If I am reading this right, they are modeling a 5ft tsunami wave on the US east cost (and much worse on the other side of the Atlantic)

On the low end, it looks like they're saying the newer models predict 5-10m (15-30ft) tsunami waves on the East Coast.

Earlier models were predicting tsunami waves of 10m to 25m (30ft to 75ft), which would likely wipe out most large cities on the coast.
