Boom goes the volcano

Eyjafjallajokull is creating a big disruption in flights in and out of Europe, but volcanologists say we ain't seen nothing yet.

Historically, each time Eyjafjallajokull has erupted in the past 2,000 years - in 920, in 1612 and between 1821 and 1823 - another volcano nearby - Katla - has exploded within six months. Here's the thing - Katla eruptions are typically 10 times bigger than Eyjafjallajokull.

In other words, Europe better have a contingency plan for flights if this mother goes boom.
