Small explosion at Cleveland volcano on July 20, 2007. This photo, taken from the USFWS research vessel Norseman, shows a small ash cloud rising a few thousand feet above the summit and drifting downwind. This type of intermittent explosive activity is likely characteristic of the current level of unrest at Cleveland. Such small ash clouds can easily go undetected on satellite imagery.
