7.3 Earthquake Hits Alaska, Tsunami Alert Issued
A powerful earthquake measuring 7.3 magnitude struck off the southern coast of Alaska on Tuesday afternoon, prompting an initial tsunami warning for several coastal communities. The quake was recorded around 50 miles south of Sand Point, at a shallow depth of approximately 10 kilometers, making it capable of producing seismic sea waves.
Tsunami Warning Briefly Issued and Lifted
Soon after the tremor, authorities issued a tsunami warning for areas between Kennedy Entrance and Unimak Pass. Residents in towns such as Sand Point, Cold Bay, and Kodiak were urged to evacuate to higher ground. However, the warning was downgraded to an advisory within an hour, and later completely lifted after no significant tsunami activity was observed. Only a minor sea level rise of about 2.5 inches was recorded at Sand Point.
Aftershocks Felt, No Major Damage Reported
Several aftershocks followed the main quake, with the strongest reaching a magnitude of 5.4. Despite the intensity of the tremor, there were no immediate reports of injuries or major structural damage. Emergency services remained on alert, and precautionary evacuations were carried out in multiple towns as a safety measure.
High Seismic Risk Zone
The region lies along the Pacific “Ring of Fire,” a highly active tectonic zone prone to frequent earthquakes and volcanic eruptions. Local and federal authorities stressed the importance of early warning systems and community preparedness. Although this event did not result in a disaster, officials reiterated the need for constant vigilance in coastal areas.
