Advancing earthquake science worldwide
14 March 2022–As the Regional ShakeAlert Coordinator for the Pacific Northwest Seismic Network, Mouse Marie Reusch often fields questions about earthquake early warning from the public. “For earthquake early warning, a big misconception is that it’s prediction, and it’s not,” Reusch explained. “An earthquake has already started somewhere, and we’re … Continue Reading »
9 March 2022–Papers on distributed acoustic sensing (DAS) and machine learning techniques were among the topics covered by the top 20 most-downloaded papers published by the SSA family of journals in 2021. The ranking of all papers noted below reflect download numbers through 31 December 2021: Y.J. Tan et al., … Continue Reading »
2 March 2022–Researchers were able to observe stress changes before and during an earthquake induced by hydraulic fracturing in Alberta, Canada, with the help of a phenomenon called seismic anisotropy. Seismic anisotropy refers to changes in the velocity of seismic waves dependent on the “fabric” of the rocks that the … Continue Reading »
17 February 2022–Six leading experts in seismic tomography will present their most recent research and their perspective on where their field is headed at Seismic Tomography: What Comes Next? The in-person conference, presented by the Seismological Society of America, is scheduled for 28-30 October 2022 in Toronto, Canada. The keynote … Continue Reading »
14 February 2022–At the Colorado School of Mines, where Delaine Reiter was an undergraduate, she found her interests in math and Earth physics turned toward exploration seismology and near-surface studies. “I was looking at big reflection surveys of the very shallow crust, trying to find oil and gas plays,” she … Continue Reading »
9 February 2022–Field surveys conducted in the days after the 7 January 2020 Puerto Rico earthquake documented more than 300 landslides and severe liquefaction in southern coastal regions, according to a new study by U.S. Geological Survey and University of Puerto Rico Mayagüez researchers. The ground failure that resulted from … Continue Reading »
