Eyjafjallajökull: A.K.A The Icelandic Volcano that Erupted

Living in a place like Iceland can have its setbacks. From ferry schedules based solely on weather forecasts to freak snow storms that hinder road transport, Icelandic people have seen it all. But in 2010 not only the residents of Iceland were affected by the eruption of one of the country’s most active volcanoes.

Located on the Southern tip of the island, Eyjafjallajökull, pronounced Eh-ya-fyat-la-yuh-cuttle, released a violent cloud of volcanic ash that hovered South East along the jet stream bringing air traffic to a halt for weeks; the greatest disturbance in air traffic since WW II. Nearly 500 local farmers and their families were evacuated from the site, and thousands of travels throughout Europe were left stranded.

Ever wonder how a volcano erupts and why?

A volcanic eruption is the change in volume and density of molten rock. Deep below the funnel of a volcano is a series of channels and layers of sediment. Depending on the rock and its proximity to higher temperatures, it will melt into magma. Magma, being less dense than the rock surrounding it, floats towards the surface and is encapsulated into little magma chambers. During this rise to the surface, components such as water, sulfur dioxide, and carbon dioxide expand into steam and when they are pressurized in these chambers, causing an eruption.

A new eruption can be caused by the buoyancy of the magma which deciphers how quickly the magma rises and pressure levels of the gases inside the magma.

Eyjafjallajökull was just an inside glance at how powerful our Earth really is. Because when it comes down to man vs nature, we all know who the undefeated champ really is.
