Scenario hazard map for the Telas Ferghana (east) fault system in Peak Ground Acceleration (PGA) expressed as fractions of g (gravitational acceleration) for bedrock conditions (Vs30 = 760 m/s)
The 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 Telas Ferghana (east), modelled as a linear simple strike slip fault Mw = 7.8 Epicentre 73.840E, 41.235N Depth 10 km Strike 310o 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. - Akkar, S., Sandıkkaya, M.A. and Bommer, J.J.
