Great ShakeOUt & Tsunami Evacuation Drill

For international Great ShakeOut Day, Hatfield is holding an earthquake and tsunami evacuation drill to Safe Haven Hill. This is a ideal time to evaluate how long it takes to get out of your building, confirm a route to one of Hatfield’s evacuation sites, and reassess your evacuation plans.

WHEN: Thur., Oct. 20. at 10:20 a.m.

  • For those at Hatfield, you will receive an alert via HMSC Alert text/email (fire alarms will not sound for this event).
  • If you don’t receive a message, don’t wait. Start the earthquake and evacuation drill at 10:20 a.m. – duck, cover, hold, then start walking when it is safe to go. Just follow the tsunami drill signs.
  • For areas east of the Hwy. 101, we will be gathering in the Motel 6 parking lot and then moving up Safe Haven Hill as a group.
  • The disaster cache will be open for viewing and volunteers will be on hand to answer questions. Plan for about 35 minutes to participate.

Everyone in the South Beach area is welcome to join us. 

  • Agency, local businesses and nonprofit personnel are encouraged to participate, but please look for specific information from your leadership.

If you are new to our seismic risk here on the coast, please talk with your supervisor or Cinamon Moffett for more information.  Our goal is for you to feel informed and ready, so please don’t hesitate to ask questions.
