As a Natural Disaster not all of Volcanoes are hot. Some of the largest volcanoes in the Earth are covered with snow or ice. The hot and ice at its peaks leads to very strange natural events – ice towers or ice-filled ice caves. When the volcano erupts, the heat melting ice disappears within minutes. The result is a volcanic flood that drains mud, ash, trees and even car-sized rocks on the slopes.
The ice tower of Mount Erebus, which is higher than 3,500 meters, stretches towards the blue sky. Mount Erebus is in Antartica and is the most active volcano in the south. When it encounters air from the stone near the summit, the steam freezes to form ice towers. An ice tower can reach a height of 15 meters, before it collapses with its own weight.
EXPLOSION IN FROZEN
This bridge was destroyed during a massive flood in Iceland in 1996. A volcanic eruption took place under Vatnajokull, Iceland’s largest glacier that triggered the flood. The water accumulated under the glacier flowed out, creating fractures in the glacier. The flood was 50 meters wide and 5 meters deep. Fortunately, no one suffered from this disaster, but some of Iceland’s largest bridges were destroyed during the flow of water into the sea.
MUD WATER FLOOD
Chile’s Chaiten Volcano erupted in 2008 after a 10,000-year silence. The explosion led to millions of tons of ash, and triggered floods of mud, also called lahar. Mud floods are very dangerous, as they drag everything that comes in their way, and when they stop they become like a giant concrete wall. In the Chaiten eruption, a flood of mud stood in front of the river and changed the course of the river’s water, causing a city to be completely submerged.
AFTER THE DISASTER
Before the eruption of Mount Pinatubo, many major earthquakes occurred, indicating that the disaster was coming. Before the eruption of the volcano, 50,000 people in the area were evacuated. This operation saved many lives. After the disaster, many returned to the area to rebuild their homes, but life in Pinatubo is still unsafe. Every year during the rainy season, the ashes on the slopes of the mountain relax and dangerous mud slippage occurs.
