SAN JOSE, Calif. — Worried that an earthquake could collapse a big dam south of San Francisco, officials have ordered its reservoir to be completely drained by October to reduce the risk of floodwaters spilling into Silicon Valley. The 240-foot …
Federal agencies have completed the first high-resolution mapping of a fast-moving underwater tectonic fault that extends from Vancouver Island, Canada, to southeast Alaska. Researchers from the National Oceanic and Atmospheric Administration and the U.S. Geological Survey finished the comprehensive mapping …
With a focus on tectonic plate movement, induced quakes and subperils, earthquake models continue to evolve, according to Andrew O’Donnell, senior engineer at AIR Worldwide. Though earthquake modeling has been around awhile, O’Donnell said changes in the models have improved …
Taiwan launched a database Monday to inform residents about which areas might be susceptible to creating potentially catastrophic sinkholes in the event of one of the island’s frequent earthquakes. The Central Geological Survey’s research tool shows the potential for soil …
On the count of three, a scrum of Washington sixth graders flung themselves in the air, landing with a thud that vibrated the ground under their feet. Nearby, their classmates huddled around a computer, watching jagged tracings scroll across the …
An engineering expert says the dam that supplies drinking water to roughly 60 percent of the state’s population could likely withstand an earthquake. University of Rhode Island Assistant Professor Aaron Bradshaw says he worried the soil underneath Rhode Island’s largest …
A new federal earthquake map dials up the shaking hazard just a bit for about half of the United States and lowers it for nearly a quarter of the nation. The U.S. Geologic Survey updated Thursday its national seismic hazard …
There may be previously unknown earthquake faults running through Spokane and the surrounding area, the U.S. Geological Survey said Friday. The federal agency conducted an airborne study of the Spokane area last spring and found evidence of earthquake faults. Scientists …
Geologists say new research shows the two main fault lines in the Salt Lake City area will erupt at the same time. That would make the 7-magnitude quake that is expected to hit any year even bigger. The Salt Lake …
Central Idaho’s Blaine County is a big draw for tourists to its towns like Sun Valley and Ketchum, but what visitors may not realize is the region’s potential to be shaken by strong earthquakes. To that end, University of Idaho …
