See dip slip.. A shallow-dipping reverse fault which terminates before it reaches the surface. ○   Lettris This earthquake lacked any surface rupture, but had an uplift signature associated with the anticline, arguing for a direct relationship between blind-thrust fault- Search English thesaurus is mainly derived from The Integral Dictionary (TID). Because of the lack of surface evidence, blind thrust faults are difficult to detect until they rupture. Give contextual explanation and translation from your sites !

The Wilmington blind thrust fault may represent one of the largest deterministic seismic hazards in the United States, in that it extends for more than 30 km along strike beneath the densely populated Los Angeles metropolitan area and the Ports of Los Angeles and Long Beach. After a long period of erosion the visible landscape may be flattened, with material eroded from the hills filling up the valleys and hiding the underlying hill-and-valley geology. Most English definitions are provided by WordNet . Motion on these faults produces north–south shortening by lateral crustal extrusion. thrust fault. ... California, was caused by a previously undiscovered blind thrust fault. A blind thrust earthquake is an earthquake along a thrust fault that does not show signs on the Earth's surface, hence the designation "blind".

A blind trust is a trust established by the owner (or trustor) giving another party (the trustee) full control of the trust. Resolving how blind thrusts propagate upward and laterally thus depends on our ability to restore fault-related fold, typically based on analysis of synorogenic sediments. The Los Angeles Basin and San Fernando Valley contain soft sedimentary rocks that tend to fold around the tips of thrust faults, so that there is no apparent deformation on the surface.

Los Angeles, California, USA has had many earthquakes, and the area is studied intensively. Blind thrust fault. A thrust fault that does not rupture all the way up to the surface so there is no evidence of it on the ground. The study found that "the tectonic squeezing across Los Angeles will likely produce earthquakes on either the blind Elysian Park or Puente Hills thrust fault systems". Thrust faults are reverse faults that dip less than 45°. ○   Boggle. (geology) A type of thrust fault, which does not appear on the surface, being completely hidden underneath ductile surface rock layers. Because of the lack of surface evidence, blind thrust faults are difficult to detect until they rupture. We document several blind‐thrust faults under the Los Angeles basin that, if active and seismogenic, are capable of generating large earthquakes (M = 6.3 to 7.3).Pliocene to Quaternary growth folds imaged in seismic reflection profiles record the existence, size, and slip rates of these blind faults. [1] Such faults, being invisible at the surface, have not been mapped by standard surface geological mapping. The seismological background of the Northridge earthquake on a blind thrust fault is presented. Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012. segmented blind-thrust system that is manifest at the surface as a series of en echelon anticlines (Figure 1) [Stein and Ekstro¨m, 1992]. Definition from Wiktionary, the free dictionary. A type of thrust fault, which does not appear on the surface, being completely hidden underneath ductile surface rock layers, The numerical value of blind thrust fault in Chaldean Numerology is: 7, The numerical value of blind thrust fault in Pythagorean Numerology is: 9. Definitions.net. Sometimes they are discovered as a by-product of oil exploration seismology; in other cases their existence is not suspected. In addition to surface faults, a number of blind-thrust faults have been found under the basin and metropolitan area [3][4]. Although usually of magnitude 6 to 7 compared to the largest magnitude 9 earthquakes of recent times, it is especially destructive because the seismic waves are highly directed, and the soft basin soil of the valley can amplify the ground motions tenfold or more. Letters must be adjacent and longer words score better. As shown in the diagram, a weak plate under compression generally forms thrusting sheets, or overlapping sliding sections.  | Last modifications, Copyright © 2012 sensagent Corporation: Online Encyclopedia, Thesaurus, Dictionary definitions and more. If the region is under active compression these faults are constantly rupturing, but any given valley might only experience a large earthquake every few hundred years. Giga-fren. Definition of Thrust fault 1. Thin skinned deformation. Sometimes they are discovered as a by-product of oil exploration seismology; in other cases their existence is not suspected.

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. It is buried under the uppermost layers of rock in the crust. "Foreland fold and thrust belts" typically involve shelf rocks or a former continental margin (or miogeocline). Because the old data showed the undeformed layers, people thought that the fault must be inactive. A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. English [] Noun [].
