Merapi volcano news & eruption updates

Merapi volcano (Central Java, Indonesia) activity update: summit dome collapsed

Sunday Oct 21, 2012 10:05 AM | BY: T

The summit dome who occupied the summit crater partially collapsed at an unknown date but very recently (probably in October because it was still seen in Sep).
The reason for its disappearance is not clear as the event was not noticed by local volcanologists. An article in Jakarta Post article mentions that according to volcanologists, rain was not a likely cause as there has been very little. Nor was any unusual activity (such as deformation, seismic activity etc) recorded recently.
This dome collapse should serve as a warning that even during times of repose, the volcano is able to produce dangerous activity in form of debris avalanches and lahars, as the rainy season approaches.

During a recent visit to the crater of Merapi 26-27 May, our friend Øystein from Jakarta could clearly observe a new lava dome that is slowly building up inside a depression of the summit crater. The dome is not very active yet, but has a very small glowing part of lava at the western end. This activity is consistent with the latest data from the Merapi volcano observatory reports on seismic levels at the time. [more]
