In addition, lava fountains rose ~200 m above the volcano (~6,500 ft a.s.l.). During 20 April at 1720 to 21 April at 0900, lava fountains rose 75-100 m above the volcano (6,100-6,200 ft a.s.l.). Rapid dome growth occurred and by 21 April the lava dome had spread about 250 m E and 200 m SW. On 22 April a "white ash plume" rose ~100 m above the volcano (~6,200 ft. a.s.l.) and on 23 April a "dark gray ash" plume rose to ~150 m (~6,300 ft a.s.l.) and drifted NE.
