13 June 2018–Since 2007, the Collaboratory for the Study of Earthquake Predictability or CSEP has been studying earthquake forecast models to find out how well each model stacks up against its competitors, and how well each forecast predicts later seismic activity. At four centers in California, New Zealand, Europe and … Continue Reading »
17 May 2018–SSA plans to hold its annual meeting in San Juan, Puerto Rico in 2022, the society’s new president Peter Shearer announced 14 May at the opening ceremony that welcomed participants to the Seismology of the Americas conference. The 14-17 May gathering in Miami brought together SSA and the … Continue Reading »
17 May 2018–Repeating seismic events—events that have the same frequency content and waveform shapes—may offer a glimpse at the movement of magma and volcanic gases underneath Turrialba and Poas, two well-known active volcanoes in Costa Rica. At the 2018 SSA Annual Meeting, Rebecca Salvage of the Observatorio Vulcanologico y Sismologico … Continue Reading »
17 May 2018–The shape of the continental shelf off the southern Mexican coast played a role in the formation of long-lasting tsunami edge waves that appeared after last September’s magnitude 8.2 earthquake, according to researchers speaking at the SSA 2018 Annual Meeting. Edge waves are coastal waves generated by a … Continue Reading »
17 May 2018–Can altering the amount or rate of fluid injection and production in an oil and gas field or carbon storage site affect induced earthquakes in that field? A physics-based simulation presented at the 2018 SSA Annual Meeting suggests that this type of “active pressure management” can be useful … Continue Reading »
16 May 2018–This spring, researchers will release an expanded database that covers the geometry of most of the world’s subducting slabs, the massive pieces of the Earth’s crust that sink into the mantle at tectonic plate boundaries. Called Slab2, the updated database will help researchers determine the impact of 3-D … Continue Reading »
