2026 Great ShakeOut

🗺️ Amateur Radio Community Intensity Map (ARCIM)

🔄 Refresh the page to display the latest incoming entries.

About this Map:

The Amateur Radio Community Intensity Map (ARCIM) plots USGS "Did You Feel It?" (DYFI) exercise reports transmitted via Winlink with CC: SHAKEOUT, mapped by report coordinates.

💡 Teachable Moment:

Pin and bubble colors represent Modified Mercalli Intensity values calculated by the Winlink template. For real-world events, the USGS aggregates an area’s intensity once it receives at least 20 reports—the higher the submission density, the more statistically accurate the data.

Official USGS Scientific Scenario: This page hosts the USGS ShakeOut 2.0 Scenario—a major scientific update modeling a magnitude 7.8 southern San Andreas Fault rupture.
Post-Exercise Map Generation: The USGS Community Intensity Map on this event page is currently a blank baseline. USGS will ingest, filter, and compile exercise reports only after the exercise window concludes (after October 20, 2026).
Real-Time Tracking During the Drill: To view incoming amateur radio reports as they arrive during the drill window (October 10–19), refer to our live ARCIM Map above.
Operational Testing: Amateur radio operators sending Winlink DYFI reports are directly validating secondary and auxiliary communications pathways for USGS scientific response tools.

Amateur Radio Support for USGS

On International ShakeOut Day, October 15, 2026, at 10:15 AM local time, millions of people worldwide will practice earthquake safety. After you “Drop, Cover, and Hold On,” amateur radio operators have a unique role to play: supporting the U.S. Geological Survey (USGS) by submitting Winlink DYFI (“Did You Feel It?”) reports. These reports provide valuable ground-truth data that helps USGS monitor and respond to earthquakes.

By sending your DYFI report via Winlink (Cc: SHAKEOUT; ETO-DRILL;WLNET-OE), you are not only testing our emergency communication readiness, but also contributing directly to a critical USGS data stream that informs science, emergency management, and community resilience.

⁉️ Frequently Asked Questions

Q: What is the Exercise ID for ShakeOut?

The Exercises ID is SHAKEOUT per USGS request.

Q: My group does not live in earthquake country. May we participate?

A: Yes! USGS welcomes Winlink exercise traffic from all parts of the world.

Q: My group is international. May we participate?

A: Yes! USGS welcomes and encourages international exercise participation .

Q: Which timezone is the Time?

A: All times are local time.

Q: I won't be able to send my DYFI Report until I return from work. May I send my traffic later in the day or the next day?

A: Yes! Make sure that you are entering the date and time correctly (October 16, 2005 at 10:16) on the Winlink USGS DYFI form and send your report when you can.

Q: Can I send messages other than USGS DYFI reports to USGS?

A: No! The USGS email in the Winlink message only accepts properly formatted USGS DYFI Reports. All other messages are filtered out.

Q: We are planning an exercise in addition to DYFI. Is that okay?

A: Yes! Shakeout is a great time to test your local and regional radio plans and operations in addition to sending Winlink DYFI Exercise reports.

Q: Would peer-to-peer (P2P) and radio-only (RO) Winlink messages be received by USGS?

A: No. USGS requests that you send your DYFI messages to the official USGS email address the form adds adds automatically.

That means you must use an RMS (Winlink gateway) with an internet connection or Telnet (i.e. the internet) for your DYFI report to be received. USGS does not monitor P2P nor RO.

Q: We are planning a ShakeOut exercise before/after the official ShakeOut date. Is that okay?

A: Yes! You may report your own exercise earthquake event with Winlink DYFI Exercise form submissions. Make sure that your group is aligned on your selected Exercise ID, Date and Time in the Winlink USGS DYFI form . You may customize those.

Q: What is the main goal?

A: Have fun! Shakeout is a great opportunity to learn about disaster preparedness and how volunteer radio operators can help. It is an excellent opportunity to test your radio and group disaster response capabilities.
