 2021 —Ebel looked for the California faults that had magnitude 4 or larger earthquakes occurring at a rate higher than 0.5 earthquakes per year from 1997 to 2016. If the pattern holds, the next magnitude ...
Dec. 8, 2022 —Evidence that a complete stress release may have contributed to the 2011 Tohoku earthquake that broke records. Both sedimentary formations above and below the plate boundary fault lie in the stress ...
Apr. 19, 2021 —A new study finds a naturally occurring 'earthquake gate' that decides which earthquakes are allowed to grow into magnitude 8 or greater. Sometimes, the 'gate' stops earthquakes ...
Apr. 21, 2023 —Faults in the Ridgecrest, California area were very sensitive to solid earth tidal stresses in the year and a half before the July 2019 Ridgecrest earthquake ...
Apr. 9, 2021 —The concentration of the radioactive element radon is known to change in the ground before and after earthquakes. Previous studies have shown elevated radon levels in the atmosphere before the ...
Feb. 16, 2021 —At a glacier near the South Pole, earth scientists have found evidence of a quiet, slow-motion fault slip that triggers strong, fast-slip earthquakes many miles ...
June 26, 2023 —Researchers analyzed the source processes of the twin earthquakes that caused extensive damage in Türkiye and Syria on February 6, 2023. The results revealed that a complex fault network with bends, ...
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 ...
Sep. 23, 2022 —Scientists who drilled deeper into an undersea earthquake fault than ever before have found that the tectonic stress in Japan's Nankai subduction zone is less than expected. The findings are a ...
