The map
The map shows every current event EHW knows about. Each marker is one event, coloured by its category. Nearby events group together until you zoom in. Click a marker for its details, or click a country for its country panel.
Filters
The filter sidebar sits on the left. On a phone, it opens from the tab on the left edge.
- Time window: 1 hour, 6 hours, 24 hours, 72 hours, 7 days, 30 days or everything held.
- Severity: all events, or only those scoring at least 20, 40, 60 or 80 out of 100.
- Categories: turn individual kinds of event on or off.
Layers
Layers add context under the events. All of them are off until you turn them on.
| Layer | What it shows | Source |
|---|---|---|
| Radar | Precipitation radar, United States only | Iowa Environmental Mesonet (NEXRAD) |
| Sea temperature | Sea surface temperature anomaly | NASA GIBS (JPL MUR) |
| Lightning | Lightning strike density over the last 15 minutes; the Americas, the Pacific and the Atlantic only | NOAA nowCOAST (Ocean Prediction Center) |
| Clouds | Infrared cloud imagery every 10 minutes; bright colours are cold storm tops. No Europe, Africa or Indian Ocean | NASA GIBS (NOAA GOES, JMA Himawari) |
| Fires | Satellite fire detections | NASA FIRMS |
| Weather | Areas under a weather warning | The warning agencies |
| Outages | Internet outages by country | IODA |
| Vessels | Ship positions, when this feed is configured | AISStream |
| Fault systems | Major active faults, with an option for minor faults | GEM Global Active Faults |
| Supervolcanoes | Large caldera systems | EHW catalogue |
| Military air | Military aircraft positions, updated every minute | adsb.lol |
A risk heatmap is also available from the search palette.
Strategic layers
Chokepoints, shipping lanes, nuclear sites, and military bases are grouped as strategic layers. They stay hidden until you reveal them.
Sharing a view
The map's address can carry a whole view, so a link opens the map exactly as you left it. Every parameter is optional:

Embedding the map
Another site can show the live map inside its own page. Use the address /embed with the same lat, lon, zoom, time and layers parameters:
<iframe src="https://rift.news/embed?lat=53.5&lon=-113.5&zoom=6" width="100%" height="480" style="border:0" title="Live hazard map"></iframe>The embedded map has no panels. Tapping an event opens it on Rift in a new tab, and tapping a group of events zooms in. Only /embed may be shown inside another site; every other page refuses.
