"No satellite images available after the time of the explosion, so uncertain if minor ash cloud generated, but unlikely.
"Similar such explosions may continue without warning, and may produce minor ash clouds that are not expected to extend much beyond the volcano, but could produce local fallout on the flanks of the volcano. AVO has received no reports of activity from local observers." (AVO/USGS)
