A group of volcanologists on a field trip observe activity at the Olkeduháls geothermal field of the Hrómundartindur volcanic system. The latest eruption at Hrómundartindur occurred about 11,000 years ago, from a vent about 1 km N of this geothermal field. The eruption produced a small lava flow, which reached about 4-5 km from the vent and covered about 4 km2.
