The SW lava dome produced 5 lava avalanches that traveled as far as 2 km SW down the Bebeng drainage, 37 that traveled as far as 2 km SW down the Krasak drainage, and 46 that traveled as far as 2 km W down the Sat/Putih drainage. Small morphological changes to the SW lava dome resulted from lava effusion and minor collapses.
The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 3-7 km away from the summit, based on location.

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

At around 05:59 local time early this morning, a hot avalanche, known as pyroclastic flow, detached from the active southwestern lava dome at the summit crater.
The extremely dangerous, fast-moving turbulent flow consists of a mixture of hot rock fragments of the lava dome, volcanic gasses and ambient air. It traveled through the Kali Boyong ravine on the southwestern flank. It also produced white-to-grey ash plumes, so-called phoenix clouds, separating from the block-and-ash flow.
Pyroclastic flows are typically formed when the accumulated lava masses at the summit crater, known as the lava dome, become too large and suffer smaller or larger grav…Open article
