Katla (Southern Iceland): (9 Jun) An article on mbl.is reports that unusually strong earthquake activity at Katla volcano may indicate the system is close to a critical stress threshold. Geophysicist Halldór Geirsson said one possible interpretation is that Katla is “in many ways close to its expansion limits,” meaning that even small changes in magma volume could trigger increased earthquake activity in different parts of the volcano. … [read more] … [show less] Katla, located beneath the Mýrdalsjökull ice cap in southern Iceland, has recently produced unusually intense seismic activity, possibly among the strongest recorded since modern monitoring began. However, Geirsson emphasized that scientists do not all agree on this interpretation. The instrumental record is relatively short, and measuring crustal deformation beneath a glacier is especially difficult.
