Induced seismicity and hydraulic fracturing for the recovery of hydrocarbons
Abstract We compile published examples of induced earthquakes that have occurred since 1929 that have magnitudes equal to or greater than 1.0. Of the 198 possible examples, magnitudes range up toExpand

Seismic tomography shows that upwelling beneath Iceland is confined to the upper mantle
SUMMARY We report the results of the highest-resolution teleseismic tomography study yet performed of the upper mantle beneath Iceland. The experiment used data gathered by the Iceland HotspotExpand

Post-rifting stress relaxation at the divergent plate boundary in Northeast Iceland
INTERACTION of the elastic lithosphere with the underlying anelastic asthenosphere causes strain to propagate along the Earth's surface in a diffusion-like manner following tectonism at plateExpand

Plate dynamics near divergent boundaries: Geophysical implications of postrifting crustal deformation in NE Iceland
The bulk of a tectonic plate is thought to move continously at a rate consistent with the geologic average. On the other hand, movements are highly episodic at plate boundaries. We study the plateExpand

A cool model for the Iceland hotspot
Several primary features of the Iceland region require a posteriori adaptions of the classical plume hypothesis to explain them, which erodes confidence in this model. These include the lack of aExpand

Icelandic-type crust
SUMMARY Numerous seismic studies, in particular using receiver functions and explosion seismology, have provided a detailed picture of the structure and thickness of the crust beneath the IcelandExpand

Plates vs Plumes: A Geological Controversy
explore melting anomalies and provides useful information about interior of Earth but, sometimes, interpretations based on this are not acceptable to all. Foulger’s emphasis is that seismology aloneExpand

Postrifting anelastic deformation around the spreading plate boundary, north Iceland: 1. Modeling of the 1987–1992 deformation field using a viscoelastic Earth structure
A third Global Positioning System (GPS) survey of a regional network surrounding the Krafla volcanic system, north Iceland, was conducted in 1992 following a major crustal spreading episode whichExpand

Marine and Petroleum Geology
We compile published examples of induced earthquakes that have occurred since 1929 that have magnitudes equal to or greater than 1.0. Of the 198 possible examples, magnitudes range up to 7.9. TheExpand
