• M5.2 San Diego earthquake linked to Elsinore Fault renews concerns over major seismic risk in Southern California
  Posted on Apr 17 2025 at 12:05 pm EDT
  
  M5.2 earthquake that struck San Diego County near Julian on April 14, 2025, occurred along the Elsinore Fault Zone, a major strike-slip fault in Southern California capable of producing earthquakes up to magnitude 7.8. The fault runs near densely populated areas including Los Angeles, Long Beach, and Riverside, and its long period of limited activity may indicate an increased potential for a significant seismic event, according to recent research.

• AI-powered monitoring detected over 50 000 earthquakes during intense seismic crisis in Santorini, Greece
  Posted on Apr 15 2025 at 6:41 am EDT
  
  Researchers at the 10th Delphi Economic Forum on April 13, 2025, revealed that the use of advanced machine learning technology enabled them to detect over 50 000 earthquakes in Santorini, some of which occurred before the intense earthquake swarm in February 2025. This early detection enhanced earthquake forecasting and improved warning procedures during the crisis.
