"This was purportedly caused by a landslide event i.e. a slosh. Undersea events cannot cause waves this high."

I think that depends on the size of the undersea event. Incidentally this "slosh" is what would happen if the 20 mile chunk of Las Palmas were to let go in the Atlantic. Many experts think it, (the Las Palmas Volcano) couldn't cause tsunamis either.

I think what is possible depends on which expert you talk to. I suspect almost anything is 'possible' under the right circumstances.

" I think that depends on the size of the undersea event"

My recollection of the explanation is that undersea events are the result of plate tectonics and never shift more than dozens of feet, not thousands of feet, therefore they cannot cause waves of the 1700 foot variety.
