Preliminary Definition of Geophysical Regions in Western Eurasia

PDF Version Also Available for Download.

Description

The authors present a regionalized crustal model of Western Eurasia, WEA. The model is constructed using results from published studies and maps of geological and geophysical parameters in this region, and was developed in conjunction with the updated regionalization of Middle East and North Africa by Walter et al.[2000]. As this is the first realization of the Eurasian modeling effort, they have limited themselves to only twelve broad regions. Particular attention has been given to identifying the boundaries for each region. The main use of this model will be to assist in monitoring the Comprehensive Nuclear Test Ban Treaty (CTBT). ... continued below

Description

The authors present a regionalized crustal model of Western Eurasia, WEA. The model is constructed using results from published studies and maps of geological and geophysical parameters in this region, and was developed in conjunction with the updated regionalization of Middle East and North Africa by Walter et al.[2000]. As this is the first realization of the Eurasian modeling effort, they have limited themselves to only twelve broad regions. Particular attention has been given to identifying the boundaries for each region. The main use of this model will be to assist in monitoring the Comprehensive Nuclear Test Ban Treaty (CTBT). Specifically, this model will help them to calibrate and predict the travel time and amplitudes of various regional seismic phases and to locate events accurately. The model based approach allows them to readily calibrate both the seismic and the aseismic parts of western Eurasia. Each region is specified by an one-dimensional model of compressional and shear velocities, densities and layer thicknesses. Further improvements to this model will involve, but not be limited to, increasing the spatial coverage toward the east and west of Eurasia, identify sub-regions based on their distinct physical properties and the use of new and improved body wave and surface wave datasets. In the future, they expect to use this model and its successors to be the baseline model for calibration techniques, e.g., kriging, to improve their capability to detect, locate and discriminate different seismic events in Eurasia.
