Dynamic changes of elastic moduli in source volumes are predicted to produce "damagerelated-radiation" associated with products of the changes of elastic moduli and total elastic strain components in the source volume [Ben-Zion and Ampuero, 2009]. Decreasing elastic moduli (as produced by brittle deformation of low-porosity rocks and explosions) increase the radiation to the bulk, while increas...
Prediction of Seismic Damage Using Scalar Intensity Measures Based On Integration of Spectral Values
A key issue in seismic risk analysis within the context of Performance-Based Earthquake Engineering is the evaluation of the expected seismic damage of structures under a specific earthquake ground motion. The assessment of the seismic performance strongly depends on the choice of the seismic Intensity Measure (IM), which quantifies the characteristics of a ground motion that are important to t...
tehran as the biggest metropolitan of iran is located in the areas that are at high-risk of earthquake. what increases tehran's vulnerability toward earthquake is the urban physical expansion in vaious dimensions. since the analysis of the mentioned expansion is a solution to many urban problems, the effects of tehran expansion in increasing vulnerability to earthquake has been surveyed in...
For a quick and stable estimation of earthquake damaged buildings worldwide, using Phased Array type L-band Synthetic Aperture Radar (PALSAR) loaded on the Advanced Land Observing Satellite (ALOS) satellite, a model combining the usage of satellite synthetic aperture radar (SAR) imagery and Japan Meteorological Agency (JMA)-scale seismic intensity is proposed. In order to expand the existing C-...
One of the most important natural hazards that threatens Caracas, the capital city of Venezuela, is the seismic hazard, due to its location in the plate boundary zone between the South America and the Caribbean plates. There is historic evidence for several destructive earthquakes in Caracas since 1641, being the most recent one the 1967 Caracas earthquake. This magnitude 6.5 earthquake which o...
Post-traumatic stress, depression and anxiety symptoms are common outcomes following earthquakes, and may persist for months and years. This study systematically examined the impact of neighbourhood damage exposure and average household income on psychological distress and functioning in 600 residents of Christchurch, New Zealand, 4-6 months after the fatal February, 2011 earthquake. Participan...
Bright curvilinear features in Synthetic Aperture Radar (SAR) images arising from the geometry of urban structures have been successfully used for estimating urban earthquake damage, using single preand post-event high resolution amplitude SAR images. In this paper, further automation of the process of selecting candidate curvilinear features for change detection is proposed, based on a model s...
When rainfall and earthquake occur simultaneously, large-scale landslides can cause direct damage to lives structures. To reduce such landslide damage, earthquake-induced susceptibility has be evaluated. Therefore, in this study, was evaluated by considering only rainfall, earthquake, both the Atsuma region of Japan, where a triggered combination earthquake. Through quantitative index analysis,...
in an earthquake country like iran it is of paramount importance that the structural form be sound. the designer must be able to predict satisfactorily the behavior of the structure in the event of a strong ground motion. in order to be able to make a wise choice, he also should know enough about the consequences of the earthquake damage to the structure and economic factors involved. this pipe...
