The puzzle of the 1996 Bardarbunga, Iceland, Earthquake: No volumetric component in the source mechanism

A volcanic earthquake with Mw 5:6 occurred beneath the Bárdarbunga caldera in Iceland on 29 September 1996. This earthquake is one of a decade-long sequence of M 5 events at Bárdarbunga with non-double-couple mechanisms in the Global Centroid Moment Ten
