Mount Lewotobi Laki-Laki Spews Ash
NASA Earth Observatory
In early November 2024, a series of explosive, deadly eruptions occurred at Mount Lewotobi Laki-Laki -- a volcano on the Indonesian island of Flores. A particularly strong eruption on November 3 sent hot volcanic ash as high as 2,000 meters (6,500 feet) into the air around midnight, some of which fell on several surrounding villages.
