Dark Fiber Helps Pick Up Acoustic Signals of Iceland Meteoroid


17 November 2022–Data collected by a large-N seismic array and distributed acoustic sensing (DAS) in Iceland offer one of the most detailed acoustic fingerprints of a meteoroid entering and disintegrating in the atmosphere. The dense record, described in Seismological Research Letters, allowed the researchers to distinguish acoustic phases that are … Continue Reading »

Caltech Hall Is Getting Stiffer, According to Decades of Data

Caltech Hall

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.
