The 1980 eruption of Mount St. Helens did not produce lava flows. It was an explosive eruption that prudiced an ash plume and pyroclastic flows. Pyroclastic flows are avalanche-like masses of superheated ash, rock, and gas. Pyroclastic flows from the initial lateral plast reached as far as 19 miles. Ash blown high into the atmosphere was carried by the wind for thousands of miles.
People were panicked when Krakatoa erupted. The explosion was heard as much as 3,000 miles away, and vibrations were recorded around the world. While people tried to flee, there was no place for them to go, and more than 165 villages were leveled and over 36,000 people were killed. Much of the damage that was done was the result of the tsunami that followed the eruption.
