E15 Activity
• Started in 2009 and increased intensity up until March 2010
• Volcanic Events that started in March 2010 are all considered to be part of a single eruption.

• April 14, 2010 E15 entered into the Explosive Phase
• Estimated to be a VEI 4 Eruptions

Flooding• Volcanic heat melting glacier ice which effected the rivers.• The fear of flooding made it so authorities evacuated 800
people from the area around the melting.• The steepness of the volcano made the waters much more
powerful.

Problems with air travel?
• Results of four factors:– First the volcano is located under the Jet stream. – Power of volcano’s explosion. – The second eruption allowed water from the melted
glacial ice to flow back into the erupting
volcano and createstwo more phenomena.
