The hazards are related to two basic phenomena resulting from the failure of a geological fault. Seismic Risk Analysis Assesses the probability of occurrence of losses (human, social, economic) associated with the seismic hazards. Fig. But we have to know about seismology (Figure A) and tectonic (Figure B) of our study area to detect the correct model. Figure 3. Some of these will be easy to identify (e.g., a known active fault); others may be more difficult to describe. Norm Abrahamson, UC Berkeley. Two basic methodologies used for the purpose are the "deterministic" and the "probabilistic" seismic hazard analysis (PSHA) approaches. Seismic Hazard Analysis (PSHA) with fragility (probability of failure) of the dam and the . The investigative loom to PSHA was initialially Target Spectra Development Develop design or analysis target spectra using a deterministic seismic hazard analysis (DSHA) or probabilistic seismic hazard analysis (PSHA) in accordance with the design or analysis criteria. deterministic and probabilistic seismic hazard analyses. The first step in the conventional PSHA is the identification and characterization of the seismic sources. Deterministic seismic hazard analysis gives a cap value for the Probabilistic Seismic hazard analysis. Four steps of deterministic seismic hazard analysis (Kramer, 1996) 1. In the present study, Earthquake hazard maps for the Constantine region are . 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 The case study about the seismic hazard in Yunnan Province in China is in vestigated in Chapter 4. casting large earthquake. Identification and characterisation of all earthquake sources capable of Pfail for 7, 3 and 1 Level Seismic Hazard Levels . Our short 6-week PSHA course was so popular last year, we've been asked to provide a full length 40-hour version for those looking to deepen their knowledge of Probabilistic Seismic Hazard Analysis. Probabilistic Seismic Hazard Analysis Tenzin Yangkey Duke University December 15, 2019 Abstract Probabilistic Seismic Hazard Analysis (PSHA) has been used widely over the last 50 years by seis-mologist and engineers to quantify seismic hazard level and develop building code requirements to build safer buildings for the future. FIGURE 13.1 The four steps of probabilistic seismic hazard analysis (PSHA). Identification and characterization of all earthquake sources capable of producing significant ground motion at the site. The first step is to identify all the possible sources of ground motion. Deterministic seismic hazard analysis was the first method- ology developed; it comprises four steps (Reiter 1990): 1. About 21 numbers of faults and lineaments are identified as a vulnerable sources as a first step. The study region is one of the most seismically active regions of western part of Himalaya, India and there are numerous major . seismic hazards. RIZZO provides deterministic and probabilistic seismic hazard analyses and calculations of corresponding ground motion levels and response spectra for use in building analyses, fragility analyses, and seismic risk quantification for nuclear power plants, dams, and other critical infrastructure. Now I would like to compute deterministic seismic hazard (DSHA) results in order to compare the results with PSHA. Identification and characterization of all sources 2. The PSHA can also be described as a procedure of four steps each of which bear some Deterministic Seismic Hazard Analysis Consists of four primary steps: 1. Usually the earthquakes are assumed to occur on the portion of the site closest to the site. Deterministic Seismic Hazard Analysis A specific seismic scenario is developed and the assessment of ground motion hazard is made accordingly. Compute epistemic uncertainty variability from Steps 1 and 2 . 3: Steps for Deterministic Seismic Hazard Analysis (DSHA) 2.2 Probabilistic Seismic Hazard Assessment (PSHA) But Seismic Hazard Evaluation Conduct seismic hazard deaggregation to determine dominant seismic sources and characteristics. Seismic HazardAnalysis Services. The study area is Erzincan, which is a city on the eastern part of the North Anatolian Fault Zone. For the past two decades, the discussions are based mainly Identification and characterization of all sources Selection of source-site distance parameter Selection of controlling earthquake Key words: Deterministic hazard analysis, estimation of the strong earthquake ground motion at a site of interest, Republic of Serbia 1. Main components of this study are construction of local seismic velocity models, probabilistic and deterministic seismic hazard analyses, and estimation of corresponding potential ground motions. Typically, they can be defined as four procedures (Reiter, 1990): (c) Characterize the distribution of source-to-site distances from each source. Following are the steps in hazard assessment: 1. Seismic hazard analysis is an approach to describe the po-tential shaking intensity for future earthquakes, which can be estimated by deterministic or probabilistic approaches. This research has developed a deterministic seismic