Dr. Ritima Das

About
Research Area

I am a seismologist and my research is aimed at understanding the complex structure of earth from crust down to the transition to the asthenosphere to the deep mantle from present day to the ancient processes. I am generally interested in the evolution and formation process of continent and oceans. In order to get the most comprehensive structure of the crust and mantle, I use the different tools like high resolution tomographic image using Ambient Noise and passive seismology, Joint tomography of body and surface wave, Receiver function, Joint inversion (surface wave & receiver function; body and surface wave etc), Crust and Mantle Anisotropy, deep mantle mineralogy and attenuation.
