Advancing earthquake science worldwide
15 April 2026—When the edge of a Greenland glacier breaks off into the sea to become an iceberg, can a global seismic network “hear” it? The answer is yes—but only if the event is a large one. And it helps to pair the resulting surface seismic waves with satellite observations … Continue Reading »
15 April 2026— A new look at the Juan de Fuca tectonic plate beneath the coast of northern Oregon suggests this subducting slab is shallower than previously thought, with impacts on potential peak ground shaking during a Cascadia megathrust earthquake. The Juan de Fuca plate dives beneath the North American … Continue Reading »
REVISION issued May 6, 2026: The original release stated in its seventh paragraph that, “An uncontrolled explosion of a subcritical experiment could potentially release radioactive material at levels harmful to workers within PULSE as well as nearby Nevada communities.” The Defense Nuclear Facilities Safety Board has asked this sentence to … Continue Reading »
13 April 2026—Zhigang Peng studies the physics of faulting, earthquake triggering, fault zone structures, earthquakes swarms, slow earthquakes, but lately he’s added a few other topics that veer away from the usual. Vibrations in a sewer pipe. Exploding rock outcrops. “In particular, what I have been working on the past … Continue Reading »
3 April 2026—Following the February application cycle, SSA awarded 11 grants to members at all career stages across our global community. The grants, funded by generous donations to the Society, will enable these scientists to share research, make professional connections and create events that help advance seismology. Community Grants SSA … Continue Reading »
1 April 2026—Slow roiling convection currents deep within the Earth’s mantle, which are associated with the movements of tectonic plates, also deform the material of the mantle itself. Now, a new study in The Seismic Record confirms that much of this deformation in the lowest level of the mantle occurs … Continue Reading »
