Getting started

sisma shows earthquakes around the world as they are reported by four seismic agencies: USGS (United States), EMSC (Europe and the Mediterranean), GeoNet (New Zealand) and JMA (Japan). When several agencies report the same earthquake, sisma shows it once. The list refreshes on its own every two minutes, and you can pull down on the feed to refresh it straight away.

You can use sisma in two ways, with the same account and the same sisma+ subscription:

• On the web at sisma.io/app, on any phone, tablet or computer.
• In the Android app from Google Play, which adds the system share sheet, Google’s account picker and Google Play billing.

The app has five tabs at the bottom (on a computer, in the menu on the left): Feed, Map, Globe, Science and Me.

You don’t need an account to look at earthquakes. An account keeps your saved locations and settings, and is needed for sisma+ and alerts.
