Small magnitude 3.6 quake hits 38 miles west of Anchor Point, Alaska, United States early evening

An earthquake of magnitude 3.6 occurred early evening on Saturday, December 6th, 2025, at 6:18 pm local time near Anchor Point, Kenai Peninsula, Alaska, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at an intermediate depth of 68 miles. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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 Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 3.7 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.7.
According to preliminary calculations, we do not expect that the quake was felt by many people and did not cause any damage. In Anchor Point (pop. 1,900, 38 miles away), Diamond Ridge (pop. 1,200, 49 miles away), and Homer (pop. 5,500, 50 miles away), the quake was probably not felt.

Earthquake data:
Date & time: Dec 6, 2025 06:18 pm (Anchorage time) local time (7 Dec 2025 03:18 GMT)
Magnitude: 3.6
Depth: 108.73 km
Epicenter latitude / longitude: 59.83°N / 152.92°W (Kenai Peninsula, Alaska, United States)

Small 3.7 quake hits near Ambato, Tungurahua, Ecuador

A shallow magnitude 3.7 earthquake was reported in the afternoon near Ambato, Tungurahua, Ecuador.
According to the European-Mediterranean Seismological Centre (EMSC), the quake hit on Saturday, December 6th, 2025, at 5:54 pm local time at a shallow depth of 20. km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 Institute of Geophysics of the National Polytechnic School in Quito (IGEPN) which listed the quake at magnitude 3.9.
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 Pelileo (pop. 16,600) located 2 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Ambato (pop. 387,300) located 13 km from the epicenter, Banos (pop. 9,500) 14 km away, Pillaro (pop. 7,500) 18 km away, San Miguel (pop. 10,800) 32 km away, Guano (pop. 12,700) 33 km away, and Pujili (pop. 16,200) 45 km away. In Machachi (pop. 25,700, 91 km away), the quake was probably not felt.

Magnitude 4.8 earthquake strikes near Pátrai, Achaea, West Greece, Greece

UPDATE: the quake was later downgraded to magnitude 4.6.

Original report:

Just 21 minutes ago, a 6.4-magnitude earthquake struck near Pátrai, Achaea, West Greece, Greece. The tremor was recorded late at night on Saturday, December 6th, 2025, at 10:48 pm local time, at a shallow depth of 10. km below the surface.

The event was filed by the German Research Centre for Geosciences (GFZ), the first seismological agency to report it.

Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 4.8.

Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.

Moderate shaking probably occurred in Pátrai (pop. 168,000) located 24 km from the epicenter, Aigio (pop. 20,400) 24 km away, Amaliada (pop. 16,800) 58 km away, Pyrgos (pop. 22,400) 61 km away, and Agrinio (pop. 46,900) 74 km away.

In Athens (pop. 664,000) located 160 km from the epicenter, the quake should have been felt as light shaking.

VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you’re in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.

Magnitude 4.7 earthquake strikes near Pátrai, Achaea, West Greece, Greece

A magnitude 4.7 earthquake near Pátrai, Achaea, West Greece, Greece, was reported only 12 minutes ago by the National Observatory of Athens (NOA), considered the main national agency that monitors seismic activity in Greece. The earthquake occurred at a very shallow depth of 5. km beneath the epicenter late at night on Saturday, December 6th, 2025, at 10:48 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 Kandilli Oservatory and Earthquake Research Institute in Istanbul (KOERI-RETMC), which listed it as a magnitude 4.7 earthquake as well. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.9, the German Research Centre for Geosciences (GFZ) at magnitude 4.8, The Aristotle University of Thessaloniki Geophysical Lab. (AUTH) at magnitude 4.6, The Seismological Laboratory of the University of Athens (UOA) at magnitude 4.7, and the citizen-seismograph network of RaspberryShake at magnitude 4.8.
Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.
Moderate shaking probably occurred in Kalavryta (pop. 1,600) located 6 km from the epicenter.
In Diakopto (pop. 5,600) located 24 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Aigio (pop. 20,400) located 26 km from the epicenter, Pátrai (pop. 168,000) 37 km away, Pyrgos (pop. 22,400) 65 km away, Amaliada (pop. 16,800) 65 km away, Argos (pop. 22,200) 74 km away, and Corinth (pop. 30,200) 80 km away.
