The citizen-seismograph network of RaspberryShake reported a magnitude 4.5 quake in Costa Rica near Golfito, Provincia de Puntarenas, 31 minutes ago. The earthquake hit early morning on Saturday, December 20th, 2025, at 6:43 am local time at a shallow depth of 15. km. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Puerto Cortes (pop. 3,900) located 64 km from the epicenter, Golfito (pop. 6,800) 69 km away, Corredor (pop. 7,100) 88 km away, San Vito (pop. 4,000) 93 km away, Buenos Aires (pop. 11,700) 94 km away, Mercedes (pop. 5,500) 97 km away, Canoas (pop. 4,600) 97 km away, and San Isidro (pop. 34,900) 106 km away.

An earthquake of magnitude 5.4 occurred late at night on Saturday, December 20th, 2025, at 10:58 pm local time near Nemuro, Nemuro-shi, Hokkaido, Japan, as reported by the European-Mediterranean Seismological Centre (EMSC).
According to preliminary data, the quake was located at a moderately shallow depth of 45. km. 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 5.4 earthquake as well. Other agencies reporting the same quake include France’s Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.3, and the German Research Centre for Geosciences (GFZ) at magnitude 5.4.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Nemuro (pop. 31,200) located 68 km from the epicenter, Hamanaka-sakuraminami (pop. 5,500)
