Propagation velocities of meteotsunamis and free waves. a Propagation velocities at the centers of the triads. b Plot for propagation velocity of the first arrival versus water depth H. Curved line indicates the tsunami wave velocity \(\sqrt{gH}\), where g is the gravitational acceleration. The horizontal line represents a typical Lamb wave velocity of 0.3 km/s
