Prestahnukur volcano is a large subglacial shield volcano in SW Iceland. It is located beneath at the SW end of the Langjökull icecap. Prestahnukur has rift zones to the north and SW. Eruptions occurred from the rift zones in the past 10,000 years.

Background:

Hot springs are associated with the rhyolitic Prestahnukur central volcano. The classic Icelandic shield volcano Skjaldbreidur was formed at the southern end of the Prestahnukur volcanic system, between Thorsjökull glacier and Thingvallavatn lake. The broad, low-angle shield volcano produced 17 cu km of basaltic lava flows during the early Holocene.
