I learned a lot of this on channel two last night when some geologists were talking about Mt. Saint Helens. it had all of the different eruptions that i listed above. first in 1980, Mt. Saint Helens blew up leaving the legendary crater in its surface. watching Saint Helens blow up in three different spots looked like three missiles hit it. Saint Helens erupted again in 1983, this time it started dome building. the mountain would slowly ooze black sticky lava that built the dome, after a while it just stopped. finally, in 2004, it erupted again by making spires. the spires then crumbled and started again. the spires stopped 3 years ago.
