Small earthquake of magnitude 3.0 just reported 72 km southwest of La Ciotat, France

A magnitude 3.0 earthquake near La Ciotat, Bouches-du-Rhône, Provence-Alpes-Cote d'Azur, France, was reported only 9 minutes ago by France's Réseau National de Surveillance Sismique (RéNaSS), considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a very shallow depth of 5. km beneath the epicenter early evening on Tuesday, December 16th, 2025, at 6:03 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 2.7 earthquake.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In La Ciotat (pop. 33,100, 72 km away), the quake was probably not felt.

Small magnitude 3.8 earthquake 26 miles southwest of Kalifornsky, Alaska, United States

A magnitude 3.8 earthquake near Kalifornsky, Kenai Peninsula, Alaska, USA, was reported only 4 minutes ago by the United States Geological Survey, considered the key international and national agency that monitors seismic activity in the US. The earthquake occurred at an intermediate depth of 50 miles beneath the epicenter early morning on Tuesday, December 16th, 2025, at 2:43 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Our monitoring service identified a second report from The Incorporated Research Institutions for Seismology (IRIS) which listed the quake at magnitude 3.8 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.8.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Ninilchik (pop. 880, 11 miles away), Cohoe (pop. 1,400, 24 miles away), Kalifornsky (pop. 7,900, 26 miles away), Anchor Point (pop. 1,900, 27 miles away), Kenai (pop. 7,700, 34 miles away), Soldotna (pop. 4,500, 35 miles away), Homer (pop. 5,500, 38 miles away), and Nikiski (pop. 4,500, 41 miles away), the quake was probably not felt.
