In current research quantifying loss potentials for German city regions basic tools for GIS-based seismic risk assessment technologies have been developed and applied to the building stock and regional particularities of German earthquake regions. Different study areas with comparable levels of seismic hazards were investigated, but they had varying numbers of inhabitants and degrees of urbaniz...

The Iranian plateau has been known as one of the most seismically active regions of the world, and it frequently suffers destructive and catastrophic earthquakes that cause heavy loss of human life and widespread damage. Earthquakes are regularly felt on all sides of the region. Prediction of the occurrence location of the future earthquakes along with determining the probability percentage can...

The recent wave of seismic shocks in Central Italy (2016) had once more disastrous consequences for the local monuments, which consisted of old masonry churches and towers. The permanent, seismic-induced damage to cultural heritage has become a serious issue that can no longer be downsized, and questions have been raised about how to satisfactorily assess the vulnerability of such heritage in a...

The determination of structural and nonstructural damage under earthquake excitations is usually considered as a key factor in performance-based seismic design (PBSD) methods is In this regard, various damage indices have been developed in recent years to quantitatively estimate structural damage. The aim of this study is to develop a simple method to evaluate performance levels of zipper-brace...

A rockburst is a violent failure of a mine opening and is usually associated with deep mining operations. The objective of this research is to detect and reduce rockburst hazards by studying seismic energy release, geostructural data including mine opening closure rates, and in situ stress measurements. Little progress has been made in determining mechanisms of rockbursts, but improved methods ...

Researchers at the National Institute for Occupational Safety and Health (NIOSH), Spokane Mining Research Division (SMRD) have developed a modeling framework, using commercially available software, for investigating the fracture and ejection of rock into underground mine openings caused by seismic loading and the restraint of this failed rock by the ground support system. The modeling framework...