hazard analysis method using fuzzy logic for estimating seismic hazard potential in each range. The hazard analysis was done using two different source models (linear sources and point sources) and 12 well recognized attenuation relations consider- Confirm that the fault rupture hazard exists by repeating some or all of the preliminary screening performed by the Geoprofessional. If the 1.e-4 annual seismic hazard probability is considered, then, the "conventional" deterministic SSI results based on DRS input, should be increased by the ratio between In the 1960s and 1970s, the DSHA was used as the main type of seismic hazard analysis, but it has been gradually replaced by the PSHA. These regions are shown in Figure 3.1 and Figure 3.2 respectively. I have a set of ground-motion prediction equations. previous section, an even greater problem with deterministic hazard analysis is the choice of worst-case ground motion intensity associated with that earthquake. The computation of seismic hazard and probability of occurrence of ground motion levels during a specified period of time using the integration of the above three steps over all possible magnitudes and earthquake locations. Deterministic and probabilistic seismic hazard analysis; Site-specific ground response characterization; Seismic hazards are potentially dangerous conditions arising from the occurrence of earthquakes. - Deterministic Seismic hazard analysis (DSHA) Initial approach taken to seismic risk investigation discovered in nuclear power engineering applications In Deterministic Seismic Hazard Analysis (DSHA), is organized for a meticulous earthquake, also realistic or assumed. Different earthquake hazard maps must demonstrate their capability in anticipating ground shaking from future strong earthquakes before an appropriate use for different . Use of PSHA could lead to either unsafe In the present study Deterministic Seismic Hazard Analysis (DSHA) has been carried out for the states of Himachal Pradesh & Uttarakhand. DETERMINISTIC SEISMIC HAZARD ANALYSIS (DSHA) © 2021 29 •Ground shaking hazard is assessed by identifying a specific earthquake "event scenario" -one for which the combination of magnitude and distance (together with other pertinent source and site parameters) provide large levels of ground shaking After Fernandez, 2010 (GMPE) SEISMIC HAZARD. Deterministic Seismic Hazard Analysis (DSHA) In the early years of earthquake engineering, deterministic seismic hazard analysis (DSHA) was widespread In DSHA the hazard is evaluated based on a particular seismic scenario (Kramer, 1996) The DSHA can be described as: 1. This hazard includes effects of both the regional tectonics and the local site characteristics. (b) Characterize the distribution of earthquake magnitudes from each source. Some of these will be easy to identify (e.g., a known active fault); others may be more difficult to describe. The basic steps in deterministic seismic hazard analysis include 1) defining earthquake source zones, 2) selection of the controlling earthquake which could be the earthquake which is reasona-bly expected or the maximum credible earthquake, 3) determination of the SEISMIC HAZARD The seismic hazard can be . Uganda is situated between the two seismically active branches of the East African Rift Valley System, which are characterized by high levels of seismicity. Both approaches can be defined in a four-step process, and their initial steps are identical (Reiter 1990 ). Seismic Waves. hazard analysis, the deterministic and the probabilistic seismic hazard analysis. Seismic hazard analysis is an approach for obtaining estimates of future earthquakes. The neo-deterministic approach allows to: . Further, Chap-ter 3 introduces the proposed method for fuzzy-probabilistic seismic hazard analysis. All webcasts will be recorded and available on CalGeo's new On-line Learning Library for course attendees. Identification of the Type of Hazard: The first stage in hazard analysis is to identify the types of hazards. The steps involved in both deterministic seismic hazard analysis (DSHA) and probabilistic seismic hazard analyses (PSHA) are outlined in Chapters 4 and 5 , respectively. . The Chapter 5 provides the con clusions and further research. Four-steps process of a deterministic seismic hazard assessment 2- Case Study of Kerman As a case study, DSHA of . 