If there was something coming, there is nothing to show at this point in time, he says.Learning from the PastStill, the level of recent underground activity fuels speculation about the intensity of an eruption. Today, scientists are trying to predict how this ticking time bomb will explodeor fizzle out. Because these lavas tend to plug up volcanic plumbing, gas pressures can more easily build up to high levels, often resulting in explosive eruptions. Almost 40 years ago, it was home to one of the biggest volcanic explosions in U.S. history when Mount St. Helens erupted. It depends. When a volcano is dormant (the French word for sleeping), this means that it has not erupted in some time, but that it is due to blow again.
