Dr. F. Ramón Zúñiga, from the Centro de Geociencias, Universidad Nacional Autónoma de Mexico, outlines the 19 September 2022 Mw7.7 Coalcomán, Mexico earthquake for the last Earthquake Watch of the year. On September 19th, barely one hour after the national drill commemorating the damaging earthquakes of September 19th, in 1985 and 2017, another strong earthquake was widely felt in Mexico. It cause ...[Read More]

Scientists from Géoazur (CNRS/IRD/Observatoire de la Côte d’Azur/Université de la Côte d’Azur), Karlsruhe Institute of Technology, Instituto Geofísico / Escuela Politécnica Nacional (IG-EPN, Quito), Instituto Oceanográfico de la Armada del Ecuador ...[Read More]
Global seismoacoustic waves from the Hunga eruption (Tonga)
Jelle Assink, Senior Geophysicist at KNMI, takes us through the details of the various kinds of waves produced by the Hunga eruption in Tonga earlier this year… On January 15, 2022, a powerful volcanic eruption occurred in the Tonga archipelago in the Pacific Ocean when the submarine Hunga volcano exploded around 04:15 (UTC). This explosion marked the climactic end of an eruptive phase that ...[Read More]
Vibrant ecosystems: Of rumbling elephants and seismic wildlife monitoring
Tarje Nissen-Meyer – Associate Professor of Geophysics at Oxford University, UK – shows how seismic signals of stomping in the savanna can be used to track elephants and other wildlife in Kenya. Our planet is at unrest. From butterfly wings to rock gigs, typhoons and megathrust earthquakes, mechanical wave disturbances permanently penetrate the Earth system across many orders of magnit ...[Read More]
