Thordarhyrna (Icelandic: Þórðarhyrna [ˈθourðarˌhɪ(r)tna] ) is one of seven ⓘ[1] subglacial volcanoes beneath the Vatnajokull glacier in Iceland.
Eruptions
It last erupted in 1910 and prior to that in 1903.[2][3]
An eruption in 3550 BC ± 500 years poured out 150,000,000 cubic meters of lava in the area of Bergvatnsárhraun, to the south of Thordarhyrna.[4]
Geology
There is a mechanical interaction between Thordarhyrna and Grimsvötn, despite these volcanoes being relatively far apart,[6] so the eruption in 1902 - 1904 was combined with an eruption from Grimsvötn and had a Volcanic Explosivity Index (VEI) of 4.[7]
A fault runs (N.35°W) from Thordarhyrna towards Hamarinn, and separates two different tectonic regions.[8]
