ShakeOut Amateur Radio Community Intensity Maps
A map for hams by hams
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 ARES LAX Northeast, 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!

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.

🎥 How to use the Amateur Radio Community Intensity Map - Updated on 10/1 ( 16 minutes )
Background: Modified Mercalli Intensity Scale
The Modified Mercalli Intensity Scale
Earthquake intensity measures how strongly the quake is felt and the damage it causes. The U.S. uses the Modified Mercalli Intensity Scale, ranked with Roman numerals from light shaking to severe destruction. It's based on what people experience and observe, not on scientific measurements. Intensity is easier for non-scientists to understand than magnitude since it shows the effects in a specific area. Lower numbers describe how people feel the quake, while higher numbers indicate damage, especially to buildings.
It is important to remember that "Did you feel it?" reports are not damage reports for any given site, but are processed used in aggregate to ascertain damage over a given area.

Data Visualizations
Below are some examples of data visualizations we are experimenting with.
Google Maps ShakeOut Map
This map presents the same data with Cc: SHAKEOUT in a Google Maps format.
This map will be updated manually after ShakeOut, unlike the one above, which updates automatically. We've included it to show how versatile mapping can be when using data from amateur radio reports.
DYFI ShakeOut Reports on PinpointAPRS
In case local internet drops out, net control stations can plot reported Intensities with APRS software.
While the colors are not a great match to USGS colors, an APRS map still provides better visual contrast than the Winlink internal map.
Maps like this can be created with offline tools, making them a resilient option. CSV data can be exported to a spreadsheet, adjusted and, with the help of third party software, turned into a GPX file.
