| Abstract |
Analogue experiments show that powerful eruption columns deliver material to the sea surface and seabed in periodic annular sedimentation waves. Depending on the water depth, the impact and spread of these waves at the sea surface and seabed can excite tsunamis, drive radial pyroclastic density currents, and build concentric terraces. |
