Iceland - Geysir and Strokkur

Geysir is the oldest known geyser. Eruptions at Geysir (up to 60 metres) are spectacular but infrequent. In the past, eruptions have stopped for years at a time and authorized government geologists have been known to force an eruption on the Icelandic National Day.



Strokkur is only a few metres away from Geysir but erupts (up to 20 metres) very reliably every 5-10 minutes.
