Earthquake Details
The U.S. Geological Survey (USGS) reported that the quake occurred approximately 87 kilometers south of Sand Point at a depth of 20 kilometers. This seismic event was recorded at 4:37 PM EDT on Wednesday, raising immediate concerns about potential tsunami threats.
“It is the most significant event since we have been having monitoring equipment at Mount Rainier. We have to remember Mount Rainier is really old. We’ve only been monitoring it for 40, maybe 50 years now. So just because it’s the most significant one we’ve seen on equipment doesn’t mean this hasn’t happened in the past prior to 2009,” said Alex Iezzi, research geophysicist at USGS Cascades Volcano Observatory.
Affected Areas and Safety Precautions
The following areas are set to be affected due to the earthquake, as per the National Weather Service (NWS). Residents have been urged to seek higher ground immediately:
- Homer area (Kenai Peninsula Borough)
- Sand Point and King Cove (Aleutians East Borough)
- Unalaska (Aleutians West Census Area)
- Unimak Island, including the Scotch Cap area
