Lokahryggur
Iceland
64.48 N, 17.80 W
summit elevation 1570 m
subglacial volcano
Subglacial Loki-Fögrufjöll volcanic system is located WNW of Grímsvötn volcano.
Tephra was erupted in 1910. Possible subglacial eruptions were reported during 1986 and 1991.
2011 Eruption
A glacial outburst resulted from a subglacial eruption of Loki-Fögrufjöll Volcano on Tuesday night 12th July 2011. The glacial burst occurred from Köldukvíslarjökull, a part of Vatnajökull in southeast Iceland, in a location which was not previously known to have a geothermal area. The flood flowed down the Svedja river into Hágöngulón lagoon and lake Thórisvatn. A flood has never been recorded at this part of the glacier before, although the volcano possibly had subglacial eruptions in 1986 and 1991 from different locations. The water level of Hágöngulón rose 70 centimeters during the flood.
