Corroborated Earthquake Event Log
This page lists seismic events detected by the Adam’s Lab Raspberry Shakes that meet one of the following corroboration standards:
- Both Site A and Site B detect the event.
- One site detects the event, and a matching event appears in the USGS alert feed.
- Both sites detect the event, and a matching event appears in the USGS alert feed.
Using two Shakes that are a moderate distance apart, while still relatively close together, helps filter out local movement at each site. Site A and Site B are approximately 1.2 miles apart.
For example, Site A may detect and alert on a truck driving by, but Site B would not detect that truck because it is too far away. In that case, no event is recorded here unless a matching event also appears in the USGS feed.
The confidence level for each detection is calculated based on which sources corroborated it: A+B, Single Site+USGS, or A+B+USGS. It also factors in how closely the observed timing matches the expected seismic-wave arrival. Distant quakes usually trigger a Shake on the S or surface waves rather than the small first-arriving P wave, so the system checks all three and records which wave the detection matched.
The live stream shows all detected events at each site, and I record all of them locally, including screenshots and event details saved to a CSV file. However, they do not appear on this page unless the criteria above are met.
USGS often updates events after automated processing or manual review, sometimes changing details such as magnitude, location, or depth. Because of this, the information shown here may not always match the latest version on the USGS site.
This is an experimental project I put together with AI-assisted vibe coding. Please do not rely on the data here for anything important.
