Advancing earthquake science worldwide
15 October 2020–The shape of the Earth may seem stable, but Virginia Tech geophysicist D. Sarah Stamps knows differently. She and her colleagues track its shifting shape millimeter by millimeter, quantifying the horizontal and vertical motions of the tectonic plates to get at the physics behind the plate motions. The … Continue Reading »
14 September 2020–In 2004, Brian Terbush climbed Mt. St. Helens in Washington State. The trip fueled his fascination with volcanoes, and he “jumped on the chance” to go to graduate school to study them further. “I’ve been lucky to get to see lots of volcanoes erupting and get a little … Continue Reading »
17 August 2020–For decades, seismologists have contended with the background “hiss” of the Earth—seismic waves generated by the normal interaction of land, ocean and atmosphere. Their goal has been to find ways to subtract this “noise,” to concentrate on the seismicity generated by earthquakes. But one scientist’s noise is another’s … Continue Reading »
Dear SSA Community: As a Society, we seek to do all we can to make science accessible to all. That goal has inspired a new task force to address diversity and inclusion within our community. Chaired by Aaron Velasco, professor of geological sciences and computational sciences at the University of … Continue Reading »
13 July 2020–Deep long period (DLP) earthquakes occur close to the base of the crust and contain seismic waveforms with frequencies less than 5 Hz—a phenomenon very different from the high frequency, relatively shallow tectonic activity that most people think of as an earthquake. DLP earthquakes are most often associated … Continue Reading »
FROM BILL WALTER, PRESIDENT OF SSA 9 July 2020 — Seismology is a global endeavor, and the international scientific community benefits from a free exchange of people as well as ideas. The Administration’s recent proposal to limit participation by international students in US degree programs would be tragic, both for … Continue Reading »
