S U M M A R Y Slip-rate function and the rupture velocity are two important parameters that are critical in understanding the physics of earthquakes. When conventional objective functions are used, the slip-rate function is not well resolved from seismic data. Here, we propose a new method to obtain the slip-rate function by utilizing the near-field phases recorded near the fault rupture. First...

The 11 March 2011 Mw9.0 Tohoku-Oki earthquake was recorded by an exceptionally large amount of diverse data offering a unique opportunity to investigate the details of this major megathrust rupture. Many studies have taken advantage of the very dense Japanese onland strong motion, broadband, and continuous GPS networks in this sense. But resolution tests and the variability in the proposed solu...

An Efficient Logic Fault Diagnosis Framework Based on Effect-Cause Approach. (December 2007) Lei Wu, B.S., Sichuan University, China; M.S., Sichuan University, China; M.S., McNeese State University Chair of Advisory Committee: Dr. Duncan M. Walker Fault diagnosis plays an important role in improving the circuit design process and the manufacturing yield. With the increasing number of gates in m...

Abstract The 2016 Kumamoto earthquakes caused severe damage centering on the Mashiki residential area. velocity waveforms at station KMMH16 in Mashiki, during M 7.3 mainshock, show large pulses. We found that may be result of strong westward pulse. question raised is how near-fault ground motions with pulse were generated mainshock. focus characterized source model Strong Motion Generation Area...

This study investigates near-field ground motion variability due to dynamic rupture models with heterogeneity in the initial shear stress. Ground velocity seismograms are synthesized by convolving the time histories of slip velocity obtained from spontaneous dynamic rupture models with Green’s functions of the medium calculated with a discrete wavenumber / finite element method. Peak ground vel...

ABSTRACT The structural complexity of active faults and the stress release history along fault system may exert control on locus extent individual earthquake ruptures. Fault bends, in particular, are often invoked as a possible mechanism for terminating However, there few records available to examine how these factors influence along-fault recurrence earthquakes. We present new paleoearthquake ...

The Atlantic coasts of Morocco are exposed to tsunami risk. Although this risk level is low because the rarity tsunamis in region, a future event would be catastrophic for Moroccan society and economy numerous issues at stake. In paper, bathymetric/topographic data parameters three known tsunamigenic faults (Marquês do Pombal Fault, Gorringe Bank Fault Horseshoe Fault) were used simulate potent...
