28 June 2023–Seismologists agree that foreshocks are the most widely identified signal of an upcoming mainshock earthquake. But do these foreshock sequences have distinctive characteristics that separate them from aftershock sequences, and could these characteristics be used to help forecast mainshocks? In a new paper in Seismological Research Letters, Nadav … Continue Reading »
19 June 2023–Interested in math and science early on, and looking for a job that would benefit society, Greg McLaskey went to college to study civil engineering. “The thing that excited me the most about civil engineering was non-destructive testing,” he recalled, so he was soon learning all about wave … Continue Reading »
23 May 2023–Three studies now published in the open-access journal The Seismic Record offer an initial look at the February 6, 2023 earthquakes in south-central Türkiye and northwestern Syria, including how, where, and how fast the earthquakes ruptured and how they combined as a “devastating doublet” to produce damaging ground … Continue Reading »
22 May 2023–Simona Gabrielli studies seismic attenuation, or what happens when a seismic wave interacts with its surrounding medium. She compares it to how a stone dropped into a pond sends ripples through the water, and the ripples change direction depending on what they meet as they move across the … Continue Reading »
Leer en Español 20 April 2023–Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench that occurred between 1470 and 1530, according to research reported at the Seismological Society of America (SSA)’s 2023 Annual Meeting. These … Continue Reading »
20 April 2023–Staff in public and private hospitals in Mexico City are likely to follow well-established and reinforced earthquake early warning (EEW) protocols for evacuation, according to an ongoing study. Overall, staff are likely to follow the protocols especially when they are “reinforced with drills that help practice the correct … Continue Reading »
