3D Modeling of Iran and Surrounding Areas from Simultaneous Inversion of Multiple Geophysical Datasets (Postprint). Annual Report 3
Abstract
The objective of this work is to help improve seismic monitoring technology through the development and application of advanced multivariate inversion techniques to generate realistic, comprehensive, and high-resolution 3D models of the seismic structure of the crust and upper mantle that satisfy independent geophysical datasets. The focus is on the region surrounding Iran from the east coast of the Mediterranean in the west, to Pakistan in the east, a region with adequate calibration events to validate our model and to quantify its accuracy. Specifically, the effort is to integrate surface-wave dispersion, receiver function, and satellite and ground-based gravity observations to help constrain the shallow seismic structure in the Arabian-Eurasian collision zone. Building on earlier work combining receiver functions and surface wave dispersion, and surface-wave dispersion and gravity, integration of geophysical data sets will continue to create more broadly compatible earth models. Geologically based smoothness constraints will be explored to help resolve sharp features in the underlying shallow 3D structure.
