A systematic tutorial introduction to the finite-difference (FD) numerical modelling technique for professionals, academic researchers, and graduate students in seismology.
Peter Moczo is a professor of physics and Chair of the Department of Astronomy, Physics of the Earth, and Meteorology at Comenius University, Bratislava. He is the main author of several monographs and extended articles on the finite-difference method (including the highly-respected Acta Physica Slovaca article which partly forms the basis of this book). Professor Moczo is a member of the Learned Society of the Slovak Academy of Sciences, and his awards include the Prize of the Slovak Academy of Sciences for Infrastructure, the Silver Medal of the Faculty of Mathematics, Physics and Informatics of Comenius University, and the Dionyz Stur Medal of the Slovak Academy of Sciences for Achievements in Natural Sciences. Along with his two co-authors, Professor Moczo is a leading member of the (informal) NuQuake research group, studying numerical modelling of seismic wave propagation and earthquake motion, at Comenius University and the Slovak Academy of Science in Bratislava. As part of this group, all three authors were major contributors to the elaboration of the finite-difference method and hybrid finite-difference/finite-element method.
