and deep explosions. This tubular phase lasted until the 20th, 
the emission of pyroclastic material ? < a s so pres t tnet a 
part of the southeast rim of the crater rose about 20 meters in 
height, nearly attaining the altitude of the east peak.. The silent 
eruption that followed continued nearly to the end of the month, 
gradually giving may to a gaseous eruption, with its characteristic 
emission of white vapors. 
Of the three vents in the crater described by Kennedy, 
the south? est one contributed most of the ejecta during the fey 
13-20 eruption, whereas the gaseous activity at the eno of M ay 
came from the small central vent, causing it to become larger at 
the expense of its neighbors, both of which were quickly stopped 
up and covered. During the first days of June the east p< 
became incrusted with white salts. The southwest vent blew o en 
again, emitting vapors that were generally more yellowish. thin 
those from the central vent. Some 15 meters -outhwest of the 
central vent and about 5 meters lower, a small new vent opened,

Another cycle began on June 11, starting with & tubular 
eruption marked by typical periodic explosions and accompanied 
i y s fall of ash, scoria, and bombs, but becoming silent on 
June 18; occasional puffs of vapor occurred with weak rolling 
explosions. Then on the 21st the gaseous stage reappeared

strongest ones some rocks were thrown out. The tubular activity
