What is Klaxon?

Klaxon is an independent, real-time tracker for global emergency events. The first release covers earthquakes worldwide. Tsunamis, wildfires, and armed conflicts are next.

What it does

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.

What's coming

Each emergency type has its own authoritative feed. Klaxon's plan is to layer them onto the same map and unify the visual language so a fire, a quake, and a tsunami warning feel like part of one system rather than three different products.

• Live
  Earthquakes
  USGS feed, M3.5+, refreshed every minute. Plate boundaries overlaid.
• Live
  Tsunami sources
  Filter on earthquakes USGS has flagged as tsunami-generating. Wave arrival times from NOAA coming later.
• Soon
  Wildfires
  NASA FIRMS active-fire detections from MODIS and VIIRS satellites.
• Later
  Armed conflicts
  ACLED-style geolocated incident reporting, with a strong editorial filter on source quality.

Why build this

When something serious happens — a quake near a major city, a wildfire near a populated area, a tsunami advisory — the first few minutes of looking for information are usually frustrating. The authoritative data exists, but it's spread across agency websites that load slowly, use unfamiliar interfaces, and rarely talk to each other. News coverage fills the gap, but with the trade-off of speculation and inconsistency.

Klaxon's job is to be the single map you check first. Fast, sober, accurate. Authoritative sources only. No ads, no tracking, no signup. If a category of event isn't on Klaxon yet, that's fine — it'll be added when the right primary feed is wired in, not before.

Who makes it

Klaxon is built by Asher Malone — based in Sydney, Australia. It's a hobby project, not a company. There's no team, no funding, no business model: just one person who finds it useful to have a single, calm map of what's going on in the world. Klaxon shares its design system and codebase pattern with HantaWatch, an outbreak surveillance tracker I built earlier this year for the MV Hondius hantavirus outbreak.

Klaxon is a single static page deployed on Netlify. The map talks directly to USGS in your browser — there's no Klaxon backend, no analytics, no tracking, no ads. If something looks wrong or breaks, that's on me; if it's quietly working, that's the goal.