1. Norm Abrahamson will present a 6-week short course for CalGeo on Site Specific Seismic Ground Motion Hazard Analysis. INTRODUCTION There are two basic philosophies for the seismic hazard analysis, the so-called deter-ministic seismic hazard analysis (DSHA) and the probabilistic seismic hazard analysis (PSHA). The data was shortened for records less than Mw=4, because this. DSHA basically four step process which is shown in the figure.1. The purpose of this study was to conduct seismic hazard analysis for Al-Tajiat and Al-Zawraa stadiums using probabilistic and deterministic approaches. This is due to the reduced damping value in Deterministic SSI analysis (4% damping) than in Probabilistic SSI analysis (random values > 4%). ! Deterministic seismic hazard analysis (DSHA) has been applied to Dhamtari and Kanker sites using the following steps: A region of 300 km radius around both Dhamtari and Kanker sites were considered and all the faults having 25 km length were marked. However, using the Deterministic Seismic Hazard Analysis (DSHA) no further information is provided about the expected level of shaking or fault activation during pipeline life-cycle, the earthquake occurring probability and the effects of From either a deterministic or probabilis- tic viewpoint, this design step is perhaps the best developed. SSI analysis and "conventional" deterministic SSI analysis results depends on the seismic hazard level considered for the probabilistic simulations. Basic Steps in Probabilistic Seismic Hazard Analysis Seismic source characterization Estimation of source seismicity parameters (recurrence) parameters and probabilistic model Selection of ground motion attenuation models Treatment of Epistemic Uncertainties with Logic Tree Models Quantification of the seismic hazard . Dr. (Bommer, 2002). methodology followed for Deterministic Seismic Hazard Analysis (DSHA) is described as four steps and illustrated in Figure 5. Approaches to Seismic Hazard Analysis Deterministic The earthquake hazard for the site is a peak ground acceleration of 0.35g resulting from an earthquake of magnitude 6.0 on the Balcones Fault at a distance of . In the context of a probabilistic ground motion analysis, hazard refers to the probability of exceedance certain amplitude of ground motion. The stadiums of Al-Tajiat and Al-Zawraa are located at latitude of $${33^{\\circ}}$$ 33 ∘ 25ʹ25.80ʺN, longitude of $${44^{\\circ}}$$ 44 ∘ 17ʹ9.28ʺE and latitude of $${33^{\\circ}}$$ 33 ∘ 20ʹ39ʺN, longitude of $${44^{\\circ}}$$ 44 . Seismic hazard of engineering structures determines the probability of exceeding a specific level of damage or loss due to potential hazardous . An interdisciplinary approach was adopted by integrating: (1) historical data; (2) co-seismic geological effects in terms of . deterministic seismic hazard analysis (DSHA), are commonly used for seismic hazard assessment. Seismic Hazard Assessment Methodology To access the seismic parameters, a probabilistic or deterministic methodology is necessary. provided by pattern recognition analysis. applications, seismic hazard analysis can also be used to prepare macro or micro zoning maps of an area by estimating the strong-motion parameters for a closely spaced grid of sites. The last session will be Friday June 26th, 2020.

Seismic hazard in an area can be estimated by either the probabilistic seismic hazard assess-ment approach (PSHA) or the deterministic seismic hazard assessment approach (DSHA) [ ]. In this study, seismic hazard zoning for the Anzali Port and its surroundings were determined by using fuzzy logic. Presented by Dr. develop the uncertainty associated with each step 5) develop the seismic hazard curves and uniform hazard spectrum/ conditional mean spectrum. Depending on the types of hazards identified, the process may need to be continued on a separate basis for each type of hazard or group of hazard types. The seismic hazard at a site can be quantiied by undertaking deterministic or probabil-istic seismic hazard analysis (PSHA) (Erdik 2017). Neo-deterministic seismic hazard assessment - NDSHA Account for uncertainties and gaps in the available observations, by considering a wide set of scenarios and parametric tests. The choice of method must be selected based on site characteristics, seismicity of region and the availability of data and future applications. Brigham Young University BYU ScholarsArchive Theses and Dissertations 2016-07-01 Simplified Performance-Based Analysis for Seismic Slope Displacements The aim of probabilistic seismic hazard analysis (PSHA) is to measure the probability of over and above range of ground action levels at a site given all probable earthquakes. 1. A deterministic seismic hazard analysis approach to determine PGA was adopted. 2.4 Schematic illustration of the basic five steps in probabilis-tic seismic hazard analysis. Seismic Hazard Analysis. Deterministic seismic hazard analysis (DSHA) has been applied to Dhamtari and Kanker sites using the following steps: A region of 300 km radius around both Dhamtari and Kanker sites were considered and all the faults having 25 km length were marked. Seismic hazard analysis involves the quantitative estimation of ground shaking hazards at a particular area. 