My second stop on the Golden Circle tour was at the famous Icelandic geysers, the almost dormant Geysir (meaning “to gush” in Icelandic) and the frequently erupting Strokkur (meaning “to churn” in Icelandic). A geyser is a spring that turbulently discharges hot water followed by steam into the air at various intervals. Geysers are usually found in areas with volcanic activity. Geyser activity, like all hot spring activity, is caused by surface water gradually seeping down through the ground until it meets rock heated by magma. The geothermal heated water then rises back toward the surface by convection through porous and fractured rocks. Strokkur is one of Iceland’s most famous geysers erupting about every 8-10 minutes, some 15-20 meters high, occasionally up to 40 meters high!
