2 March 2022–Researchers were able to observe stress changes before and during an earthquake induced by hydraulic fracturing in Alberta, Canada, with the help of a phenomenon called seismic anisotropy. Seismic anisotropy refers to changes in the velocity of seismic waves dependent on the “fabric” of the rocks that the … Continue Reading »
9 February 2022–Field surveys conducted in the days after the 7 January 2020 Puerto Rico earthquake documented more than 300 landslides and severe liquefaction in southern coastal regions, according to a new study by U.S. Geological Survey and University of Puerto Rico Mayagüez researchers. The ground failure that resulted from … Continue Reading »
15 December 2021–Just days after a 2020 magnitude 5.1 earthquake in Tangshan, China, researchers turned nearly 8 kilometers of unused telecom fiber optic cable into a seismic array that detected dozens of aftershocks that were missed by permanent seismic stations. The rapid deployment of the distributed acoustic sensing (DAS) technology … Continue Reading »
25 August 2021–The Codex Telleriano Remensis, created in the 16th century in Mexico, depicts earthquakes in pictograms that are the first written evidence of earthquakes in the Americas in pre-Hispanic times, according to a pair of researchers who have systematically studied the country’s historical earthquakes. Gerardo Suárez of the Universidad … Continue Reading »
