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 »
3 January 2023–Seafloor video collected by a remotely operated vehicle off the coast of Puerto Rico indicates that an underwater landslide was not the cause of a devastating tsunami that hit the island’s west coast after a 1918 earthquake. The proposed scar of the landslide is too old to be … Continue Reading »
25 November 2022–A study of hydroacoustic, acoustic and seismic waves from underwater explosions off the French coast could help guide the disposal of unexploded World War II ordnance (UXO) in those waters, according to a new study published in the Bulletin of the Seismological Society of America. The French Navy … Continue Reading »
