NJ here. Bad advice if you are at least 20 miles inland. Stay home with maximum preps, don't end up a refugee in a FEMA camp.

The tsunami size is being greatly exaggerated. Maximum 80 feet but probably 40 is accurate. Penetration 4 to 6 miles, 10 at worst. Most fringe scenario 20 miles.

If you are 20 miles in, the greatest danger is hordes of displaced people. Do not be one of them.

95 Bridge to PA crosses below Trenton. Bad bad move. The Deleware is tidal all the way to Trenton marsh. Floods occur on the PA side usually, NJ is a high bluff mostly. You do not want to be on the roads in PA near there.

If you are really freaking out in S Jersey, look up Arneys Mt. It's really a hill, but over 200 feet.
