What the record says

NCEI’s account, from the sources it cites.

The simultaneity of the earthquake and submarine slumping is corroborated by eyewitness reports that described a wave that rose suddenly in the middle of the Dead Sea and piled water 1m high along its north shore. The displaced bottom mass generated by the slump event would have provided the impulse for the observed wave. An eyewitness described the wave as moving northward from a point within the middle of the north Dead Sea basin. This evidence supports the interpretation that the wave was caused by the slumping rather than by an oscillation of the lake level-ie., a seiche. (reference #4705)
