I built Klaxon (https://klaxon.live) as a hobby project — a single static
HTML page that fetches the USGS GeoJSON feed client-side and renders it on
a Leaflet map. No backend, no database, no tracking, no ads. It deploys as
one file on Netlify. It shows M3.5+ earthquakes (1h/24h/7d), with tectonic plate boundaries
overlaid so the spatial pattern is obvious. Popups surface USGS PAGER alert
level, MMI, felt reports and tsunami flags when present. For events in
Japan it links to JMA, since Japanese users think in shindo intensity
rather than magnitude. UI is in English, Japanese and Korean. Deliberately limited: it does not ingest JMA/NOAA directly (CORS + the
static-only constraint), it's not an alerting system, and tsunami support
is just a filter on USGS's tsunami flag — not wave modelling. It's a
situational-awareness map, not a warning service. It's a sibling to an earlier project of mine (an outbreak tracker). Happy
to answer questions about the architecture or the deliberate constraints. |

Isn’t that your backend then?
