Experience the 2025 Magnitude 7.3 Sand Point Earthquake: Insights from the Alaska Earthquake Center

On July 16, 2025, at 12:37 PM Alaska time, a 7.3 magnitude earthquake hit near the Alaska Peninsula, just two years after a 7.2 quake in the same area. This region has seen a surge of seismic activity lately, with multiple earthquakes measuring 7.0 or higher. The quake was located about 55 miles (89 km) south of Sand Point. People felt the tremors as far away as Anchorage and Juneau, though the shaking there was light. In Sand Point, residents reported objects flying off shelves, while in Homer, it felt more like gentle rolling.

Interestingly, the July 2025 quake and the one from July 2023 are both linked to aftershocks from the major 7.8 magnitude Simeonof Earthquake of July 2020. In the first three hours post-quake, over 40 aftershocks were recorded, with the strongest being 5.2. According to the USGS, we might see a magnitude 6 quake within the next week, and smaller tremors are likely to continue.

Right after the quake, the National Tsunami Warning Center issued a tsunami warning but later downgraded it to an advisory. Communities such as Sand Point and Kodiak enacted evacuation plans just in case. Fortunately, no tsunami was reported. However, quick responses to warnings can save lives.

The Alaska Earthquake Center collaborates with local agencies to provide crucial tsunami information and evacuation routes. They encourage residents to check their risk through an interactive map available at tsunami.alaska.edu.

To put things in perspective, while earthquakes appear as mere dots on a map, the areas affected can stretch hundreds of square miles. Understanding this helps communities prepare better for these natural events, which offer both lessons and challenges.

As seismic activity increases, experts urge vigilant monitoring and preparedness. For example, a report from the USGS noted that regions with recent seismic activity have a higher chance of future earthquakes, highlighting the importance of staying informed.
