TL;DR: Lateral dyke growth with segment barrier breaking by pressure build-up in the dyke distal end explains how focused upwelling of magma under central volcanoes is effectively redistributed over long distances to create new upper crust at divergent plate boundaries.
ReportDOI
Seismological evidence for Lateral magma intrusion during the July 1978 deflation of the Krafla volcano in NE-Iceland
TL;DR: In this paper, a dyke tip propagated with the velocity of 0.4-0.5 m/sec during the first 9 hours, but the velocity decreased as the length of the dyke increased.
Journal ArticleDOI

TL;DR: In this article, geodetic and seismic data from rare sections of ridges that are exposed on land in Iceland and the Afar region in east Africa demonstrate that rifting episodes at these sites operate with remarkably similar mechanisms.
Journal ArticleDOI
Tectonic stress and magma chamber size as controls on dike propagation : Constraints from the 1975-1984 Krafla rifting episode
TL;DR: In this paper, the authors developed a quantitative model for the lateral propagation of basaltic dikes away from a magma chamber and showed that dikes propagate as long as there is sufficient driving pressure, defined as the difference between magma pressure and tectonic stress at the dike tip.
Journal ArticleDOI
Seismic activity associated with the September 1977 deflation of the Krafla central volcano in northeastern Iceland
TL;DR: The September 1977 deflation event in the Krafla caldera was one of a series of such events that has been in progress since December 1975 as discussed by the authors, and the operation of portable seismographs in the active region and favorable location of the main seismic activity with respect to the permanent seismograph network in NE-Iceland allow a more detailed study of this deflation event than most of the other events.
