21 July 2023–Researchers at a field site in Victoria, Australia are among the first to use fiber optic distributed acoustic sensing (DAS) for high-precision tracking of induced seismicity from a small carbon dioxide (CO2) injection, according to a new study published in Seismological Research Letters. The CO2CRC Otway Project in … Continue Reading »
17 July 2023–The Seismological Society of America (SSA)’s journal The Seismic Record is now included in the Directory of Open Access Journals (DOAJ), a key community-driven service advocating best practices and standards in open access. The journal was included in DOAJ after meeting a rigorous set of qualifications with respect … Continue Reading »
28 June 2023–Seismologists agree that foreshocks are the most widely identified signal of an upcoming mainshock earthquake. But do these foreshock sequences have distinctive characteristics that separate them from aftershock sequences, and could these characteristics be used to help forecast mainshocks? In a new paper in Seismological Research Letters, Nadav … Continue Reading »
23 May 2023–Three studies now published in the open-access journal The Seismic Record offer an initial look at the February 6, 2023 earthquakes in south-central Türkiye and northwestern Syria, including how, where, and how fast the earthquakes ruptured and how they combined as a “devastating doublet” to produce damaging ground … Continue Reading »
5 April 2023–Seismic arrays deployed in California’s Long Beach and Seal Beach areas detected more than a thousand tiny earthquakes over eight months, many of them located at surprisingly shallow depths of less than two kilometers below the surface. The findings, reported in Seismological Research Letters, confirm that the region’s … Continue Reading »
8 March 2023–When it comes to making a rapid estimate of ground motion and moment magnitude for an earthquake, using data from Global Navigation Satellite Systems (GNSS) might be a good alternative or addition to data from seismic stations. Researchers were able to compare how well each type of data … Continue Reading »
