rupture zone

The region immediately adjacent to the crater boundary in which the stresses produced by the explosion have exceeded the ultimate strength of the medium. It is characterized by the appearance of numerous radial cracks of various sizes. See also plastic zone.

Or the fault's rupture zone, which in this case was estimated to be about 110 kilometres long, may pass through an area where the sea floor rises or drops off, so that when the fault moves during the quake, it pushes seawater in front of it.
However, there are still two problems worthy of our attention: (1) whether the fault rupture zone can be exposed at the surface along a fault outcrop and (2) what the deformation of the ground is and what causes significant deformation of the ground caused by a rupture of the overlying soil.
The observation of present-day seismic events from various geodynamic environments demonstrates that the outward propagation of the triggering front from the main rupture zone is governed by the transient diffusion of overpressured fluid [111, 112, 123-126].
Bars of the constant WT configuration (indicated by the hatching) show a much lower stress level in the rupture zone, compared to the values found with patient-specific wall thickness.
The MGB team also recommended the declaration of five new GeoPark (geological) sites-Maribojoc-Loon Uplifted Reef Flats, Catigbian Karst Window, Sagbayan Spalling Hills and Sinkholes, Danao Gorge and Dagohoy Hill, and Inabanga Rupture Zone.
The team drilled three holes in the Japan Trench area to study the rupture zone of the 2011 earthquake, a fault in the ocean floor where two of the Earth's major tectonic plates meet, deep beneath the surface of the Pacific Ocean.
While the new report raises concern about the area next to the rupture zone, the issue also extends globally, said Thorne Lay, an earthquake expert and professor at the University of California, Santa Cruz.
One of those segments, just to the east of the rupture zone, is even closer to Port-au-Prince than the January rupture.
A conceptual model of the "source radius" commonly used by seismologists employs an equivalent circular rupture zone to the actually ruptured zone.
