Alaska is known for its seismic activity, which includes some of the most powerful earthquakes in history. On Wednesday, a 7.3-magnitude earthquake struck about 55 miles south of Sand Point, prompting widespread concern.
The earthquake occurred at 12:38 p.m. local time and had an epicenter approximately 12 miles beneath the surface. This significant tremor led to an immediate tsunami warning from the National Tsunami Warning Center, although fortunately, no tsunami materialized.
Mayor of Sand Point, Debi Schmidt, shared her firsthand experience of the quake, describing the scene at her home. “I was at home for lunch, and the house was shaking, and things were falling, and cupboard doors were coming open,” she stated. She noted that it was the strongest earthquake she had ever felt, although she reported no significant damage in the area.
Videos showcasing the tremors flooded social media platforms like Facebook, as people documented their experiences. The U.S. National Tsunami Warning Center even released footage captured by a security camera in Sand Point. They emphasized Alaska’s vastness: while some people far away did not feel the quake, others closer to the epicenter experienced significant shaking.
In light of the situation, the National Tsunami Warning Center issued an advisory that affected coastal areas from Unimak Pass in the Aleutians to Kennedy Entrance. Such advisories warn people of the potential for strong currents and dangerous waves, particularly for those near the water. The advisory warned: “Tsunami advisories mean that a tsunami capable of producing strong currents or waves dangerous to people in or very near the water is expected. Significant widespread inundation is not expected for areas under an advisory.”
The city of Kodiak, home to over 5,000 residents, responded proactively by opening shelters in case of emergency. Fortunately, after about two hours, the tsunami warning was lifted, and the threat had passed. The National Tsunami Warning Center later clarified what the cancellation meant, stating: “Tsunami cancellations indicate the end of the damaging tsunami threat.”
As people began to share their relief on social media, the coastal community heaved a sigh of relief. Authorities confirmed that the area is now safe, and no injuries were reported.
Alaska’s seismic activity is a well-known phenomenon, placing it among the most earthquake-prone regions globally. The Alaska Seismic Hazards Safety Commission notes that this state experiences more earthquakes than any other part of the United States.
Historically, Alaska has been shaken by devastating quakes, including the second-largest earthquake ever recorded, which occurred in 1964 with a magnitude of 9.2. Statistically, about 11% of the world’s earthquakes happen in this region, with one earthquake of magnitude 8 or higher occurring approximately every 13 years.
In conclusion, while the 7.3-magnitude earthquake rattled the region and prompted warnings, the local infrastructure and community have shown resilience. With no significant damage reported, residents remain vigilant but grateful that the day ended without tragedy.
