Description: From Smithsonian Institution (1978): "A NOAA satellite image on 8 February at 1835 shows simultaneous 60-km plumes emerging from the summits of Shishaldin and Westdahl, about 50 km apart. No plume from Shishaldin is visible in images taken 8 hours earlier and 16 hours later. No ashfall at Shishaldin can be seen in the latter image, but resolution is only 0.9 km and a light or moderate ashfall would probably not be visible." See the Smithsonian website for figures of the satellite images: http://www.volcano.si.edu/world/volcano.cfm?vnum=1101-36-&volpage=var&VErupt=Y&VSources=Y&VRep=Y&VWeekly=Y
