Eyjafjallajökull, Iceland

December 2009: seismic activity was detected in the volcano area, with thousands of small earthquakes (mostly magnitude 1–2 on the Richter magnitude scale, with only a couple greater than 3 magnitude) 7–10 kilometres (4.3–6.2 mi) beneath the volcano.

26 February 2010: unusual seismic activity along with rapid expansion of the Earth's crust was registered by the Meteorological Institute of Iceland.This gave geophysicists evidence that magma was pouring from underneath the crust into the magma chamber of the Eyjafjallajökull volcano and that pressure stemming from the process caused the huge crustal displacement at Þorvaldseyri farm.

3-5 March 2010: The seismic activity continued to increase and close to 3,000 earthquakes were measured at the epicentre of the volcano.

20 March 2010: The eruption is thought to have begun, about 8 kilometres (5.0 mi) east of the top crater of the volcano in a popular hiking region called Fimmvörðuháls. This first eruption, in the form of a fissure vent, did not occur under the glacier and was smaller in scale than had been thought by some geologists.

14 April 2010: Eyjafjallajökull resumed erupting after a brief pause, this time from the top crater in the centre of the glacier, causing meltwater floods (also known as jökulhlaup) to rush down the nearby rivers, and requiring 800 people to be evacuated. This eruption was explosive in nature and is estimated to be ten to twenty times larger than the previous one in Fimmvörðuháls. This second eruption threw volcanic ash several kilometres up in the atmosphere which led to air travel disruption in northwest Europe for six days from 15 April 2010, including the closure of airspace over most of Europe. The eruptions also created rare electrical storms.

I have been receiving emails from friends who knew I might be interested in the content. Here are some of the photos taken by photographers as credited underneath each image. I could only admire them in awe and with one thought: I wish I was there!

The volcano in southern Iceland's Eyjafjallajokull glacier sends ash into the air just prior to sunset ON Friday, April 16, 2010. Thick drifts of volcanic ash blanketed parts of rural Iceland on Friday as a vast, invisible plume of grit drifted over Europe, emptying the skies of planes and sending hundreds of thousands in search of hotel rooms, train tickets or rental cars.
