Mashhad city, the second most populous metropolis of Iran, with a population of more than three million, lies between two seismically active regions of Binalood and Kopet-Dagh. In recent years, the city has grown around the South Mashhad (SM) fault zone in the south. Given the vital role of the SM fault in influencing the seismic risk of the city, this study is aimed at the evaluation of the fa...

Ocular microtremor (OMT) is a fine high frequency tremor of the eyes caused by extra-ocular muscle activity stimulated by impulses emanating in the brain stem. Several studies have shown that the frequency of this tremor is reduced in patients whose consciousness is reduced by anaesthesia or head injury. Therefore, OMT may possibly be used to determine depth of anaesthesia. Twenty-two unpre-med...

Multiple earthquakes have been felt in high-rise buildings Bangkok despite the epicenters being far away. Seismic wave recordings basin show a low-frequency peak. This study uses horizontal-to-vertical spectral ratio (HVSR) analysis and array of ambient vibration data to find predominant period ground shear velocity profiles at five sites Bangkok. The accuracy accelerometer used for recording w...

Abstract In 2006, the Special Region of Yogyakarta was shaken by a destructive earthquake. The United States Geological Survey (USGS) recorded that earthquake had magnitude 6.3 M w at depth 12.5 km below surface triggered strike slip fault activity. severe damage occurred in Bantul district and Klaten district, where area location were far from epicenter. This proves source distance are not onl...

Abnormalities in the oculomotor control mechanism of patients with idiopathic Parkinson's disease are well recognised. In this study the effect of Parkinson's disease on tonic output from oculomotor nuclei was studied by using oculomicrotremor as an index of such output. Oculomicrotremor readings were taken from 22 parkinsonian patients and 22 normal healthy volunteers using the piezoelectric s...

by growing the population and need for settlement, many cities have been built on soft sediments and seismic areas. it emphasizes the need for a careful and reliable assessment of site effect phenomena. beyond the methods of studying site effects, microtremor recordings has become popular over the last decades as it offers a convenient, practical and low cost tool to be used in urbanized areas....

Abstract The geotechnical industry has widely adopted the refraction microtremor shear-wave velocity measurement technique, which is accepted by building authorities for evaluation of seismic site class around world. Clark County and City Henderson, Nevada, populated their Earthquake Parcel Map with over 10,000 measurements code enforcement, made a 3-year period. 2D analysis now allows engineer...
