I like tracking earthquakes and volcanoes.
Yellowstone has been more active, Goddess geyser popping off...magma believed to be just 6 city blocks below ground. Quakes rocking the Ring of Fire from Indonesia to Japan, Alaska, US, Mexico, Central and South America...
And this Fuego volcano in Guatemala has been a fountain for a a few weeks now...watched this live feed last night for a bit...hot lava showing up more dramatically at night...

For earthquakes I check in on this guy, gotta take his quirks in stride though his rants with experts (USGS) are hilarious...especially when the USGS downgrades an earthquake 3 times during one of his broadcasts...but basically his direction flow of plates and energy seems to fairly reliable.
