In brief
The GFZ German Research Centre for Geosciences reported a 5.0‑magnitude earthquake off the coast of southern Alaska at 02:35 GMT, with a shallow 10‑km depth and epicenter at 53.69° N, 162.81° W. A separate report from GFZ/EMSC data indicated the tremor produced weak shaking felt in Arcata, Garberville and McKinleyville. No immediate reports of damage were noted.
A 5.0‑magnitude earthquake struck south of Alaska at 02:35 GMT on Friday, according to the GFZ German Research Centre for Geosciences. The quake, located at 53.69° N and 162.81° W and 10 km deep, prompted warnings of possible surface shaking and prompted the release of a rapid fault‑location report.
Gfzd first identified the event with a shallow depth of 10.0 km, which typically means the seismic energy is released closer to the surface and can be felt more readily by people over a wide area. The coordinates place the epicenter in the Gulf of Alaska, south of Anchorage and along the coast where the Pacific and North American plates meet.
An independent reference from the World Earthquake Report for Thursday, 5 November 2026, based on GFZ/EMSC primary data, notes that the quake occurred at 10:26 pm on November and resulted in weak shaking reported in Arcata, Garberville and McKinleyville. These California towns are located more than 1,200 km away from the epicenter, but the report indicates that the tremor was strong enough to be perceptible in those communities.
Both sources echo the same magnitude and depth figure, but the timestamps differ, reflecting the difference between the event’s initial detection at 02:35 GMT and the time that signals passed through monitoring stations in different regions. The GFZ/EMSC primary data report uses a 10:26 pm time stamp, likely corresponding to the local time in the western United States when the tremor was registered as it travelled across the Pacific.
At present there are no indications of damage or casualties in south‑Alaska or in the California towns that reported weak shaking. Local authorities in Alaska have issued a standard advisory that residents in the region should be aware of the possibility of aftershocks and should keep updated with official seismic monitoring feeds.
South‑Alaska has historically experienced a mix of moderate to large earthquakes due to its position along the Alaska‑Pacific margin. The 2026 event, while moderate in magnitude, falls within the range of earthquakes that the region regularly encounters, and it serves as a reminder of the persistent tectonic activity that shapes the area’s hazard profile.
Global seismological networks such as the GFZ and EMSC provide near‑real‑time monitoring to help communities and governments respond promptly to seismic events. The reporting of this 5.0‑magnitude quake demonstrates how data from multiple observatories is combined to give a fuller picture of the event’s characteristics and its impact on distant communities.
