Earthlog · Weather and supply
Earthquakes, tsunami alerts, tropical storms and typhoons, official severe-weather warnings, satellite-detected fires, volcanoes and floods on one map, with the rainfall extremes from the Rainfall Monitor as an optional layer. Disasters move food, energy and shipping markets and strain government budgets.
Orange and red warnings from national weather services: windstorms, heavy rain, floods and heat that the tropical-storm feed does not cover.

What each layer is. Earthquakes: USGS magnitude 4.5 and above in the last 7 days; the ring size is the magnitude and a heavier outline means the last 24 hours. Tsunami: bulletins from the two NOAA tsunami warning centres in the last 3 days, most of which say there is no threat. Storms: US National Hurricane Center storms (Atlantic and East Pacific), plus typhoons and cyclones elsewhere from NASA EONET and the UN/EU GDACS system. Fires: NASA FIRMS satellite heat detections over the last 24 hours, grouped into half-degree cells (about 55 km) and sized by total fire power. Volcanoes and floods: open events from NASA EONET and GDACS.
What it is not. Satellite heat detections include crop-residue burning and gas flares as well as wildfires, and cloud can hide fires; low-confidence detections are dropped. A tsunami flag on a quake is USGS's, not a warning. Flood and volcano lists are only as complete as the two sources. Storm positions are the latest advisory and can be hours old. For safety information use the official agencies.
Weather warnings. These are the warnings issued by the national services themselves, not Earthlog's own forecasts. Europe is orange and red warnings from MeteoAlarm (the European weather-warning service) for the countries listed there; the United States is Severe and Extreme alerts from the National Weather Service, combined by type; India is warnings from the National Disaster Management Authority's alert feed, which carries the India Meteorological Department and state authorities, limited to cyclones, heavy rain, floods, heat and cold waves and similar. Ordinary thunderstorm and yellow-level warnings are left out. A warning is a forecast of likely impact, and many end up milder or stronger than first issued.
