Abstract

The theory of lateral waves is reviewed in the context of long surface gravity waves and is used to interpret the results of experiments performed in a wave tank to simulate tsunami propagation following a disturbance on a continental shelf. It is suggested that since the lateral wave precedes the direct wave at coastal stations its detection might prove useful in tsunami warning systems.
