Advancing earthquake science worldwide
22 October 2019–Major landslides triggered by the 1964 magnitude 9.2 Great Alaska earthquake responded to, but were not reactivated by, the magnitude 7.1 Anchorage earthquake that took place 30 November 2018, researchers concluded in a new study published in Seismological Research Letters. The shaking that accompanied the 2018 earthquake was … Continue Reading »
2 October 2019–The International Monitoring System is the top global seismic network for monitoring nuclear weapon tests around the world. To expand the system’s detection capabilities, however, international monitors should seek out the data, methods and expertise of smaller regional seismic networks. In a paper published as part of an … Continue Reading »
16 September 2019–Earthquake faults have short memories—or at least, that’s what the traditional earthquake cycle model suggests. Based on the elastic rebound theory proposed by Harry Fielding Reid after the 1906 San Francisco earthquake, the traditional model assumes that each earthquake in an area occurs independently of one another, and … Continue Reading »
5 September 2019–The eastern Pacific Ocean margin stretching from Mexico to southern Chile offers seismologists a “natural laboratory” in which to study and test ideas about the processes of subduction zones, which are associated with some of the world’s largest recorded earthquakes in the region, as well as phenomena such … Continue Reading »
SSA announces the 2020 election to select four new members to serve three-year terms on the Board of Directors. The seven candidates and their statements are presented below, in alphabetical order by last name; in order by last name, these candidates are Annemarie Baltay, Susan Bilek, Matthew Gerstenberger, Hiroshi Kawase, … Continue Reading »
15 August 2019–Seismic networks depend on good instrumentation. But testing sensitive seismic instruments to make sure they’re working right can be a challenge, as Adam Ringler, a physical scientist with the U.S. Geological Survey, knows well. “Seismometers aren’t only sensitive to ground motion, which you want, they’re also sensitive to … Continue Reading »