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. (a) Identify earthquake sources. Objective testing is the key issue towards any reliable seismic hazard assessment (SHA). Main steps are written below (Kramer, 1996). Based on the minimum distance from the site to the fault source, the level of ground shaking at the site is estimated. Steps in Deterministic Seismic Hazard Analysis (1) Sources (3) Ground Motion (4) Hazard at Site These are the basic steps in the deterministic analysis. www.intechopen.com Probabilistic seismic hazard analysis offers a rational framework to describe elastic seismic demand in terms of peak ground motions and response spectra, and addresses key uncertainties and dependence in earthquake occurrence (both temporal and spatial), earthquake magnitude, rupture characteristics, and ground motion intensities (see Chapter 1 ). Seismic hazard analysis is an approach for obtaining estimates of future earthquakes. Any physical phenomenon ( e.g. Both approaches use the samedatasets,whichincludeearthquakesources,occurrence frequencies, and ground motion attenuation relationships. The site ground motions are estimated deterministically, given the magnitude, source-to-site distance, and site condition. Steps in Deterministic Seismic Hazard Analysis (1) Sources (3) Ground Motion (4) Hazard at Site These are the basic steps in the deterministic analysis. !%) The assessment was based on the environmental effects that had effectively contributed to the high destructive impact of that event. In the scenario earthquake, there is a precondition for an earthquake of a certain size and location to occur. These sources may be in the form of point, line or area seismic source zone. In this study, seismic hazard zoning for the Anzali Port and its surroundings were determined by using fuzzy logic. Conclusions. Earthquake hazard may be analysed in two main ways: deterministically, in which a single (usually) most adverse earthquake scenario is identified, or probabilistically, in which all-potential earthquake scenarios are explicitly considered along with their likelihood of occurrence. 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. Our research is a contribution to improving the seismic risk management by evaluating the seismic hazard in the North-East Algeria. 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). The first is based on the seismic history, on the return period concept, and on the knowledge of existing faults, capable or not, and does not account for high mag-nitude events, whose occurrence has been assessed in the prehistoric age. quake originating from nearby fault. Step 2: Surface Fault Rupture Displacement Hazard Analysis If a hazard exists, perform the Surface Fault Rupture Displacement Hazard Analysis, which includes determining the magnitude and direction of anticipated I have a set of simple fault sources whose have a specific magnitude value, style-of-faulting (i.e. In the deterministic approach, a par-ticular earthquake scenario, called controlling earthquake, is used to estimate hazard at a site. Seismic hazards can be analyzed deterministically as and when a particular earthquake scenario is assumed, or probabilistically, in which uncertainties in earthquake size, location, and time of occurrence are explicitly considered (Kramer, 1996). (d) Predict the result-ing distribution of ground motion . The tradition standards-based al . This research has developed a deterministic seismic hazard analysis method using fuzzy logic for estimating seismic hazard potential in each range. ANALYSIS SEISMIC HAZARD • Defined as a natural phenomenon (such as ground shaking, fault rupture, or soil liquefaction) that is generated by an earthquake, although there are examples of these phenomena also being produced by human activities. 360 Earthquake Hazard, Risk, and Disasters specific application of PSHA at a site, such as the types of earthquake sources, The response spectra plotted in Figure 1.2 are the median1 spectra predicted by empirical models calibrated to recorded ground motions. A probabilistic seismic hazard analysis requires the availability of an earthquake catalog, relevant ground motion prediction . characteristic earthquake, at a specific location. Seismic hazard can be quantified by adopting two globally accepted techniques: the deterministic seismic hazard analysis (DSHA) and the probabilistic seismic hazard analysis (PSHA) approaches. Diagrams showing four steps of probabilistic seismic hazard analysis [3]. DSHA is often used in California due to the familiarity of faults and the region's elevated seismicity. The deterministic approach estimates the intensity measure am-plitude (e.g., peak ground acceleration (PGA) as 0.2g) un- Seismic hazard analysis involves the quantitative estimation of ground shaking at a particular site or for a particular region. Step 4 Neo-Deterministic and Probabilistic Seismic Hazard Assessments: a Comparative Analysis. The results obtained from the PSHA will complement the results from the deterministic approach by providing a complete picture of the seismic hazard. the probabilistic seismic hazard assessment (PSHA) and the deterministic seismic hazard assessment (DSHA). Seismic hazard analysis should integrate both the deterministic and probabilistic characteristics of a region, since exclusion of effective factors result in misled judgment and prediction. The first step is to identify all the possible sources of ground motion. The hazard at the site is formally defined, usually in terms of the ground motions produced at the site by the controlling earthquake. Wang and C. Cobb, "A critque of probablistic versus [33] E.
