Ever wonder which volcanoes are running hot right now? Hotspots gives you a global view.

Hotspots turns NASA satellite observations of thermal activity into a minimalist map of the world's volcanoes.

Each known volcano gets its own little marker, sized according to the relative thermal activity detected by satellites.

Hotspots also checks the Smithsonian's Global Volcanism Program for reported ongoing eruptions. Volcanoes listed as erupting get a little ash plume, so you can tell them apart from volcanoes showing a heat signal alone.

As observations age, the markers fade, so you can see where activity has been spotted recently without drowning in data.
