Discovery News."We can all agree that volcanic explosions are filled with awesome. But get too close, and you're toast. The camera monitoring Sakurajima Volcano in southern Japan was definitely well within the danger zone when it snapped this stunning sequence last month of a visible shock wave propagating out from an explosion in the Showa crater:
Notice the rocks and boulders being flung out from the ash cloud at high speed; had a human been present, s/he would've probably got a nasty bonk on the head, at best. But this is a tiny outburst by Sakurajima's standards -- it used to be an island until a 1915 eruption sent lava pouring into Kagoshima Bay and connected the volcano to mainland Kyushu."
