By comparing airborne lidar measurements of the glacier surface, that were carried out in September 2008, with a digital terrain model by the mapping company Loftmyndir ehf from 1999, the average lowering of the ice surface

The conference will be held on October 30th 2009 in Reykjavík, Iceland, and is dedicated to the memory of Sigurður Th. Rögnvaldsson, geophysicist, who died on 25th October 1999. He was highly respected in earthquake research in Iceland

mechanisms and the relationship between b-values and source depth
is examined. During the analysis period, three major swarms were recorded. Two of the
swarms, in 1994 and 1999–2000, occurred in the upper crust and were accompanied by
crustal deformation. No uplift was detected during the third swarm, which occurred in
1996 near the crust mantle boundary, between 19 and 25 km depth

The current period of unrest began in July 2011, when a short-lived glacial flood burst from Mýrdalsjökull in connection with increased seismicity. Since then, several hundred micro-earthquakes have taken place within the area of the caldera. The enclosed graph shows how the ongoing activity compares to earlier episodes of seismic unrest at Katla in 1999 and 2002-2004.

extracted for each hydrological year (taken here from Sept 1 to Aug 31), from monthly max-
imum instantaneous flow series. Years with more than two missing months were omitted. As
the AMF of year 1999 at gauging stations vhm102 and vhm233 was strongly suspected to be
caused by a jökullhlaup, the 2nd largest annual flow was selected for this year. One must bear
in mind that uncertainties

(Björnsson, 1976). Generally, jökulhlaups from marginal lakes have decreased due
to thinning of glaciers during the twentieth century because lower ice dams cause the
lakes to burst at a lower water level. This leads to smaller but more frequent jökul-
hlaups.
Other types of floods can also originate in marginal glacier lakes. For example,
