3 January 2023–Seafloor video collected by a remotely operated vehicle off the coast of Puerto Rico indicates that an underwater landslide was not the cause of a devastating tsunami that hit the island’s west coast after a 1918 earthquake. The proposed scar of the landslide is too old to be … Continue Reading »
30 November 2022–So far, the career of Joses Omojola has moved from water to oil to salt. His first interest, in hydrogeology, came about in high school after he watched his first water borehole being drilled. “A geologist came over to me, explaining about the different sediments they were bringing … Continue Reading »
25 November 2022–A study of hydroacoustic, acoustic and seismic waves from underwater explosions off the French coast could help guide the disposal of unexploded World War II ordnance (UXO) in those waters, according to a new study published in the Bulletin of the Seismological Society of America. The French Navy … Continue Reading »
17 November 2022–Data collected by a large-N seismic array and distributed acoustic sensing (DAS) in Iceland offer one of the most detailed acoustic fingerprints of a meteoroid entering and disintegrating in the atmosphere. The dense record, described in Seismological Research Letters, allowed the researchers to distinguish acoustic phases that are … Continue Reading »
11 November 2022–Caltech Hall, a 55-year-old nine-story reinforced concrete building on the Caltech campus, has been getting structurally stiffer over the past 20 years, according to a new report published in The Seismic Record. Previous work by seismologists and engineers had documented the building softening—that is, decreasing in stiffness—from its … Continue Reading »
28 October 2022–Fan-Chi Lin likes to travel. Some of his favorite destinations are the U.S. national parks, “and I’ve always been curious about how seismology can help us to learn more about the geological features we observe there,” he said. Now, one of his largest research projects involves one of … Continue Reading »
