May 31, 2022 Lake Cahuilla went through many cycles of filling and drying out over thousands of years. A new study used radiocarbon dating to determine the timing of the last seven periods of filling during the ...
May 9, 2022 In June 2019, a magnitude 4.0 earthquake occurred beneath Lake Erie just off the shoreline of Ohio, about 20 miles northeast of ...
Apr. 18, 2022 In disaster mitigation planning for future large earthquakes, seismic ground motion predictions are a crucial part of early warning systems. The way the ground moves depends on how the soil layers ...
Apr. 13, 2022 In a remote area, a mix of geophysical methods identifies magma transfer below the seafloor as the ...
Mar. 29, 2022 Researchers presented the results of efforts to perform global full waveform inversions of the Earth using the Frontera supercomputer. They used data from 300 earthquakes to construct the new global ...
Mar. 24, 2022 Researchers have identified irregular rupture propagation during the 2010 El Mayor-Cucapah earthquake in Mexico by incorporating teleseismic P waveform inversion with traditional modeling, allowing ...
Mar. 22, 2022 Kinematic plate reconstructions and high-resolution global dynamic models developed to quantify the amount of Pacific Plate motion change associated with the Hawaiian -- Emperor Bend. Scientists are ...
Mar. 16, 2022 Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new ...
Mar. 14, 2022 By analyzing the chemistry of over 200 geothermal springs, researchers have identified where the Indian Plate ends beneath Tibet, debunking some long-debated theories about the process of continental ...
Mar. 10, 2022 The Global Navigation Satellite System associated with a Japanese cell phone carrier can enhance monitoring of crustal deformation changes for earthquake early warning ...
Mar. 9, 2022 Earth's thin crust softens considerably when it dives down into the Earth attached to a tectonic plate. That is demonstrated by X-ray studies carried out on a mineral which occurs in large ...
Mar. 8, 2022 By examining earthquake models from a fresh perspective, engineers now show that the earthquake fracture energy -- once thought to relate to how faults in the Earth's crust weaken -- is related ...
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 ...
Mar. 1, 2022 Researchers have developed a new technique by studying the age of ancient grains of sand from beaches, rivers and rocks from around the world to reveal previously hidden details of the Earth's ...
Feb. 28, 2022 Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie ...
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 ...
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. 24, 2022 An earth scientist has discovered evidence of an ancient underwater landslide and associated tsunami in the Gulf of Aqaba, a subsidiary of the Red Sea, that should serve as a warning for many nations ...
Feb. 24, 2022 In July 2019, a series of earthquakes including two major shocks of magnitude 6.4 and 7.1 a day apart struck near Ridgecrest, CA, between Los Angeles and Las Vegas. For local residents, it was a ...
Feb. 14, 2022 Within the next 30 years, a highly destructive Nankai Trough megathrust earthquake is predicted to hit southwest Japan. Understanding long-term slow slip events that occur along the plate interface ...
