Klaxon — Real-Time Global Earthquake Map
Klaxon is a live earthquake map built on the public USGS earthquake feed. It shows magnitude 3.5+ earthquakes worldwide over the last hour, day, or week, with tectonic plate boundaries overlaid so the relationship between seismic activity and plate edges is visible at a glance.
Event details include USGS PAGER alert level, Modified Mercalli Intensity (MMI), felt-report counts, and tsunami flags where the USGS provides them. For earthquakes in Japan, Klaxon links to the Japan Meteorological Agency (JMA), since Japanese users typically reference shindo intensity rather than magnitude.
Klaxon has no ads, no visitor tracking, and requires no account. The interface is available in English, Japanese, and Korean. It is a hobby project built by Asher Malone, and a sibling to the outbreak tracker HantaWatch.
