Summary

This very small eruption produced fine grained white tephra which is found as a thin discontinuous white tephra layer in soil profiles close to the volcano. Tephra deposits are usually found only within 10 km of the volcano. A jökulhlaup was also produced by this eruption, the flood emerged from the Gígjökull glacier which flows to the north of the volcano. The tephra produced by this eruption is highly silicic (68 to 70% SiO2).
