1 November 2023–The chance discovery of a note written in a 15th century Hebrew prayer book fills an important gap in the historical Italian earthquake record, offering a brief glimpse of a previously unknown earthquake affecting the Marche region in the central Apennines. Paolo Galli, who found the note in … Continue Reading »
One of the biggest challenges for earthquake early warning systems (EEW) is the lack of seismic stations located offshore of heavily populated coastlines, where some of the world’s most seismically active regions are located. In a new study published in The Seismic Record, researchers show how unused telecommunications fiber optic … Continue Reading »
10 October 2023–Fiber optic cable snaking beneath the Penn State campus, passing under the athletic buildings and campus fields, can detect seismic waves generated by lightning storms. But what exactly causes lightning quakes—and why do we care about them? A new study published in the Bulletin of the Seismological Society … Continue Reading »
12 September 2023–Fires that raged in the days following the 1 September 1923 magnitude 7.9 Kantō earthquake killed roughly 90% of the 105,000 people who perished in and around Tokyo, making it one of the deadliest natural disasters in history—comparable to the number of people killed in the World War … Continue Reading »
28 August 2023–After an earthquake strikes in an area with a buried gas pipeline network, it can be critical to identify where potential damage to the pipeline might have occurred—especially since these networks can cover hundreds of kilometers and may sometimes not be easily accessible. Forecasts of pipeline damage typically … Continue Reading »
09 August 2023–A telecommunications fiber optic cable deployed offshore of Oliktok Point, Alaska recorded ambient seismic noise that can be used to finely track the formation and retreat of sea ice in the area, researchers report in The Seismic Record. Andres Felipe Peña Castro of the University of New Mexico … Continue Reading »
