An improved high-resolution shear velocity model beneath the Iranian plateau using adjoint noise tomography
Abolfazl Komeazi, Ayoub Kaviani, Farzam Yaminifard +2
We perform an adjoint waveform tomography using Rayleigh wave Empirical Green's Functions (EGFs) at 10-50 s periods to improve a prior 3-D velocity model of the crust and uppermost…

When linear inversion fails: neural-network optimization for sparse-ray travel-time tomography of a volcanic edifice
Abolfazl Komeazi, Georg Rümpker, Johannes Faber +2
In this study, we present an artificial neural network (ANN)-based approach for travel-time tomography of a volcanic edifice. We employ ray tracing to simulate the propagation of s…
