A number of tools and advancements have been developed over the course of the last decade for public use in regional seismic disaster planning. This paper addresses some of the considerations and approaches that influence state-of-theart regional seismic loss assessments and risk management, with particular emphasis on approaches applied to areas having potentially high consequence but low prob...

The high accuracies and realistic confidence assessments demanded for seismic monitoring of hydraulic fracturing work require specialist experimental approaches. These include seismic network design based on quantitative modeling, high-quality instrument deployments, and accurate and detailed crustal models. Confidence estimates must take into account uncertainties about crustal structure, whic...

We adopt a spectral-element method (SEM) to perform numerical simulations of the complex wavefield generated by the 6 April 2009 Mw 6.3 L’Aquila earthquake in central Italy. The mainshock is represented by a finite-fault solution obtained by inverting strong-motion and Global Positioning System data, testing both 1D and 3D wavespeed models for central Italy. Surface topography, attenuation, and...

The problem of measuring the solar age by means of helioseismology has been recently revisited by Guenther & Demarque (1997) and by Weiss & Schlattl (1998). Different best values for tseis and different assessment of the uncertainty resulted from these two works. We show that depending on the way seismic data are used, one may obtain tseis ≈ 4.6Gy close to the age of the oldest meteorites, tmet...

Adobe construction represents 5.3% of the total Portuguese building stock according to latest National Housing Census. The distribution these adobe buildings is scattered across country, with higher density in central region and Algarve south, where seismic hazard highest. A large proportion are still use for residential commercial purposes historical significance, contributing cultural heritag...

This paper briefly reviews the development of earthquake resistant design of buildings. The state-of-the-art of seismic design is discussed from the viewpoint of the performance criteria of buildings. These are (a) serviceability from frequent minor-intensity earthquake motions, (b) repairability from an infrequent but major-intensity earthquake motion, and (c) life safety from the maximum poss...
