connects the NVZ to the
offshore Kolbeinsey ridge (KR). The block bounded by the WVZ, EVZ and SISZ is
sometimes called the Hreppar micro-plate (HM). Seismicity is mainly confined to the two
transform zones, the TFZ and the SISZ. This thesis focuses on seismicity in the SISZ, RP
and WVZ.

The hydrological simulations were performed with the Wa-
tershed Simulation and Forecasting System (WSFS) developed
and operated in the Finnish Environment Institute (Vehviläinen
et al., 2005). The WSFS is used in Finland for operational hydrolog-
ical forecasting and flood warnings (www.environment.fi/water-
forecast/), regulation planning and research purposes

is underlain by a dense intrusive complex (probably gabbro), about 12 km in diameter.
Below the centre of the caldera, material with lower density occurs, possibly a caldera fill, a subsided block or
both. Existence of magma chamber is uncertain. If a shallow level magma chamber exists below the
Bárðarbunga volcano a likely location is at the base of the lower density region. Earthquakes occur

than can be expected to originate from the cauldrons, three to four times the wa-
ter equivalent of the accumulation of snow over the watershed of the cauldrons. It has
been estimated that flow from the cauldrons, in addition to the jökulhlaups, could be
2–5 m3 s 1 at maximum (Vatnaskil, 2005). It is possible that part of the sulfate-rich
groundwater from the glacier comes from the cauldrons
