Near-real-time earthquake notifications
SeismoWatch monitors the USGS global feed around the clock and notifies your phone after a matching earthquake appears — for the area and magnitude you care about.
Pick a region on the map. Only quakes inside your box reach you — antimeridian-aware, so the Pacific rim works too.
Choose a minimum magnitude. Skip the constant M2 chatter and only hear about the ones that matter to you.
After a matching event appears in the USGS feed, a persistent connection delivers the notification without waiting for an email or website refresh.
Grab SeismoWatch for Android. It's a lightweight companion to this alert service.

SeismoWatch is a near-real-time, post-event notification service. It sends information after an earthquake is published by USGS; it is not an earthquake prediction or early-warning system and should not be relied upon as an emergency service. Learn how the systems differ.
