The small 5 x 7.5 km island of Ekarma lies 8.5 km north of Shiashkotan
Island along an E-W-trending volcanic chain
On 10 August scientists observed a vigorous steam plume from Ekarma that rose to an altitude of 1.8 km (5,900 ft) a.s.l.
. On 24 August scientists visited Ekarma Island and observed continuous vigorous gas emissions from a new vent located
on the S flank, about 250 m below the summit. The flanks had been blanketed by a layer of fine ash with a thickness
exceeding 5 cm in the vicinity of the vent. Two recent lahar deposits were seen on the S flank.
Based on their observations, SVERT speculated that a small eruption may have occurred between early June and late
July 2010. Ekarma does not have a seismic network; satellite image analysis and infrequent ground observations
are the primary tool for monitoring many of the Kuril Islands volcanoes.
