Treacherous Volcano’s

The largest explosion in the earth this century occurred June 6-9, 1912, at Novarupta on the Alaska Peninsula.

More than a foot of volcanic ash from this enormous explosion collapsed roofs in the community of Kodiak, 100 miles away, and choked rivers and streams, devastating Alaska's fishing industry. Several villages along Alaska's southeast coast were deserted eternally.

The eruption of Mount Pinatubo, Philippines, on June 15, 1991, blasted about 1 cubic mile of ash and rock into the atmosphere. Avalanches of hot ash, gas, and wreckage of pumice roared down the spur, filling valleys with as much as 600 feet of volcanic fragments.

 A small eruption of the Nevada del Ruiz volcano in Colombia on November 13, 1985, melted as regards 10 percent of the volcano's ice cover, leading to a gigantic mudflow that inundated the city of Armero and killed further than 23,000 people.
