Cantwell, Alaska – Three small earthquakes struck Central and Southcentral Alaska within a 20-minute span Wednesday evening, briefly rattling communities from Pedro Bay to Four Mile Road and marking a noticeable cluster in regional seismic activity.
According to the Alaska Earthquake Center, the strongest quake—a magnitude 3.3 event—occurred at 12:34 p.m. AKDT about 50 km west of Cantwell, at a shallow depth of just 3.2 km. Less than a minute earlier, a magnitude 2.8 tremor hit 15 km north of Four Mile Road at 13.3 km depth. Roughly 17 minutes prior, a 2.5 magnitude quake struck much deeper, at 127 km below the surface, 45 km east of Pedro Bay.
So far, no damage or injuries have been reported, though both the Cantwell and Four Mile Road quakes received at least one felt report from nearby residents. Community intensity maps show light shaking consistent with level III on the Modified Mercalli Intensity scale.
While none of the earthquakes individually pose major threats, residents are reminded to check emergency kits, secure loose objects, and know drop-cover-hold protocols in case of stronger aftershocks.
Seismologists continue to monitor the region for further activity.
