Arenal Volcano

Costa Rica - Dec, 2008

  • Arenal is the most active volcano in Costa Rica and has been in a state of almost continuous eruption since 1968. It is common for the mountain to be cloaked in thick cloud and spotting the summit during the rainy season is not easy. I was able to get up onto the slopes of Arenal, into the dangerous prohibited area with an international group of volcanologists and geologists who were installing an array of seismometers on the volcano.

    Burying and aligning one of the seismometers. These sensitive instruments measure tremors on the mountain. The rocks here were deposited by an eruption in 2000 that killed 2 people.
