Interesting that this happened in the same year it first appeared.
The 1996 eruption of Gjálp in Iceland was a 13-day subglacial event (Sept 30–Oct 13) beneath the
Vatnajökull ice cap. It triggered massive subglacial melting, producing a catastrophic jökulhlaup (glacial flood) on November 4–7 that destroyed bridges and flooded Skeiðarársandur. The eruption formed a 6–7 km fissure between Bárðarbunga and Grímsvötn volcanoes, melting ~3 km³ of ice and creating a 450m-high hyaloclastite ridge.
