Welcome to your seismic update from across the state for the week of Oct. 15, brought to you by the Alaska Earthquake Center, where we monitor ground shaking 24-7.
Over the past week, we recorded about 340 seismic events. The largest was a magnitude 4.3 on October 11 in the western Aleutians. Five events were reported as felt.
This week, we’ll focus on Alaska’s annual earthquake emergency drill, the Great Alaska ShakeOut. Across the state on October 16 at 10:16 a.m., people and organizations will test their readiness for a large, damaging earthquake. The ShakeOut is the perfect chance to discuss and practice earthquake preparedness in your home, classroom, or business.
The Shakeout happens on the third Thursday of October. The drill originated in California to commemorate the October 17, 1989, magnitude 6.9 Loma Prieta earthquake, which caused 63 deaths, more than 3,700 injuries, and $10 billion in damage. Today, the Shakeout has expanded to earthquake-prone areas across 24 U.S. states and territories, and internationally.
Before an earthquake, you can prepare by securing your space. This could mean making sure there aren’t heavy picture frames over your bed or couch, anchoring large furniture and appliances to the wall, or creating a safety plan. Visit ready.gov for tips on what to pack in your emergency kit.
During an earthquake, don’t try to leave your building. Walking is especially hazardous during strong shaking. Instead, practice Drop, Cover, Hold: drop to the floor, take cover under a desk or table (if possible) to protect yourself from falling objects, and hold on until the shaking stops.
