This report provides a summary table of dome growth and destruction since 2013 (table 8), and details of continued activity from January through November 2017.
A lava dome was growing at the summit of Cleveland on 4 August 2015.
At 0815 AKST (1615 UTC) on 24 March, a small explosion was detected in both seismic and infrasound (pressure sensor) data.
This event was short-lived and similar to, if not smaller than, recent explosions. Slightly elevated surface temperatures were observed at the summit again during the last week of March.
AVO reported that unrest at Cleveland continued during 11-17 July, though nothing significant was detected in seismic or infrasound data.
Weakly elevated surface temperatures were identified in satellite images on 11 July; meteorological cloud cover prevented views of the crater on the other days.
Not everything over there is fully functional yet, and the internal links still point to this blog, and will for the indefinite future.
So all the old material will be left here for archival purposes, with comments turned off.
Observations in satellite imagery of weakly elevated surface temperatures at the summit continued during 7-9 February and during the last few days of the month.Satellite observations over the next several days indicated continued dome growth.Slightly elevated surface temperatures again appeared in a satellite view on 18 April.Top image is from a FLIR (Forward Looking Infra Red) camera, where warmer colors indicate hotter temperatures (scale is in Celsius); bottom image is a photograph of the summit crater, lava dome, and active fumaroles.AVO crew observed incandescence from the summit crater vent during this overflight. Lava dome extrusion may have been ongoing since early December 2016, when weakly elevated surface temperatures reappeared after the 24 October 2016 explosion.
