The 1980 eruption of Mount St. Helens was catastrophic due to a combination of factors, including its explosive nature and the presence of a massive amount of volcanic material. The eruption was preceded by a significant earthquake and the formation of a bulging lava dome, which led to a sudden lateral blast that devastated an area of about 230 square miles. Additionally, the eruption released ash clouds that affected air travel and health, while pyroclastic flows and lahars caused widespread destruction to the surrounding landscape and communities. The combination of these events resulted in one of the most significant volcanic disasters in U.S. history.
