10 March 2025—“Moment tensors are a model to describe earthquake sources based on forces acting at the seismic source,” explains Boris Rösler. “In the 1960s, it was shown that these forces generate a seismic wavefield equivalent to slip on a fault. We can thus describe the geologic process of an … Continue Reading »
A joint statement by SSA President Heather DeShon and President-Elect Susan Bilek 15 February 2025 — The recent termination of thousands of federal employees, including employees within the U.S. Department of the Interior, Department of Energy and Department of Commerce, will undermine the critical scientific expertise required to keep the … Continue Reading »

10 February 2025—Wilnelly Ventura-Valentín’s research as a Ph.D. student at Miami University in Ohio focuses on earthquake swarms, the bursts of seismic activity—small earthquakes all about the same magnitude—that start abruptly and end abruptly. “We don’t know a lot about what triggers this activity,” she explains, “and because we don’t … Continue Reading »
12 January 2026—SSA is pleased to announce the recipients of several of the Society’s awards for 2026. The Harry Fielding Reid Medal, the Charles F. Richter Early Career Award, the Frank Press Public Service Award and the SSA Distinguished Service Award are among the highest honors conferred by the Society. … Continue Reading »
9 January 2025—Earthquakes may be the noisy, attention-getters of seismological research, but geophysicist Daniel Gittins is focused on something a bit quieter. “Creep is the slow, gradual movement along faults that happens without causing an earthquake. Unlike sudden earthquakes, which release a lot of energy, aseismic creep occurs smoothly and … Continue Reading »
