S U M M A R Y Wepresent and use a phase coherence approach to identify seismic signals that have similar path effects but different source time functions: co-located earthquakes and tremor. Themethod used is a phase coherence-based implementation of empirical matched field processing, modified to suit tremor analysis. It works by comparing the frequency-domain phases of waveforms generated by t...

S U M M A R Y We analyse radar interferometric and GPS observations of the displacement field from the 1995 July 30 Mw = 8.1 Antofagasta, Chile, earthquake and invert for the distribution of slip along the co-seismic fault plane. Using a fixed fault geometry, we compare the use of singular-value decomposition and constrained linear inversion to invert for the slip distribution and find that the...

Earth orientation parameters (EOPs) provide a link between the International Celestial Reference Frame (ICRF) and the International Terrestrial Reference Frame (ITRF). Natural geodynamic processes, such as earthquakes, can cause the motion of stations to become discontinuous and/or non-linear, thereby corrupting the EOP estimates if the sites are assumed to move linearly. The VLBI antenna at th...

Pulverisation of rocks occurs through dynamic processes associated with earthquake ruptures. At the well-known pulverised rock outcrops along San Andreas Fault (SAF), intensity pulverisation was shown to be highly heterogeneous on outcrop (m–10s m) scale, although detailed documentation this heterogeneity is still lacking. Here we derive a standardized classification method for applicable field...

This paper looks at issues associated with estimating risk of seismically initiated failure (uncontrolled release of the reservoir) of dams that are co-located with respect to each other and the location of future earthquakes. These may be dams on the same river or dams regionally co-located on different rivers. Failure of one or more dams could lead to serial dam failures on a single river; or...

JEL Classification J33, L85, M52. This study investigated the effects of salary structure, performance requirements, and type of business on the performance of housing agents. The participants in the study survey consisted of the employees of real estate firms in Kaohsiung, Taiwan. Restricted and unrestricted regression models were used to compare the goodness-of-fit of the regression models. A...

SUMMARY The Gutenberg–Richter (GR) and the Omori–Utsu (OU) law describe earthquakes’ energy release temporal clustering are thus of great importance for seismic hazard assessment. Motivated by experimental results, which indicate stress-dependent parameters, we consider a combined global data set 127 main shock–aftershock sequences perform systematic study relationship between shock-induced str...
