geological units are shown on the map in Figure 1. The Western Volcanic Zone (WVZ)
encompasses the part of the rift which enters land at the western tip of Reykjanes Peninsula
(RP), runs east along the peninsula to the Hengill region, where it turns northward. East off the
Hengill region the rifting shifts approximately 90/media/vedurstofan/utgafa/skyrslur/2009/VI_2009_012.pdf

Earthquake pulses on the caldera rim of 30-90 minutes duration, like the one observed last night, have been characteristic for the seismic activity linked to the caldera subsidence since the beginning of the sequence last summer.
Such pulses were observed several times per day during the first months
