    Development of seismotectonic and ground motion parameters [microform]: working draft [ - ] Denver, Colo.: U.S. Dept. of the Interior, Bureau of Reclamation, [] Description. The Gorkha Nepal earthquake caused tremendous damage and loss. To gain valuable lessons from this tragic event, an earthquake damage investigation team was dispatched to Nepal from 1 May to 7 May A unique aspect of the earthquake damage investigation is that first-hand earthquake damage data were obtained 6–11 days after the mainshock.

Design Ground Motions. Engineers should typically use the tools below for seismic design; the parameter values they provide are not typically identical to those from hazard tools available elsewhere on the USGS website.

The USGS collaborates with organizations that develop building codes (for buildings, bridges, and other structures) to make seismic design parameter values available to. Get this from a library. Development of seismotectonic and ground motion parameters: working draft.

Epistemic uncertainties in the hazard computations are accounted for within a logic-tree framework by considering the controlling parameters like b-value, maximum magnitude and ground motion attenuationCited by: Development of Ground Motion Time Histories for Seismic Design Paul Somerville, Andreas Skarlatoudis, and Hong Kie Thio AECOM, Los Angeles, CA, USA Engineers need ground motion time histories for the analysis of the response of structures to earthquake ground Size: KB.

The seismic ground motion in the urban area of Napoli has been computed for the earthquake (M s = ) with a hybrid technique based on the mode summation and the finite difference methods.

For example, in liquefaction evaluations, the severity of shaking depends on both the amplitude of the on the topic of development of design ground motions. Based on. Resulting ground motion distributions are quantified and presented for PGA and 5 % damped spectral accelerations at T = and s, associated with return periods of and years.

Ground motion parameters are necessary for structural damage assessments and dynamic effects prediction in Las Vegas, Nevada. To develop these, a model of tectonic activity in the southern Basin and Range province was constructed on the basis of late Cenozoic patterns of crustal deformation, estimates of regional strain rates in Holocene time, and historic seismicity.

Ground water in the North Afghan Platform seismotectonic province is predominately brackish with a TDS median of ppm, and ranging from to ppm (Table ; Fig. The earthquake record and the code for designing and constructing buildings in seismic regions in Bulgaria have shown that the country is exposed to a high seismic risk due to local shallow and regional strong intermediate-depth seismic sources and that the available strong-motion database is quite limited and therefore not at all representative of the real hazard.

Design Ground Motions Ground motion parameter values for the design of buildings, bridges, and other structures. Earthquake Scenarios Earthquake scenarios describe the expected ground motions and effects of specific hypothetical large earthquakes.

Workshops Workshops are conducted periodically for input into the hazards products. Variability of ground motion intensity for a given earthquake event While the choice of a “worst-case” earthquake can be difficult and subjective, as discussed in the previous section, an even greater problem with deterministic hazard analysis is the choice of worst-case ground motion intensity associated with that earthquake.

In both deterministic and. study is in particular concerned with obtaining an estimate of the ground motion parameters at a site for the purpose of earthquake resistant design or seismic safety assessment.

This study can also be used to prepare microzonation maps of an area by estimating the strong motion parameters for a closely-spaced grid of sites. The book discusses seismicity analysis and estimation of seismicity parameters of a region at both finer and broader levels using different methodologies.

The delineation and characterization of regional seismic source zones which requires reasonable observation and engineering judgement is.

These models describe the distribution of ground motion in terms of a median and a logarithmic standard deviation (e.g., Strasser et al. This standard deviation, generally referred to as sigma (σ), exerts a very strong influence on the results of probabilistic seismic hazard analysis (PSHA) (e.g., Bommer and Abrahamson ).

The delineation and characterization of regional seismic source zones which requires reasonable observation and engineering judgement is another subject covered. The parameter space consists of all potential angles for strike, dip and rake (increment 1 degree) as well as the hypocentral depths down to 30 km (increment 1 km).

The grid search is performed based on the cross‐correlation coefficients giving a measure of the similarity between stimulated and observed waveforms [ Sokos and Zahradnik, ].The number of occurrences per year of a hazardous event (e.g.

the annual frequency that the ground-motion parameter, X, at a site exceeds a specified value x) is defined as the annual frequency and usually denoted as λ(X ⩾ x). The parameter b is the slope, which defines the relative proportion of small and large earthquakes.LOCAL SEISMOTECTONIC SETTING AND GROUND MOTIONS The recent Seismotectonic and Ground Motion Study for Seismic Stability Evaluation of DIP Phase 1 Dams (AMEC, ) indicates that the San Andreas, Berrocal, and Stanford-Monte Vista faults are the controlling seismic sources at Stevens Creek Dam.
