A small phreatic eruption seems to have taken place on August 16, 2013 at the subglacial Kverkfjöll volcano, Iceland. The steam-driven explosion followed a small glacial flood on August 15.

On October 20, 2013 a small earthquake swarm occurred at the volcano with about 20 quakes. The largest was a magnitude 2.6 event at 1.1 km depth.
GVP has no records in their weekly volcano overview database. Last known eruption of this volcano occurred in 1968.
Kverkfjöll is a large subglacial volcano at the NE end of the Vatnajökull icecap. Two elliptical ice-filled calderas, 8 x 5 km in diameter, have been identified. An associated fissure swarm can be traced 60 km to the NE. A half dozen ridges of subglacially erupted pillow lavas are now exposed and extend beyond the glacial icecap to the NE.
Subglacial historical eruptions have been recorded since the mid-17th century. Several other historical eruptions once attributed to Kverkfjöll are now thought to have originated from Bárdarbunga volcano to the west (GVP).
