Seismic hazard zoning in Urmia urban area.
author
Abstract:
Today, the resiliency of the human centers, especially urban centers against the natural hazards such as earthquakes, is one of the main challenges in the targeted management of urban. One of the effective strategies in the control, containment and prevention of risks from earthquakes is zoning of urban areas in terms of vulnerability. In this regard, the purpose of this study was to determine the zoning and seismic active zones in the urban area of Urmia city. The seismic – tectonic situation and recorded seismic data surveyed in the current study. findings showed that there were seismic active zones in the Uremia city area. The seismic effects and geo-tectonic results Verified, so the results marked that local geology condition would be effective in earth motion. This research investigated the local geology features especially fault, geo units and seismic data in zoning of seismic risk. Many methods are proposed by different researchers. In this study the SABTA (1987) method has been used for estimating seismic risk by using most important parameters such as seismic, fault and geology data. The obtained results showed that the P.G.A measure variation was from 0.035 to 0.33 which indicated the existence of seismic activity in the study area.

Fuzzy Inference System Approach in Deterministic Seismic Hazard, Case Study: Qom Area, Iran
Seismic hazard assessment like many other issues in seismology is a complicated problem, which is due to a variety of parameters affecting the occurrence of an earthquake. Uncertainty, which is a result of vagueness and incompleteness of the data, should be considered in a rational way. Using fuzzy method makes it possible to allow for uncertainties to be considered. Fuzzy inference system,...

On November 12, 2017, at 18:18 UTC, a major earthquake with moment magnitude Mw7.3 struck the Kermanshah province of Iran, causing extended damage and casualties. Thus, we explore seismicity preceding this earthquake, with the aim to understand whether the information from past events could provide some insights about the occurrence of this and other future large earthquakes. Taking into accou...
