Numerical Methods in Geophysics: Present, Future, and Applications

Home

This event will cover some of the latest advances in numerical methods with applications to geophysics. Particular emphasis will be given to novel advances in Artificial Intelligence methods and future perspectives on their applications in geophysics. Besides, this will be the last yearly scientific meeting of the European’s Union Horizon 2020 Project MATHROCKS.
