Mathematical Modeling of Strong Ground Velocity Pulses using Spectral Decomposition and Forward Directivity Effects
Introduction The nature of near-field earthquake records is very complicated and uncertain. Due to this complexity, the prediction of the real structural responses has become very difficult. Based on the analysis of the physical characteristics of near-field records, it is possible to use the simplified mathematical models. Near-field ground motions which are often associated with a progressiv...
متن کاملExtraction of Building Damages in the 2007 Niigata-ken Chuetsu-oki Earthquake Using Digital Aerial Images
Remote sensing technology is effective to grasp the damage distributions from various natural disasters, such as earthquakes, tsunamis and volcanic eruptions. After the 2007 Niigata-ken Chuetsu-oki, Japan earthquake, aerial images were taken in the stricken area by several air survey companies in Japan. Airborne remote sensing is more suitable to collect detailed damage distribution because it ...
متن کاملSeismological asperities from the point of view of dynamic rupture modeling: the 2007 Mw6.6 Chuetsu-Oki, Japan, earthquake
We study the ground motion simulations based on three finite-source models for the 2007 Mw6.6 Niigata Chuetsu-oki, Japan, earthquake in order to discuss the performance of the input ground motion estimations for the near-field seismic hazard analysis. The three models include a kinematic source inverted from the regional accelerations, a dynamic source on a planar fault with three asperities in...
متن کاملOn the ionospheric perturbation associated with the 2007 Niigata Chuetsu-oki earthquake, as seen from subionospheric VLF/LF network observations
In order to investigate any precursory effect of ionospheric perturbations associated with the large 2007 Niigata Chuetsu-oki earthquake (16 July 2007) (magnitude, 6.8), we have made full use of our VLF/LF network observation in Japan by examing the four propagation paths; JJI transmitter (Kyusyu, Ebino)-MSR (Moshiri, Hokkaido), JJY transmitter (Fukushima)-MSR, JJY-KOC (Kochi) and JJICBA (Tatey...
متن کاملsource parameters of the 26 april 2007 bam earthquake obtained by the near field accelerograms data
on 26 december 2003 at 05:26lt (01:26gmt), a catastrophic earthquake mw 6.6, seismic moment (6 – 9 ×10 nm) struck the city of bam in the kerman province of southeast iran. the intense shaking in the city caused the complete collapse of nearly every building in the central parts of the city including many of the newer buildings, killing about 40000 people officially. the city lies to the east of...
