Yeah, doesn't it? I always knew volcanoes did this, but never though of forest fires so much. Hell, the clouds from volcanoes can have lightning in them and even below freezing temperatures. Here's a stunning photo taken from the International Space Station, of Russia's Sarychev Peak erupting earlier this year. Amazing.
