Mount St. Helen does not erupt in any pattern. When it erupted in 1980, scientist had no idea that it was going to erupt because it did not follow a pattern and it did not have very many precursor.
Mount St. Helens famously erupted on May 18, 1980. Smaller eruptions ocurred from 1980 to 1986, 1989 to 1991, and a few times from 2004 to 2008.
The eruption of Mount St. Helens in 1980 was relatively short, lasting for about nine hours. However, the effects of the eruption, including the eruption column and pyroclastic flows, had long-lasting impacts on the surrounding area.
