Rupture Process of the 2004 Sumatra-Andaman Earthquake
The 26 December 2004 Sumatra-Andaman earthquake initiated slowly, with small slip and a slow rupture speed for the first 40 to 60 seconds. Then the rupture expanded at a speed of about 2.5 kilometersExpand
The 2011 Magnitude 9.0 Tohoku-Oki Earthquake: Mosaicking the Megathrust from Seconds to Centuries
Detailed geophysical measurements reveal features of the 2011 Tohoku-Oki megathrust earthquake and suggest the need to consider the potential for a future large earthquake just south of this event. Expand
Upper mantle shear structure of North America
Summary. The waveforms and travel times of S and SS phases in the range 10"-60" have been used to derive upper mantle shear velocity structures for two distinct tectonic provinces in North America.Expand
Source Description of the 1999 Hector Mine, California, Earthquake, Part I: Wavelet Domain Inversion Theory and Resolution Analysis
We present a new procedure for the determination of rupture complexity from a joint inversion of static and seismic data. Our fault parameterization involves multiple fault segments, variable localExpand
The 2005, Mw 7.6 Kashmir earthquake: Sub-pixel correlation of ASTER images and seismic waveforms analysis
We analyze the M_w 7.6 Kashmir earthquake of October 8, 2005, using sub-pixel correlation of ASTER images to measure ground deformation, and modeling seismic waveforms. The surface rupture isExpand
Advancement in source estimation techniques using broadband regional seismograms
One important constraint on source retrieval from regional seismograms comes from the amplitude difference between various phases (such as Pnl/surface wave, SV/SH). Because the misfit errors used inExpand
Determination of source parameters at regional distances with three‐component sparse network data
We find remarkable similarities between regional body waves recorded by the TERRAscope network of broadband stations and synthetics constructed from a standard southern California velocity model.Expand
Sharp Sides to the African Superplume
Using a fortuitous set of SKS phases that travel along its eastern side, it is shown that the boundary of the anomaly appears to be sharp, with a width less than 50 kilometers, and is tilted outward from its center. Expand
Slip history and dynamic implications of the 1999 Chi‐Chi, Taiwan, earthquake
We investigate the rupture process of the 1999 Chi-Chi, Taiwan, earthquake using extensive near-source observations, including three-component velocity waveforms at 36 strong motion stations and 119Expand
Superficial simplicity of the 2010 El Mayor-Cucapah earthquake of Baja California in Mexico
The geometry of faults is usually thought to be more complicated at the surface than at depth and to control the initiation, propagation and arrest of seismic ruptures. The fault system that runsExpand
