3 December 2019–Each hair-thin glass fiber in a buried fiber optic cable contains tiny internal flaws—and that’s a good thing for scientists looking for new ways to collect seismic data in places from a busy urban downtown to a remote glacier. In Seismological Research Letters, California Institute of Technology seismologist … Continue Reading »
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 »
