A low-level plume that rose to an altitude of 3.5 km (11,500 ft) a.s.l. was observed by a web camera on 6 June. A strong sulfur odor was reported by observers in Nikolski (75 km E). Clouds prevented views of the volcano on 7 June. Minor deposits of ash near the summit crater were observed in satellite images during 9-10 June and elevated surface temperatures were detected during 11-12 June.

Cleveland volcano (Alaska) activity update: small explosions, destruction and re-growth of small lava dome
Based on analyses of satellite images, AVO reported on 4 May that the small lava dome recently emplaced in Cleveland's summit crater had been destroyed late in the previous week, but the explosion was too small to be detected by distant infrasound and seismic networks. A small new dome was extruded following the explosion and was the fifth dome to be observed in this eruptive episode which began in July 2011. During 4-5 May two small explosions were detected. ... read all

AVO reported that a small explosion from Cleveland was detected at 0112 on 4 April by distant seismic stations and infrasound arrays. Weather conditions prevented the detection of a possible eruption cloud in satellite images or by visual observation of the summit. Observations the next day revealed a thermal anomaly and that the 70-m-diameter lava dome had been destroyed by the explosion. This was the third lava dome that was erupted and subsequently destroyed by explosive events since the eruption began in July 2011. ... read all
