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: PCARES; ETO-DRILL), 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.

📢 The Emcomm Training Organization Posts Results for the "Great ShakeOut" Exercise

See the ETO web site: :: Winlink Thursdays :: EmComm-Training.org™ ::

Special thanks to Bob KM6SO and ETO for his excellent work compiling the results and providing individualized feedback.

We recommend everyone take a moment to look through the ETO results and analyze their feedback. It is a great opportunity to learn!

The Amateur Radio Community Intensity Map plots "Did you feel it?" reports sent by radio operators with Winlink with CC: SHAKEOUT. It uses the report latitude and longitude for location.

Teachable Moment: The bubble colors represent Mercalli intensities calculated in the Winlink form. Note that the USGS calculates Mercalli intensities for an area when there are at least 20 reports. The more reports submitted for a specific area, the more accurate and significant the intensity measurement becomes.

⚠️ Note: ARCIM charts the data it receives from the Winlink DYFI CSV. However, Winlink seems to have a problem exporting PAT reports to CSV. ARCIM can obviously not map any data that is missing in the CSV.

RATPAC Presentation: 2026 Amateur Radio ShakeOut – Preparedness for Everyone!

On Wednesday, September 23 the Radio Amateur Training Planning and Activities Committee (RATPAC) hosted the "2026 Amateur Radio ShakeOut – Preparedness for Everyone!" presentation.

Earthquake safety and all-hazards preparedness start with practice! In this session, discover how ham radio operators around the globe can participate in the upcoming Great ShakeOut drill using Winlink and digital messaging. Presenters Oliver K6OLI (LAXNORTHEAST) and Bob KM6SO (Emcomm Training Organization) will guide participants through the importance of all-hazards emergency readiness and provide a step-by-step walkthrough on how to complete and transmit:

• A Winlink USGS "Did You Feel It?" (DYFI) report

• The 2026 ShakeOut Preparedness Survey

• The 2026 ShakeOut Preparedness Quiz

Whether you operate online or completely offline, learn how your station can contribute vital data to the United States Geological Survey (USGS) while honing your EmComm skills.

Date: Wednesday, September 23, 2026, 9:00 PM ET / 8:00 PM CT / 7:00 PM MT / 6:00 PM PT / 01:00 UTC

⁉️ 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.
