This research provides an in-depth analysis of economic resilience to earthquakes. It fi ne-tunes the defi nition to distinguish inherent and adaptive considerations, and it distinguishes the various levels at which resilience is operative. It explicitly links resilience to the behavior of individuals, markets, and the regional macroeconomy, including disequilibrium aspects of each. Finally, it...

Postseismic slip observed after large (M> 6) earthquakes typically has an equivalent moment of a few tens of percent of the coseismic moment. Some observations of the recurrence intervals of repeating earthquakes suggest that postseismic slip following small (M ≲ 4) earthquakes could be much larger—up to 10 or 100 times the coseismic moment. We use borehole strain data from U.S. Geological Surv...

Coda waves arise from scattering to form the later arriving components of a seismogram. Coda-wave interferometry (CWI) is an emerging tool for constraining earthquake source properties from the interference pattern of coda waves between nearby events. A new earthquake location algorithm is derived which relies on coda-wave-based probabilistic estimates of earthquake separation. The algorithm ca...

earthquake ground-motions show significant variability in both spectral and temporal characteristics. procedures to generalize and predict strong ground motions may be generally divided into three main disciplines: numerical techniques based on a kinematic source description, empirical attenuation models, and semi-empirical stochastic models. numerous studies have shown that, in the near-fault ...

Source parameters of 15 large (mb -> 6) earthquakes which occurred near Taiwan during the last 25 years are determined by synthetic seismogram analysis of teleseismic P and S waveforms. Source depths range from 13 to 88 km. Three earthquakes of intermediate depth are located within the southernmost limit of the Ryukyu arc and show thrust-type mechanisms with T axes subparallel to a northward di...

Earthquakes are one of the most destructive natural hazards on our planet Earth. Hugh earthquakes striking offshore may cause devastating tsunamis, as evidenced by the 11 March 2011 Japan (moment magnitude Mw 9.0) and the 26 December 2004 Sumatra (Mw 9.1) earthquakes. Earthquake prediction (in terms of the precise time, place, and magnitude of a coming earthquake) is arguably unfeasible in the ...

[1] We have developed a double-difference algorithm to relocate earthquakes recorded at global seismic networks, using differential arrival times for first and later arriving regional and global phases to invert for the vectors connecting the hypocenters. Differential times are formed from global seismic bulletins and are accurately measured on similar seismograms by time domain waveform cross ...

Abstract A tsunami earthquake is an event that generates abnormally high waves considering the amplitude of seismic waves. These relative to wave are related longer rupture duration such earthquakes compared with typical events. Rapid magnitude estimation essential for timely issuance effective warnings earthquakes. For local events, estimated from observed displacement amplitudes waves, which ...

[1] Some of the largest and most anomalous volcanic earthquakes have non-double-couple focal mechanisms. Here, we investigate the link between volcanic unrest and the occurrence of non-double-couple earthquakes with dominant vertical tension or pressure axes, known as vertical compensated-linear-vector-dipole (vertical-CLVD) earthquakes. We determine focal mechanisms for 313 target earthquakes ...
