Three - Dimensional Compressional Attenuation Model ( QP ) for the Salton Trough , Southern California by Guoqing

I present a frequency-independent 3D seismic attenuation model (indicated by Q−1 P ) for the crust of the Salton trough and the adjacent regions in southeastern southern California. The simul2000 tomographic algorithm was used to invert the frequency-independent attenuation operator t values measured from amplitude spectra of 23,378 P-wave arrivals of 1203 events through a recently developed 3D...

Spatial and temporal seismic velocity changes on Kyushu Island during the 2016 Kumamoto earthquake

Monitoring of earthquake faults and volcanoes contributes to our understanding of their dynamic mechanisms and to our ability to predict future earthquakes and volcanic activity. We report here on spatial and temporal variations of seismic velocity around the seismogenic fault of the 2016 Kumamoto earthquake [moment magnitude (Mw) 7.0] based on ambient seismic noise. Seismic velocity near the r...

Evaluating Seismic Effects on a Water Supply Network and Quantifying Post-Earthquake Recovery

This paper summarises the impact of major earthquakes, 2010–2011, on Christchurch’s water supply network and what recovery measures have been applied, what worked well, what did not and why. A number of issues related to the open nature of the Christchurch water supply network were identified during earthquakes. It was difficult to manage large water supply pressure zones during the post-earthq...

Variability of earthquake nucleation in continuum models of rate-and-state faults and implications for aftershock rates

[1] Using two continuum models of rate-and-state faults, one with a weaker patch and the other with rheological transition from steady state velocity-weakening to velocity-strengthening friction, we simulate several scenarios of spontaneous earthquake nucleation plausible for natural faults, investigate their response to static shear stress steps, and infer the corresponding aftershock rates. O...

Wave - equation - based travel - time seismic tomography – Part 2 : Application to the 1992 Landers earthquake ( M w 7 . 3 ) area

High-resolution 3-D P and S wave crustal velocity and Poisson’s ratio models of the 1992 Landers earthquake (Mw 7.3) area are determined iteratively by a wave-equationbased travel-time seismic tomography (WETST) technique. The details of data selection, synthetic arrival-time determination, and trade-off analysis of damping and smoothing parameters are presented to show the performance of this ...
