Depth-varying rupture properties of subduction zone megathrust faults
[1] Subduction zone plate boundary megathrust faults accommodate relative plate motions with spatially varying sliding behavior. The 2004 Sumatra-Andaman (Mw 9.2), 2010 Chile (Mw 8.8), and 2011 Tohoku (Mw 9.0) great earthquakes had similar depth variations in seismic wave radiation across their wide rupture zones – coherent teleseismic short-period radiation preferentially emanated from the dee...
متن کاملHigh-pressure creep of serpentine, interseismic deformation, and initiation of subduction.
The supposed low viscosity of serpentine may strongly influence subduction-zone dynamics at all time scales, but until now its role could not be quantified because measurements relevant to intermediate-depth settings were lacking. Deformation experiments on the serpentine antigorite at high pressures and temperatures (1 to 4 gigapascals, 200 degrees to 500 degrees C) showed that the viscosity o...
متن کاملSimple Crack Models Explain Deformation Induced by Subduction Zone Megathrust Earthquakes
Following the 2010 Maule and 2011 Tohoku earthquakes, many studies have examined the relation between megathrust earthquakes and subsequent deformation. Here, we apply simple models based on mode II shear cracks, including approximated effects of the free surface to study induced deformation during coseismic and early postseismic stages. We distinguish between buried and surface ruptures repres...
متن کاملParallel Solution of Optimal Shape Design Problem Governed by Helmholtz/Potential Flow Equations
In this paper the implementation of shape optimization techniques based on genetic algorithms for airfoil design is presented. The shape of an airfoil is sought such that a cost function depending on the scattered electromagnetic wave and the pressure distribution on the airfoil is minimized. The combined electromagnet-ics//ow problem is modeled by Helmholtz equation and potential ow. The state...
متن کاملProbabilistic Seismic and Tsunami Hazard Analysis Conditioned on a Megathrust Rupture of the Cascadia Subduction Zone
This paper presents a methodology for probabilistic hazard assessment for the multihazard seismic and tsunami phenomena [probabilistic seismic and tsunami hazard analysis (PSTHA)]. For this work, a full-rupture event along the Cascadia subduction zone is considered and the methodology is applied to a study area of Seaside, Oregon, which is located on the US Pacific Northwest coast. In this work...
