PVMBG reported that during 1-11 February the volume of the lava dome in Merapi?s summit crater was about the same as the previous week?s estimate of 461,000 cubic meters, and there were no apparent morphological changes.
Most of the extruded lava fell into the upper parts of the Gendol River drainage and the SE flank.
On 7 February a pyroclastic flow traveled 2 km down the Gendol drainage.
The Alert Level remained at 2 (on a scale of 1-4), and residents were warned to remain outside of the 3-km exclusion zone.
