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. 20, 2023 Even though most of the economic losses are concentrated in California and along the West Coast due to that region's high seismic hazard levels, significant population, and building exposure, ...
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 ...
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 ...
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 ...
Oct. 31, 2022 About 14% of magnitude 6.7 or greater strike-slip earthquakes since 2000 have been supershear. That's 50% more than previously thought. Supershear earthquakes occur when a fault ruptures faster ...
Feb. 25, 2022 Using the Santa Cruz Mountains as a natural laboratory, researchers have built a 3D tectonic model that clarifies the link between earthquakes and mountain building along the San Andreas fault for ...
Feb. 28, 2022 The central section of the great fault spanning California, thought to be creeping along harmlessly at the moment, has experienced big quakes in the past, says a new ...
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 ...
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 ...
