Cleveland (United States) - Report for 11 October-17 October 2017

On 13 October AVO reported that the lava dome in Cleveland?s summit crater, first observed in satellite data on 30 September, had doubled in size during 1-11 October.
The lava dome covered an area of 8,300 square meters, and had approximate dimensions of 115 x 95 m.
The number and intensity of elevated surface temperatures identified in satellite data had declined during the week, possibly indicating slowed or paused dome growth.
A small steam plume was observed in mostly clear web camera views during 15-16 October, and moderately elevated surface temperatures were identified in satellite images on 16 October; these observations suggested continuing dome growth.
The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.
