volcanic and seismic events as proof Reducing tectonic risk earthquake proof building be in place prior to events so that emergency services know what to do during a volcanic or earthquake event.

Hengill. Triple junction between the Reykjanes Volcanic Zone, The Western Volcanic Zone, and the South Iceland Seismic Zone. Seismicity of the Hengill volcanic system, normal faulting and seismicity associated with geothermal activity. South Iceland Seismic Zone. Reykjanes Peninsula. The Reykjanes Peninsula is a zone of high seismicity and recent volcanism that forms a transition between the Reykjanes Ridge to the west and the Western Volcanic Zone and the South Iceland Seismic Zone to the east. The plate boundary can be defined as a narrow seismic zone that enters Iceland near the tip of Reykjanes (Fig. 3) and runs along the peninsula. Detailed studies by Klein et al. (1973, 1977) show that the seismic zone is less than 2 km wide in most places. The earthquakes mostly occur at a depth of l-5 km and are not located on any one particular fault. The seismicity seems to be caused by deformation of a brittle crust above a deeper seated. aseismic deformation zone. Small-scale structures and seismic lineations can be resolved within the zone, striking obliquely or even transversely to the main zone. Normal faulting is the most common faulting mechanism. Further to the east in this region strike-slip faulting becomes more prominent. In the Hengill volcano in Southwest Iceland, many events involve a non-double-couple mechanism. The seismicity is interpreted as the result of extensional failure and heat extraction from a cooling magma chamber.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
