Field notes
The page displays recent events with intensity, location, magnitude, depth, confirmation source, and map links, alongside articles about catalog differences and magnitude versus felt intensity. It says the service draws on USGS, EMSC, and SGC data, while also describing a coverage gap: one displayed swarm had 13 events in Sismia’s record versus more than 400 in the SGC’s. The iOS and Android apps are marked “coming soon,” so the promised alert and check-in workflow is not confirmed as currently available.
