3 January 2024–Seismic events that coincided with sudden drops in pressure within the Nord Stream 1 and 2 natural gas pipelines in September 2022 alerted the world to the rupture of pipelines in the western Baltic Sea. The suspected act of sabotage, which reportedly used explosive charges to rupture the … Continue Reading »
14 December 2023–In their rapid characterization of the magnitude 6.8 Al Haouz earthquake in Morocco, researchers from the U.S. Geological Survey’s National Earthquake Information Center (NEIC) suggest that the earthquake ruptured roughly 25 kilometers deep beneath the surface. The USGS source modeling, published in The Seismic Record, shows a compact … Continue Reading »
13 December 2023–Using questionnaires created to determine whether a particular earthquake is natural or induced by human activity, a panel of experts concluded that the November 2022 magnitude 5.2 Peace River earthquake sequence in Alberta, Canada was likely to be induced. The case study published in Seismological Research Letters was … Continue Reading »
20 November 2023–Last year with your help, the SSA Annual Meeting Travel Fund supported 23 students and early-career members attending our 2023 meeting in Puerto Rico. SSA needs your generosity again to fully fund its 2024 Annual Meeting Travel Grant Program to bring even more of your future colleagues to … Continue Reading »
14 November 2023–The devastating September 2023 earthquake in Morocco and the unusual series of October 2023 earthquakes in Afghanistan are painful reminders of the seismic hazard that exists even in slowly deforming mountain belts away from major plate boundaries. Earthquakes take place infrequently in these regions, but their impacts can … Continue Reading »
7 November 2023–New maps of more than 1,000 deep-seated landslides in the Puget Lowlands of Washington State provide evidence of the last major earthquake along the Seattle Fault about 1,100 years ago—and may also hold traces of older earthquakes along the fault. Clusters of landslides offer a potential record of … Continue Reading »
