Description: From Reeder (1990): "At 1315LT (=GMT - 9 hours) 19 March 1987, Captain Wallace Niles observed from his Northern Air Cargo DC-6 steam and ash emissions from Mount Veniaminof. The ash plume with steam rose about 200 m above the top of the volcano, and the ash trailed to the SW for up to 40 km. Captain Edward Livingston earlier that day (about 0900LT) observed from his Reeve Aleutian Airways, Inc. YS-11 no ash and only minor steam emissions from the volcano."
