Advancing earthquake science worldwide
20 November 2019–The terms may seem interchangeable to a layperson, but “hazard” and “risk” mean very different things in earthquake science. A seismic hazard is a natural phenomenon such as the level of ground shaking caused by an earthquake. Seismic risk, on the other hand, refers to the probability that … Continue Reading »
19 November 2019–Hand-dug trenches around Leigh Lake in Grand Teton National Park in Wyoming reveal evidence for a previously unknown surface-faulting earthquake in along the Teton Fault—one occurring about 10,000 years ago. Together with evidence from the site of a second earthquake that ruptured around 5,900 years ago, the findings … Continue Reading »
6 November 2019–The season that an earthquake occurs could affect the extent of ground failure and destruction that the event brings, according to a new look at two historical earthquakes that occurred about 100 years ago near Almaty, Kazakhstan. In a paper published in Seismological Research Letters, researchers conclude that … Continue Reading »
31 October 2019–The Earthquake Engineering Research Institute (EERI) and the Seismological Society of America (SSA) are pleased to announce that Julian J. Bommer, a Senior Research Investigator at Imperial College London, is the 2020 recipient of the William B. Joyner Lecture Award. Bommer will deliver the Joyner Lecture at the … Continue Reading »
Isabel Hong has always been enthralled with earthquakes. As an elementary student growing up in Washington state, she made frequent leaps under her school desk for earthquake drills. And when an earthquake finally rocked her hometown, she felt prepared. “I wasn’t fearful. I knew just what to do,” recalled Hong, … Continue Reading »
29 October 2019–By combining models of magnitude 9 to 9.2 earthquakes on the Cascadia Subduction Zone with geological evidence of past coastal changes, researchers have a better idea of what kind of megathrust seismic activity was behind the 1700 Cascadia earthquake. The analysis by Erin Wirth and Arthur Frankel of … Continue Reading »
