Advancing earthquake science worldwide
12 July 2022–Using details from historical newspaper accounts and letters, seismologists have learned more about Haiti’s 1860 Jour de Pâques (Easter Sunday) earthquake sequence, and how it might have impacted the country’s most recent devastating earthquakes. The new analysis published in the Bulletin of the Seismological Society of America suggests … Continue Reading »
28 June 2022–An active underground mine can be a seismically noisy environment, full of signals generated by heavy machinery at work and induced seismicity. Now, researchers working with data from a longwall coal mine demonstrate a way to extract and separate the signals generated from mining activity from the background … Continue Reading »
3 May 2022–Including topography—the hills, cliffs and valleys of a landscape—in ground motion models shows where shaking might be most amplified during an earthquake, researchers demonstrate with detailed new models of the Puget Sound region. In their models, Ian Stone of the U.S. Geological Survey and colleagues simulated several magnitude … Continue Reading »
13 April 2022–The rise of fiber-optic distributed acoustic sensing (DAS) in seismology could prove a useful addition to earthquake early warning systems, researchers write in the Bulletin of the Seismological Society of America. DAS uses the tiny internal flaws in a long optical fiber as thousands of seismic sensors. An … Continue Reading »
14 March 2022–Christopher DuRoss of the U.S. Geological Survey, Golden, Adam Ringler of the U.S. Geological Survey, Albuquerque, and Vaclav Vavrycuk of the Institute of Geophysics in the Czech Republic, are the recipients of SSA’s 2021 Outstanding Reviewer awards. In recent interviews, the recipients agreed that reviewing is an essential … 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 »
