Mount Lewotobi Laki-laki erupted on Tuesday and Wednesday (June 17 and 18), unleashing gigantic ash plumes and showering villages with volcanic debris.

Indonesian Authorities raised the eruption alert to the highest level and expanded the danger zone to 8 kilometers (about 5 miles) from the crater. The ashes expanded into a mushroom-shaped ash cloud that could be seen from the cities located 90 kilometers (about 56 miles) to 150 kilometers (nearly 93 miles) from the mountain.
