Geysir is one of Iceland’s top tourist attractions and is the original hot water spout after which all other geysers in the world are named. Geysir used to shoot water 80 meters into the air, but has been clogged since the 1950s when tourists threw rocks into it and now only erupts infrequently. Nearby is Strokkur, a very reliable geyser that gushes 10 to 30 meters of water into the air every five to 10 minutes without fail.

This is just some steam venting, which one actually saw everywhere in Iceland.
