Epicentral is a network-based educational application that displays lists and maps of earthquakes that occurred during the last day, week, or month. This version runs on iPhones, iPads, and Macs (as an iPad App) but requires iOS 26+ and macOS 26+. The data are served by the U.S. Geological Survey or the European-Mediterranean Seismological Centre (and three other seismological organizations). List updates take at most a few 10s of seconds. For each event, a summary of the event’s properties and relationship to nearby recent seismicity is presented. When using the USGS feeds, a link to the event-specific USGS earthquake information page is available. Several historical earthquake catalogs (sourced from the US Geological Survey) are included to provide context for more recent earthquakes. These catalogs can be used to put more recent activity in context.
