ShakeOut 2025 – Amateur Radio Support for USGS

On International ShakeOut Day, October 16, 2025, at 10:16 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), 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.

🔗 Instructions for submitting your Winlink DYFI report:

• DYFI Report Instructions

For more information on DYFI and earthquake science, visit the official USGS Earthquake Hazards Program: https://earthquake.usgs.gov .

Let’s show the power of amateur radio in action—support science, improve preparedness, and participate in ShakeOut 2025!

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.

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

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. Learn more about the USGS Modified Mercalli Intensity Scale and the difference between magnitude and intensity.
