Earthquakes and present-day tectonism in Iceland

P Einarsson - Tectonophysics, 1991 - Elsevier
The mid-Atlantic plate boundary in Iceland is expressed by a series of seismic and volcanic
zones. The structure of the plate boundary is strongly influenced by the Iceland hot spot. The …

Tomographic inversion of local earthquake data from the Hengill‐Grensdalur central volcano complex, Iceland

DR Toomey, GR Foulger - Journal of Geophysical Research …, 1989 - Wiley Online Library
We have determined the three‐dimensional P wave velocity structure within the area of the
Hengill‐Grensdalur central volcano complex, southwest Iceland, from the tomographic …

Dike‐induced faulting and graben subsidence in volcanic rift zones

AM Rubin - Journal of Geophysical Research: Solid Earth, 1992 - Wiley Online Library
Field observations and geodetic data indicate that dike intrusion in volcanic rift zones
typically generates normal faulting and graben subsidence at the Earth's surface. Elastic …

Dynamics of crustal rifting in NE Iceland

A Björnsson - Journal of Geophysical Research: Solid Earth, 1985 - Wiley Online Library
Magnetotelluric measurements have revealed a crustal thickness of 8–10 km in the axial rift
zone of NE Iceland and above the proposed hot spot in central east and north Iceland. The …

Integration of knowledge of subglacial topogra-Phy, earthquake activity and jökulhlaups has
contributed to more precise locations ofthe volcanic systems beneath Vatnajökull …

Iceland geochemical anomaly: origin, volcanotectonics, chemical fractionation and isotope evolution of the crust

N Oskarsson, S Steinthorsson… - Journal of Geophysical …, 1985 - Wiley Online Library
Iceland is an oceanic plateau produced by channeled flow from the Iceland hotspot. The
Icelandic rift system moves WNW relative to the hotspot. About magnetic anomaly 7 time the …

A comparison of rift-zone tectonics in Iceland and Hawaii

AM Rubin - Bulletin of Volcanology, 1990 - Springer
Observations of eroded volcanic rift zones indicate that dikes in Iceland are typically several
times thicker than those in Hawaii. Geodetic and seismic observations of active rifts …
