On a recent visit to Japan, alien landscape photographer Martin Rietze captured some spectacular images of Sakurajima volcano in Kagoshima prefecture. They are absolutely crazy - I never imagined lightning and lava could react together like this. (I originally saw them on PinkTentacle.com) It's worth checking out Rietze's website - he has been to some extraordinary places.
