The intent of the Amateur Radio Community Intensity Map (ARCIM) is to show radio operators their own and their groups' "Did you feel it?" (DYFI) reports in an easy to use format.
All amateurs can add their entries to this map by submitting Winlink DYFI reports To: SHAKEOUT on 10/17 at or after 10:17 local time.
This map project is a collaboration of LAXNORTHEAST, San Diego ARES , Ventura ACS/ARES, San Joaquin Valley Section and the IEEE MOVE Project Radio Club and is provided for the whole amateur radio community.
We would like the to thank ShakeOut and the Earthquake Country Alliance for their encouragement of the ARCIM project!
We will update this page with additional information, ShakeOut Tips and more until 10/17. Check back often!
*Note: Map locations derived from DYFI report latitude & longitude. Therefore report locations may vary from street addresses. Please keep the FormData.txt file attached to the DYFI message for proper mapping.

This is the USGS 2024 ShakeOut Scenario Community Intensity map. It plots the Amateur Radio DYFI reports received by USGS for the 2024 SHAKEOUT. Click on the map to view a zoomable and detailed map or follow this link.
Special thanks to V. Quitoriano and Dr. D. Wald of USGS for sharing this map!

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.
Oliver K6OLI presents the results of the ARCIM and facilitates a lively discussion and sharing of experiences.
