A dramatic partial lava cone collapse at Merapi Volcano in Indonesia sends glowing molten rock and volcanic debris cascading down the steep slopes on June 30, 2026.
Merapi is one of Indonesia’s most active and dangerous volcanoes, located on the island of Java near Yogyakarta. Its name means “Mountain of Fire,” and it is known for frequent lava dome growth, collapses, explosive eruptions, and fast-moving pyroclastic flows.
In this video, part of the unstable lava dome or cone collapses, triggering a glowing avalanche of hot volcanic material down the flank of the volcano. These collapses are a common hazard at Merapi, where fresh lava can pile up near the summit and then break loose under gravity.
Merapi has produced many major eruptions throughout history, including the deadly 2010 eruption, one of its most significant modern events. Because millions of people live within reach of its hazards, Merapi is one of the most closely monitored volcanoes in the world.
This footage shows why constant volcano monitoring matters. Even a partial collapse can send incandescent rock, ash, and debris racing downslope within seconds.
