8f741d60-5b17-11e7-b40f-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 bedrock conditions (Vs30 = 760 m/s).
This scenario is for the Telek Karakhudzhur, modelled as a linear simple thrust fault Mw = 6.8 Epicentre 76.066E, 41.917N
Depth 10 km Strike 269o Dip 30o Rake 50o 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.
