Advancing earthquake science worldwide
Leer en Español 18 April 2023–In the wake of the 2020-2021 Southwest Puerto Rico earthquake sequence, researchers asked emergency responders and residents in affected communities about the information they needed to prepare for the next earthquake. Residents surveyed door to door and in focus groups said they wanted to know … Continue Reading »
18 April 2023–Ocean-based hydrophones in the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO)’s seismoacoustic monitoring network could provide a better look at how ocean temperatures are changing over time, according to a presentation at the Seismological Society of America (SSA)’s 2023 Annual Meeting. Finding new ways to monitor ocean temperatures is important … Continue Reading »
14 April 2023–As he studied subduction zone seismicity, Wasja Bloch noticed that water was sometimes used as a wild card when it came to explaining what lays below these complex tectonic plate margins. “If people do interpretations of subsurface images and something’s odd, they sometimes pull the ‘fluid joker,’” Bloch … Continue Reading »
5 April 2023–Seismic arrays deployed in California’s Long Beach and Seal Beach areas detected more than a thousand tiny earthquakes over eight months, many of them located at surprisingly shallow depths of less than two kilometers below the surface. The findings, reported in Seismological Research Letters, confirm that the region’s … Continue Reading »
8 March 2023–When it comes to making a rapid estimate of ground motion and moment magnitude for an earthquake, using data from Global Navigation Satellite Systems (GNSS) might be a good alternative or addition to data from seismic stations. Researchers were able to compare how well each type of data … Continue Reading »
6 March 2023–As a non-traditional student, Kevin Ward went back to school “not even clear that I was going back for anything in the geosciences,” he said. “I kind of stumbled upon it when I was taking general ed classes.” “I was always good at math and physics, but then … Continue Reading »
