Tsunamis induced by rock slides constitute a severe hazard to coastal fjord communities. Fjords are narrow and rugged with steep slopes, and modeling the short-frequency and high-amplitude tsunamis in this environment is demanding. In the present paper, our ability to simulate tsunami propagation and run-up in fjords for typical wave characteristics of rock-slide-induced waves is demonstrated. The simulations are compared with unique lab test data for a fjord in 1:500 scale.
