Alaska experiences a 4.6-magnitude earthquake

On July 2, 2023, at 11:23 p.m. local time, a 4.6-magnitude earthquake shook the southern part of Alaska, near the city of Anchorage. The quake was felt by many residents, who reported shaking, rattling and swaying of buildings and furniture. Some people also heard loud booms and cracks during the quake.

According to the U.S. Geological Survey (USGS), the earthquake occurred at a depth of 42 kilometers (26 miles) and was centered about 16 kilometers (10 miles) southwest of Anchorage. The USGS said that the quake was caused by the movement of the Pacific Plate, which is sliding under the North American Plate along the Alaska-Aleutian subduction zone. This is one of the most seismically active regions in the world, where large earthquakes occur frequently.

The Alaska Earthquake Center (AEC) said that the quake was followed by several aftershocks, ranging from magnitude 2.5 to 3.5. The AEC also said that there were no reports of significant damage or injuries from the quake, but some minor power outages and gas leaks were reported in some areas.

The AEC advised people to be prepared for more aftershocks in the coming days and weeks, and to check their homes and buildings for any structural damage or hazards. The AEC also reminded people to have an emergency plan and kit ready in case of a larger earthquake or tsunami.

The last major earthquake to hit Alaska was a 7.1-magnitude quake on January 24, 2016, which caused widespread damage and power outages in south-central Alaska. The largest earthquake ever recorded in Alaska was a 9.2-magnitude quake on March 27, 1964, which triggered a devastating tsunami that killed more than 130 people and caused extensive damage along the coast.
