Numerical Modeling in Seismology: Theory, Algorithms and Applications
Progress in seismology is unthinkable without continuous developments of theory and numerical-modeling methods. Recent advances in finite-difference, discontinuous-Galerkin, spectral-element and distributional finite-difference methods prove the irreplaceable role of numerical modeling in investigation of earthquake source, earthquake ground motion, seismic ambient noise, and Earth’s structure.
We equally invite contributions to numerical-modeling methods and efficient computational algorithms, both in all dimensions, and applications to earthquake phenomena and specific sites of interest. We invite contributors to share their advances in the numerical modeling and understanding of seismic wave propagation, earthquake rupture, earthquake ground motion, and seismic ambient noise. Better understanding of physics of these phenomena based on new observations, seismic data from dedicated networks, and efficient numerical modeling should eventually help to progress in predicting earthquake ground motion.
Recent developments in numerical modeling of seismic waves, earthquake ground motion and rupture propagation aim to account for more realistic rheology as well as geometrical complexity of material interfaces and faults. They also address discretization in time and space and their relations to accuracy and computational efficiency. Remarkable progress in the efficiency and accuracy of finite-difference modeling in seismic exploration poses a useful challenge for numerical modeling in earthquake seismology.
We especially welcome applications to compelling observational issues in seismology.
