Merapi volcano (Java, Indonesia): hot pyroclastic flow reported this morning

A pyroclastic flow (hot avalanche of lava particles and ash) descended the southwestern flank of the volcano earlier today, reaching approx. 2000 m distance according to the German volcano news portal vulkane.net. It resulted from a partial collapse of the growing active lava dome at the southwestern rim of the volcano’s summit crater.

The currently active dome is being built on top of the previous dome which fills the central part of the crater. Activity has been increasing in the past days as more magma seems to be rising to the summit. As a result, there are frequent incandescent rock falls and sometimes larger and very dangerous hot avalanches.
