Magnitude 3.9 earthquake strikes near Puntarenas, Provincia de Puntarenas, Costa Rica

A magnitude 3.9 earthquake near Puntarenas, Provincia de Puntarenas, Costa Rica, was reported only 29 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a very shallow depth of 3. km beneath the epicenter in the morning on Wednesday, May 13th, 2026, at 10:39 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.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 3.8 earthquake.
