Mount St. Helens, 30 Years Ago


Yesterday it was 30 years ago that Mount St. Helens in Washington state, USA, erupted after a series of earthquakes below the volcano's peak.

It released a mushroom cloud of gases 63,000 feet high and sent a lavalike mixture of glass, gas, and ash down the mountainside at speeds up to a hundred miles per hour, killing sixty people, decimating several native animal populations, and destroying $500 million worth of timber.
