A)Formation of a lahar flow

D)Deposition of pumiceous breccia

A sudden introduction of heat from pyroclastic flow causes explosive boiling and displacement of water, a process called phreatomagmatic eruption; therefore, a tsunami can initiate, rather than simply lahars or submarine slides, because energy focusing is key.
