in planning and maintenance; however, as it is characterised by a relatively more
centralised (top-down) type of management.

(purple triangles).
High-precision earthquake locations, with optimum achievable location accuracy on the order
of tens of meters are currently obtained through relative relocation (double difference) of
manually located earthquakes (Slunga et al., 1995; Hjaltadóttir and Vogfjörd, 2005). The
objective is to obtain

faulting. In June 2000, two large earthquakes of magnitudes ML6.4 and ML6.5 struck in the
SISZ, three and a half days and approximately 17 km apart. Seismicity greatly increased in
all Southwest Iceland and during 2000, roughly nineteen thousand microearthquakes were
recorded there. The aim of this research is to relocate the earthquakes using a double-
