The volume of tephra is calculated as freshly fallen. This eruption was silicic, although there are no known deposits outside of Iceland. Most of the tephra was produced during the first 12 hours of the eruption. The tephra was carried to the north-east of the volcano and reached the coast, 330 km, in 5.5 hours. The tephra layer was the smallest known in historical times.
