Strokkur Geyser – Iceland

A geyser is the result of high-temperature steam rising up from cooling magma beneath, which causes an eruption of water.

Eruptions usually occur with intervals of between 5-10 minutes and involve a single burst reaching a height of up to 30 meters, although occasionally up to 5 bursts in relatively quick succession are observed. Prior to eruptions, the pool is full and gently pulsates up and down. The eruption commences when a pulse of steam rising from below pushes the water in the pool upwards forming a large dome (or bubble) of water through which the steam bursts and expels much of the water in the pool skywards.
