Volcanic systems are swarms of tectonic fractures and basalt volcanoes formed as a result of
plate-pull (as the plates are pulled apart) associated with the mid-ocean ridges and the …

Using detailed microearthquake data, we present a stress tensor inversion scheme with new
methods for selecting the fault planes and allowing for errors in the focal mechanisms. The …

Field and photogeological studies were made of 90 zones of interacting fracture segments
along the rift zone of Iceland. Each zone consists of a pair of extension fractures or a pair of …

The Tjörnes Fracture Zone is a transform fault connecting the rift zone of the Kolbeinsey
Ridge with that of north Iceland. The main transform motion takes place on the Húsavík …

Dykes and sills occupy Mode I (extension), Mode II (shear), or hybrid mode fractures and
most of the time transport and store magma from deep reservoirs to the surface. Subject to …

Unlike most of the Mid‐Atlantic Ridge, the North America/Eurasia plate boundary in Iceland
lies above sea level where magmatic and tectonic processes can be directly investigated in …

The Húsavı́k–Flatey Fault (HFF) is an oblique dextral transform fault, part of the Tjörnes
Fracture Zone (TFZ), that connects the North Volcanic Zone of Iceland and the Kolbeinsey …

The South Iceland Seismic Zone (SISZ) trends E–W between two major volcanic rift zones of
Southern Iceland. It is 20–60 km wide and 70 km long, and characterized by important …

A multiple-sill laccolith nested within a centrally-dipping sheet swarm is a recently
discovered sub-volcanic structure, resembling a “flower” in section-view, which we have …

The largest earthquakes in Iceland are associated with strike-slip faults in the South Iceland
Seismic Zone (SISZ). Major destructive earthquake sequences occur in this zone at an …
