GMPE-estimation implements a one-stage estimation algorithm to estimate ground-motion prediction equations (GMPE) with spatial correlation. It also quantifies the uncertainty of spatial correlation and intensity measure predictions.

2013年12月3日 · Ground motion prediction equations (GMPEs) relate ground motion intensity measures to variables describing earthquake source, path, and site effects. From many...

The first type of these graphs (Figure 1) show predicted response spectra (color/line style coded for each GMPE) where each graph within the trellis has an x-axis of period and a y-axis of...

2023年10月5日 · This package contains commonly used Ground Motion Prediction Equations (GMPE). It includes five NGA-West2 Models (ASK14, BSSA14, CB14, CY14, and I14) for crustal earthquakes; and four (BC Hyrdo 2011 + 2019, Zhao et al 2016, Parker et al 2020 NGA-Subduction) for subduction earthquakes, and one NGA …

2024年2月1日 · We first evaluate the inherent quality of local GMPEs, with respect to their underlying datasets, the variables used and their functional forms, to determine a set of candidate GMPEs. Then we investigate how well the predictions from the GMPEs match observations computed from strong-motion records of recent earthquakes in this area.

2024年8月25日 · This online resource summarizes all empirical ground-motion prediction equations (GMPEs), to estimate earth?quake peak ground acceleration (PGA) and elastic response spectral ordinates, published between 1964 and 2023 (inclusive).

2019年3月1日 · In this study, new GMPEs are derived for a total of 21 parameters representing peak amplitude, energy, intensity, frequency, duration and evolutionary characteristics of a ground motion acceleration time history.

Each developer team chose different functional forms for the GMPEs, in order to capture effects that they thought should be modeled. The functional forms are a tradeoff between simplicity of use and being able to represent the complexity in ground motions, due to many physical effects.

2017年3月2日 · Graizer-Kalkan (2015) ground motion prediction equation (GMPE) is designed to predict peak-ground acceleration and 5% damped pseudo-spectral acceleration response ordinates for shallow-crustal continental earthquakes to be used in earthquake-engineering applications including probabilistic and deterministic seismic hazard analyses.

2013年10月1日 · Region specific Ground Motion Predictive Equation (GMPE) is an important input in the seismic hazard analysis for macro- and micro-zonation studies. Few GMPEs developed in India are based on the recorded data and are applicable for a particular range of magnitudes and distances.
