6781be5c-5b17-11e7-8f01-5a0ae85bcf4aThe Kyrgyz Republic is located within a region of high seismic hazard, a result of the ongoing collision between India and Asia. This dataset represents the hazard resulting from a scenario in terms of Peak Ground Acceleration (PGA) expressed as fractions of g (gravity acceleration) for site conditions defined by the USGS Vs30 model. This scenario is for the Talas Ferghana (west), modelled as a linear simple strike-slip fault Mw = 7.8 Epicentre 71.951E, 42.074N Depth 10 km Strike 297o Dip 70o Rake 170o The values have been computed on a grid of 0.5 degrees covering an area within 200 km of the modelled fault system. The results are provided in WGS84-UTM43N projection. They are presented as percentiles (5th 25th 50th 75th 95th) determined from a total of 3000 calculations, made up of 1000 calculations from each of the three Ground Motion Prediction Equations (GMPEs) used.
