Lava dome on top of Mount Merapi collapses
A lava dome that formed on top of Mount Merapi following its 2010 eruption has collapsed, prompting volcanology officials to issue a warning on Friday of a possible deadly cold lava stream on the mountain slope.
Lava flows from Puu Oo have reached the abandoned Royal Gardens subdivision, about 4.4 miles southeast of the crater, scientists at the Hawaiian Volcano Observatory report.
