Task 1: Make a detailed study of the faults in the TFZ and the SISZ

Start: July 1996 (month 5)
End: February 1998 (month 24)
Responsible partner: NVI
Cooperative partners: IMOR.DG, UUPP.DGEO

Field inspection of the faults in the SISZ was made in the summer of 1996. Detailed mapping of individual seismogenic faults in the Holocene lavas of the SISZ has already resulted in detailed maps of the Leirubakki-Svínhagi fault and many other faults were studied. This work, which now includes considerations of fluid pressure effects and the relation of seismogenic faults to geothermal systems, is made in collaboration with Helgi Torfason, Icelandic Energy Authority (OS).

A map of the TFZ has been been made in collaboration with Thierry Villemin (see Task 5), who, with his students, is now primarily responsible for this map.
