Advancing earthquake science worldwide
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 »
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 »
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 »
11 November 2022–Caltech Hall, a 55-year-old nine-story reinforced concrete building on the Caltech campus, has been getting structurally stiffer over the past 20 years, according to a new report published in The Seismic Record. Previous work by seismologists and engineers had documented the building softening—that is, decreasing in stiffness—from its … Continue Reading »
26 August 2022–Using machine learning to sift through a decade’s worth of seismic data, researchers have identified hundreds of thousands of microearthquakes along some previously unknown fault structures in Oklahoma and Kansas. The newly identified microearthquakes allowed the seismologists to map and measure earthquake clusters in the region, which has … Continue Reading »
6 July 2022–Researchers used a fiber optic cable on the ice cap of an Icelandic subglacial volcano to detect low-frequency volcanic tremor, suggesting this technology could be useful in monitoring other ice-covered volcano systems. Their research published in The Seismic Record indicates that the floating ice cap, part of the … Continue Reading »
