V. A. Dziewonski

V. A. Dziewonski was a renowned geophysicist known for developing methods to study Earth's interior using seismic waves generated by earthquakes. His work helped create detailed models of Earth's inner layers, such as the core and mantle, by analyzing how seismic waves travel through the planet. This research deepened our understanding of Earth's structure and composition, contributing significantly to geophysics and Earth sciences. Dziewonski's innovative techniques have been fundamental in advancing seismic tomography, allowing scientists to visualize the Earth's interior with greater clarity.
