Eyjafjallajokull

Eyja-what? Eyjafjallajokull is a volcano in Iceland that has been recently making waves - not with its hard-to-pronounce name, mind you - but with its recent eruption that spewed enough ash to paralyze much of northern Europe's airspace. An earlier eruption on March 20 was just a minor belch - a fissure vent, to be exact - but it was enough to shut down runways in the country and cost Swiss pilot Riccardo Mortara a few hours' delay in his fastest round-the-world flight record (he still won the record, by the way).

The latest eruption, occurring on April 14, caused floods from melting glaciers that required the evacuation of some 800 residents. Moreover, it spewed volcanic ash at a height of up to 11 km above the Earth's surface that  spread to most of northern Europe, grounding flights for several days. Here's an image showing the extent of ash cloud cover from Eyjafjallajokull's April 14 eruption - see how it was able to cover the UK, which was more than 1,000 km away.

Volcanologists from the Norwegian University of Science and Technology (NTNU) that the currrent Eyjafjallajokull eruption can last for as long as a month. Now this has caused both airlines and air travelers in Europe to be both worried and agitated, with grounded flights costing airlines up to $200M a day.

An interesting factoid to note is that Eyjafjallajokull is actually a glacier that covers a volcano of the same name. The Eyjafjallajokull glacier has an area of  about 100 square kilometers, and the volcano sits just below the icecap of the glacier. Eyjafjallajokull volcano has an elevation of just about 5,500 feet and a crater that is about 4 kilometers wide. Here's how both Eyjafjallajokulls look like in more tranquil times:

And by the way, here's how you properly pronounce Eyjafjallajokull. Personally, it sounds like "ey-va-logue" to me...
