Volcanic tremor: Nonlinear excitation by fluid flow
A nonlinear process analogous to the excitation mechanism of musical wind instruments and human vocal cords can explain many characteristics of volcanic tremor, including (1) periodic and “chaotic”Expand

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

Imaging the mantle beneath Iceland using integrated seismological techniques
[1] Using a combination of body wave and surface wave data sets to reveal the mantle plume and plume head, this study presents a tomographic image of the mantle structure beneath Iceland to 400 kmExpand

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

NON-DOUBLE-COUPLE EARTHQUAKES. 1. THEORY
Historically, most quantitative seismological analyses have been based on the assumption that earth- quakes are caused by shear faulting, for which the equiv- alent force system in an isotropicExpand

Plume‐driven plumbing and crustal formation in Iceland
[1] Through combination of surface wave and body wave constraints we derive a three-dimensional (3-D) crustal S velocity model and Moho map for Iceland. It reveals a vast plumbing system feedingExpand

Non-double-couple microearthquakes at Long Valley caldera, California, provide evidence for hydraulic fracturing
Abstract Most of 26 small (0.4≲ M ≲3.1) microearthquakes at Long Valley caldera in mid-1997, analyzed using data from a dense temporary network of 69 digital three-component seismometers, haveExpand
