A powerful 7.2-magnitude earthquake struck near the Alaska Peninsula, causing initial concerns of a tsunami threat. The quake, initially measured at a magnitude of 7.4, occurred late on July 15 evening and was located approximately 55 miles southwest of Sand Point, Alaska. It struck at about 10:48 p.m. local time.
Sirens were sounded in Kodiak, Alaska, and a brief tsunami warning was issued by the National Weather Service in Anchorage, indicating a risk of significant inundation. However, the tsunami warning was downgraded to an advisory and eventually cancelled. While a tsunami was generated, it was no longer considered a threat.
The earthquake occurred along the Alaska-Aleutian subduction zone, known for its frequent seismic activity. The region has experienced several significant earthquakes in the past, including a devastating 8.6-magnitude quake in 1946 and a record-breaking 9.2-magnitude earthquake in 1964.
