Dec. 14, 2021 —The San Andreas and San Jacinto faults have ruptured simultaneously at least three times in the past 2,000 years, most recently in 1812, according to a new study by ...
Feb. 3, 2022 —Researchers unveiled a physical model that yields an unprecedented, high-resolution look at the slip rates of faults, which determine the likelihood of ...
Oct. 20, 2020 —A paleoseismic trench dug across the Gales Creek fault, located about 35 kilometers (roughly 22 miles) west of Portland, Oregon, documents evidence for three surface-rupturing earthquakes that took ...
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 ...
Apr. 7, 2021 —The properties of the magma inside a volcano affect how an eruption will play out. In particular, the viscosity of this molten rock is a major factor in influencing how hazardous an eruption could be ...
Feb. 16, 2023 —New research on friction between faults could aid in predicting the world's most powerful earthquakes. Researchers discovered that fault surfaces bond together, or heal, after an earthquake. A ...
Oct. 7, 2020 —An unusually shallow earthquake triggered by hydraulic fracturing in a Chinese shale gas field could change how experts view the risks of fracking for faults that lie very near the Earth's ...
Mar. 2, 2022 —Researchers were able to observe stress changes before and during an earthquake induced by hydraulic fracturing in Alberta, Canada, with the help of a phenomenon called seismic ...
Jan. 18, 2023 —New findings begin to fill major gaps in understanding about how geological faults behave and appear as they deepen, and they could eventually help lead future researchers to develop better ...
Nov. 16, 2021 —根据物理学,从earthquak地震波es should travel in a four-leaf clover pattern, but in the real world they behave more like ripples in a pond. New research has found the pattern ...
