21 July 2026—Sustained supershear earthquake ruptures produce distinct ground motion characteristics compared to subshear earthquakes, according to a study published in the Bulletin of the Seismological Society of America, with potential implications for current building codes and ground motion models. Supershear earthquakes occur when the fault rupture itself moves faster … Continue Reading »
1 July 2026—From a massive but messy collection of reports from people who felt the 1957 magnitude-5.3 Daly City, California earthquake, researchers used the large language model Gemini 2.5 Pro™ to extract data that allowed them to create a shaking intensity map for an earthquake that rocked the San Francisco … Continue Reading »
25 June 2026—As a service to global researchers working on the 24 June 2026 magnitude 7.2 and 7.5 earthquakes in Venezuela, the Seismological Society of America has created a short list of our journal papers related to the region. These papers will be freely available until 16 July 2026. Paige … Continue Reading »
23 June 2026–The Seismic Record (TSR) has earned its first official Clarivate Impact Factor of 5.3, ranking 6th out of 103 journals in the geochemistry and geophysics category. The Impact Factor measures how frequently a journal’s articles are cited by other researchers, serving as a comparable gauge of a publication’s … Continue Reading »
10 June 2026—Researchers combining two methods to reconstruct the rupture evolution of the July 2025 magnitude 8.8. Kamchatka earthquake found the rupture from the megathrust event extended about 500 kilometers from its epicenter. The rupture extent closely overlaps the rupture of the magnitude 9.0 1952 Kamchatka earthquake, according to the … Continue Reading »
10 June 2026—Researchers repurposed an AI model designed for visual identification tasks to detect Bryde’s whale calls contained with seismic data collected in the South China Sea. A whale call can be visualized as a spectrogram, a “snapshot of sound” that shows how the frequencies of the sound signal change … Continue Reading »
