an important part of the runoff from many areas. In total, approximately
20% of runoff in Iceland originates from groundwater (Hjartarson, 1994a).
In the above mentioned previous simulation of runoff map for Iceland for the period 1961–
1990, groundwater was omitted. Effects of groundwater flowing across watershed
boundaries were simulated by scaling the precipitation for each watershed. On watersheds

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 maximum discharge of jökulhlaup water at the glacier
terminus is estimated as 97 m3 s 1. This jökulhlaup was a fast-rising jökulhlaup as
other jökulhlaups in Skaftá and cannot be described by the traditional Nye-theory of
jökulhlaups. The total volume of flood water was estimated as 53 Gl. The average
propagation speed of the subglacial jökulhlaup flood front was found to be in the range
0.2–0.4 m s 1

methodology is widely utilized by many automatic earthquake detectors, but instead of having
window lengths on the order of minutes, like the ALERT module, they have window durations
on the order of seconds. A longer STA window duration will make the module less sensitive to
small signals (Trnkoczy, 1999). Additionally, the total duration of the STA and LTA windows
may not exceed 24 hours
