Your regions, your alert rules
You care about specific places — your hometown, a coast you're watching, a region you work in. Drop a pin, draw a shape, or paste GeoJSON, and that place gets its own alert rules. Everything else fades out.
Pick, Draw, or ImportClick for a circle, draw a polygon point by point, or paste raw GeoJSON if you're that kind of person. All three work.
Your Rules, Per PlaceYour beach house cares about tsunamis at any level. Your city apartment only wants M5+ earthquakes. Set different thresholds for each place, each domain.
Focus & FilterTap a place and the whole feed narrows down to events inside it. Live pills count what's happening there right now, per domain.

Seismic Intelligence
Three agencies, one unified feed
An earthquake hits and three agencies report it separately. We pull from all of them, figure out it's the same event, and show it to you once — with the best data from each.
Smart Dedup & GroupingSame quake from three agencies? Merged. Aftershock swarm in one area? Grouped. You see each earthquake once, and related events clustered together.
Live WebSocketEarthquake just happened? It's on your map before you finish reading this. EMSC streams events live, and the connection heals itself if it drops.
... basically every earthquake, once, from everyone who detected it.
Volcanic Monitoring
Lava lakes, seen spilling from space
Three agencies watch volcanoes, and we merge all of them. But the real trick? We scan satellite infrared for thermal anomalies and match them to known summits — so you can see a volcano warming up before anyone puts out an alert.
Thermal ScanningSatellites see heat before anyone calls it an eruption. We match every infrared hotspot to the nearest known summit and score how worried you should be.
Cross-Source Alert LevelsThree agencies track the same volcano? You get one entry with the highest-confidence alert level. Normal, Advisory, Watch, Warning — no noise, no duplicates.
GVP Weekly ReportsThe Smithsonian publishes weekly bulletins on every volcano that's acting up. They're right here, drill down to the full text.

Cyclone Tracking
Full storm anatomy, from eye to forecast
Where has it been, where is it going, and how big is the danger zone? We pull 8 layers from NHC and JTWC and lay the whole storm out on the map — track, cone, wind rings, everything.
Dual Track LinesSolid line for where it's been, dashed line for where it's heading. One glance and you know the full story.
Uncertainty ConeThe official "it could go anywhere in here" zone, drawn right on the map. Storms that cross the date line? Handled automatically.
Wind Radii ContoursThree nested rings showing where tropical storm, 50-knot, and hurricane-force winds reach. Click any ring to see exactly what you're looking at.
... basically the entire storm, decomposed on a map.
Tsunami Alerts
Instant alerts, pulsating clarity
Tsunami warnings don't wait, and neither do we. NWS and GDACS alerts show up as pulsating markers you can't miss, and if a big earthquake triggers a tsunami flag, that comes through the seismic feed too. When the alert expires, it cleans itself up.
Pulsating MarkersBig red rings that pulse on the map. The worse the threat, the faster and brighter they pulse. You won't scroll past one by accident.
Auto-ExpiryEvery alert has a clock. When it expires, it's gone — no stale warnings cluttering your map.
Dual-Source MergeNWS covers the Pacific and Hawaii, GDACS covers the rest of the world. You get one clean timeline, no duplicates.

Wildfire Intelligence
Every hotspot, tracked from orbit
NASA's satellites spot hotspots from space, we spot them and spit them on your map. Tens of thousands of hotspots, color-coded by how hard they're burning, plus official fire perimeters so you can see the actual boundaries.
50,000+ HotspotsEvery fire detection NASA FIRMS picks up, rendered without breaking a sweat. Zoom out and they cluster. Zoom in and you see each one individually.
Intensity ClassificationNot all fires are equal. Bigger, hotter fires get bigger, brighter markers. Filter out the small stuff and focus on the ones that matter.
NIFC PerimetersSatellite hotspots tell you where it's burning. NIFC perimeters tell you how far it's spread. Both on the same map, no overlap.
... basically every fire the satellites can see, in your browser.
Weather Monitoring
Three sources, one weather picture
Every region has its best weather authority. Europe? EUMETNET. The US? NOAA. Everywhere else? WMO. We pull from all three and figure out who knows that area best — no duplicates, no gaps.
Best Source, EverywhereLooking at France? You get EUMETNET. Looking at Texas? You get NOAA. Looking at Japan? You get WMO. The right authority for every square kilometer, automatically.
Severity on the MapAlerts painted as colored regions — red for extreme, orange for severe, yellow for moderate. One look and you know where the trouble is.

Global installations, mapped and classified
OpenStreetMap, US Department of War records, and Covert Cabal's curated research — three sources that don't talk to each other. We pull from all of them, merge anything within 5 km, and give you one clean map.
Two-Tier DiscoveryFirst pass grabs the bases, airfields, and naval stations. Second pass adds fortifications, bunkers, and restricted zones. Both cached at the edge so it's fast.
No DuplicatesSame base in OpenStreetMap and the DoW registry? We know. If two entries are within 5 km, they become one. You see each installation once.
