Prepare for Earthquake Safety at the Great California ShakeOut

Posted on 10/16/2025
Seismograph For Earthquake

International ShakeOut Day is an annual global earthquake preparedness event held on the third Thursday of October each year. 

This year’s ShakeOut will take place on Thursday, October 16, at 10:16 a.m., when millions across the region will simultaneously “Drop, Cover, and Hold On”. The drill scenario is a "simulated" 7.8 magnitude earthquake striking on the San Andreas fault developed by seismologists and experts. The drill is organized by partners at the Earthquake Country Alliance and reflects very real and massive impacts that such an event would have on our City.

Important guidance for your participation:

  1. How to participate?
    Visit ShakeOut.org/faq for answers to many questions, and ShakeOut.org/howtoparticipate for suggestions, drill manuals, and resources for each ShakeOut participation category. You can also find downloadable audio and video files to assist in the simulation.
     

  2. Promote Broad Participation
    Whenever possible, encourage coworkers to join in the drill at 10:16 a.m. by practicing  “Drop, Cover, and Hold On”. For staff on staggered or overnight shifts, departments may want to hold an exercise at alternate times to ensure participation. You may even want to enhance the “team” aspect of this drill by scheduling a Zoom or Google Meet call at the time.

  3. Register for NotifyLA
    Register your phones and email addresses with NotifyLA.org, the City’s emergency alert system for Citywide updates. 

  4. Promote Use of MyShake App
    Download the MyShake app, the official earthquake early warning app for the western United States, and recommend it to others. Depending on the earthquake's location, the app can often provide real-time alerts before shaking begins.

By participating, we not only enhance our City’s readiness but also recognize that practicing emergency preparedness is the most effective strategy for building a stronger, safer, and more resilient Los Angeles.
