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 »
2 March 2023–Within minutes, a statistical model based on a global database of public reports of ground shaking can be used to identify an earthquake as a high- or low-impact event, according to a new study published in The Seismic Record. High-impact earthquakes, as defined by the study, are those … Continue Reading »
28 February 2023–At one of the world’s largest emission fields of non-volcanic carbon dioxide in southern Italy, researchers have detected a complex variety of seismic tremor signals, captured by a seismic array deployed in the region in the summer of 2021. In their study published in the Bulletin of the … Continue Reading »
