This paper examines the consistency of seismicity and ground motion models, used for seismic hazard analysis in New Zealand, with the observations in the Canterbury earthquakes. An overview is first given of seismicity and ground motion modelling as inputs ...

Impact between structures of bridge sections can play a major, unexpected role in seismic structural damage. Linear and non-linear models are developed to analyze structural impact and response of two single-degree-of-freedom structures, representing adjacent ...

On 4 September 2010, a surface rupturing earthquake (Mw 7.1) struck the Canterbury Plains region in New Zealand's South Island. The Canterbury Plains is a region of relatively low seismicity, and the structure that ruptured was a previously unmapped fault. ...

We compare site-specific response spectra and hazard maps from the recently-updated national seismic hazard model (2010 NSHM) and predecessor NSHM of 2002. The new model incorporates over 200 new onshore and offshore fault sources, and utilises newly-developed ...

The main reason for the generation of tsunamis is the deformation of the bottom of the ocean caused by an underwater earthquake. Usually, only the vertical bottommotion is taken into account while the horizontal co-seismic displacements are neglected in the ...

<p>We review the long term evolution of seismicity in the eastern Marmara Sea over a decade, before and after the 1999 Mw 7.6 Izmit earthquake. We analyze large scale space-time variations of seismicity in the region and illustrate the impact of the recent ...

Development and initial applications of a sand plasticity model for nonlinear seismic deformation analyses involving liquefaction are described. The model follows the basic framework of the stress-ratio controlled, critical state compatible, bounding surface ...

<p>Any earthquake can trigger more earthquakes. This triggering occurs in both the classical aftershock zone as well as the far field. These populations of triggered earthquakes may or may not be distinct in terms of triggering mechanism. Here we look for ...

<p>Crustal deformation is the study of active geophysical processes that occur within he earth&rsquo;s lithosphere. Geodesy provides facilities to investigate the earth&rsquo;s crust ovements and shares these data with the other disciplines. The various sources ...

The focus of geotechnical design, construction, and maintenance supportwithin the context of WSDOT is to insure that the soil or rock beneaththe ground surface can support the loads and conditions placed on it bytransportation facilities.
