Abstract

We compare two high order finite-difference methods that solve the elastic\nwave equation in two dimensional domains with curved boundaries and material\ndiscontinuities. Two numerical experiments are designed with focus on wave\nboundary interaction, the response of a pressure wave impinging on a circular\ncavity and the wave field generated by an explosive impact on the wall an\nunderground tunnel. Qualitative comparisons of the results are made where\nsimilarities and differences are pointed out.\n
