Klaxon shows where significant events are happening right now, on one map, in one place — without the friction of jumping between government bulletins, news feeds, and academic data portals.

The current release ingests the public USGS earthquake feed and displays events of magnitude 3.5 and above from the last hour, day, or week. Markers are sized and coloured by magnitude. Click a marker for depth, time, coordinates, and a link to the USGS detail page. The amber overlay traces the world's tectonic plate boundaries, so it's immediately visible that most earthquakes follow them.

Data refreshes every minute. Nothing is stored server-side; the map talks directly to USGS in your browser.
