These two methods can complement each other, thus providing additional insights into the question of seismic hazard. The hazard analysis was done using two different source models (linear sources and point sources) and 12 well recognized attenuation relations consider- In the present paper seismic hazard analysis has been presented using deterministic method. Hence, in the present study, deterministic seismic hazard analysis (DSHA) for the Greater Mumbai region (lat. Read Paper. The deterministic analysis considers one source, one magnitude and one distance at a time. Approaches to seismic hazard assessment can be grouped into two broad categories: Deterministic (DSHA) and Probabilistic (PSHA)[10]. of Energy (DOE) an acceptable probabilistic seismic hazard analysis (PSHA) approach for identifying and assessing the hazard of vibratory ground motion and differential fault displacement. The seismic hazard at Vandenberg AFB was investigated using both statistical analysis of the temporal and spatial distribution of historic earthquake activity within 500 km of Point Arguello, California, and deterministic methods based on knowledge of earthquake faults and Seismic hazard analysis is an approach for obtaining estimates of future earthquakes. Main point of deterministic Seismic hazard analysis is the determination of the peak ground acceleration (PGA) and spectral acceleration for the particular region. Seismic hazard analysis for safe and economic design of structures is important for Mumbai for earthquake disaster study and mitigation. Typically, the analysis is based on the largest earthquake that the fault is considered to be capable of (i.e., its maximum magnitude). Deterministic and probabilistic seismic hazard analysis; Site-specific ground response characterization; Seismic hazards are potentially dangerous conditions arising from the occurrence of earthquakes. The city of Corinth has been chosen due to its seismic history. It can provide theoretical basis and technical reference for doing further research of tsunami hazard analysis in China. Deterministic Seismic Hazard Analysis (DSHA) Krinitzsky (2005) highlights that a Deterministic Seismic Hazard Analysis (DSHA) uses geology and seismic history to identify earthquake sources and to interpret the strongest earthquake each source is capable of producing regardless of time, because that earthquake might happen tomorrow. 3. Seismic Hazard Among the possible definitions of seismic hazard analysis, [9] describes it as the estimation of some measure of the strong earthquake ground motion expected to occur at a selected site. The key differences between probabilistic seismic hazard analysis (PSHA) and deterministic seismic hazard analysis (DSHA, preferably referred to as a scenario-based analysis) are that, unlike DSHA, PSHA takes account of all magnitudes on all earthquake sources that may affect the site, including the frequency of occurrence of each … Deterministic Seismic Hazard Analysis (DSHA) In DSHA, the maximum magnitudes (maximum credible earthquake, MCE) for the earthquake sources (point, line or area) related to the site are determined considering geological and seismotectonic characteristics. The deterministic method To perform a deterministic seismic hazard analy- sis (DSHA) for a critical engineering project, where the consequences of failure are intolerable, one generally does the following: Step 1: Establish the location and characteristics of all significant potential earthquake sources that might affect the site.

Derivation of IBC Design Maps The ground motions for design that are mapped in the IBC are based on, but not identical to, the USGS Probabilistic Seismic Hazard Analysis (PSHA) Maps for … 2% in 50 years probability of exceedance 0.2- and 1.0-second spectral acceleration (SA) The site-specific ground motion procedure in the building code explains the link between the two. Although PSHA has been pro-claimed as the best approach for seismic hazard assessment, it is scientifically flawed (i.e., the physics and mathematics that PSHA is based on are not valid). assessment methodologies, most seismic hazard assessments were completed using scenario-based, “deterministic” analyses. The first step is to identify all the possible sources of ground motion. Seismic hazard analyses completed by the LCI team, typically include acquisition and interpretation of field data combined with state-of-the-art analysis to calculate engineering results to inform analysis and design decisions. Many earthquakes have been knowledgeable in Indian peninsular shield, which was previously treated to be seismically steady. The Deterministic Seismic Hazard approach uses the identified seismic sources suitably by the accessible historical seismic and This Paper. This approach has been labeled deterministic seismic hazard analysis (DSHA) and has been used for many years in the design of power plants, large dams, and other critical facilities. Instructional Material ComplementingFEMA 451, Design ExamplesSeismic Hazard Analysis 5a - 3 Seismic hazard analysis describes the potential for dangerous, earthquake-related natural phenomena such as ground shaking, fault rupture, or soil liquefaction.
