Clouds Glow: the eruption that flows like clouds clouds rolled Glow is a suspension of fine material that is exhaled by a volcano and is a dense mixture of gas vapor and fine material before, with a temperature greater than 600 ° C. At Mount Merapi, Central Java incandescent cloud is also called "wedus trash" happens because the release of gases and fine material thrown from a burning dome avalanches (Merapi Type).
