Anchor Point, Alaska – A deep, moderate earthquake shook parts of the Kenai Peninsula on Tuesday night, giving residents west of Anchor Point a brief jolt as the region experienced a 4.2-magnitude tremor.
According to the U.S. Geological Survey, the quake struck at 21:57 UTC on Tuesday roughly 56 kilometers west-northwest of Anchor Point at a depth of about 99 kilometers. No damage reports have been filed, and no residents have submitted shaking responses so far.
The offshore location and significant depth helped limit surface impacts, though light vibrations were possible across the southern Kenai Peninsula, including communities such as Ninilchik, Nikolaevsk and Homer. Emergency managers in the area noted that events of this size rarely produce structural issues but can serve as reminders of the region’s active seismic zones.
Alaska averages many moderate earthquakes each year, particularly along the Aleutian and Cook Inlet fault systems. Local agencies encourage residents to review their emergency kits, secure top-heavy furniture and keep phones charged in case aftershocks occur.
While no additional alerts have been issued, USGS will continue to monitor the area for minor follow-up activity. Residents who felt the quake are encouraged to file a report to help refine future seismic assessments.
