What Next From Iceland's Volcano?

How long will this disrupting eruption last?

As Europe writhes in agony, millions of people are asking this question, desperately praying for relief from the paralysis of the airline industry caused by an Icelandic volcano.

This eruption is a perfect storm, a combination of wind and ice conditions that has turned an ordinary eruption into a crisis. Last month, the same volcano erupted harmlessly. But last week, magma found a second pathway to the surface, this time beneath a glacier. When hot magma touched ice, it instantly created a burst of steam and produced glassified silicates. The sudden expansion of steam created a colossal explosion that sent billowing clouds of glassified silica ash three to five miles into the air over Europe. The ongoing eruptions of the volcano, which continue unabated, are caused by a series of steam explosions as magma continues to encounter glacial ice.

There are three scenarios for what could come next:

1) The best scenario is that over the next few days either the magma spends itself or the ice finally melts. Without ice, the eruption will become an ordinary one. Scientists have tried to send airplanes to the volcano to analyze how much ice is left, but even these airplanes were grounded by the clouds of ash.

2) The most likely scenario is a repeat of the 1821 eruption by the same volcano. That eruption sputtered off and on for 13 months. If this occurs again, European aviation may have to play cat and mouse for several weeks to months. Planes will only fly when the jet stream is blowing a certain direction or when the volcano is relatively quiet. Under this scenario, pilots will be in constant fear of encountering ash, which can shut down a plane's engines and sand blast its windshields to such an extent that it is impossible to see through them. There have been about 90 airplane encounters with volcanic ash since 1980, and in one instance all four of the plane's engines were shut down, almost causing a tragedy.

3) The worse case scenario, which is unlikely, involves this eruption triggering another, larger eruption. There are 35 active volcanoes in Iceland, and one eruption has been known to set off another. The worse case happened in 1783, with an eruption lasting eight months. That eruption killed off much of the livestock and agriculture in Iceland, which in turn caused the death of about 25% of the island's population.
