Those areas wouldn't be underwater very long, and farther inland the water would not be very deep, but the issue would be with the infrastructure that would be destroyed, the lives lost closer to shore, and also the economic impact of have the ports on the East Coast wiped out.

No..... I mean explosives could be placed in the volcano crevasse to encourage the inevitable......but the kind people running the world would never be so evil, I'm sure.
There is an (unproven) theory that the Indonesian tsunami was caused by a nuke placed in between irregularly shifted tectonic plates in the Indian Ocean. I guess anything is possible.
I submit that most "acts of God" are really works of satan these days.

IMHO, any story like this is likely fαℓѕє fℓαg preconditioning.

Hollywood zionists produced various movies about planes crashing into skyscrapers prior to 911.  
Christopher Bollyn definitely proved this.


Timing wise, the ʝʊdɛօ-masons need a distraction, since their vax-genocide is starting to falter, as Gentiles finally become "woke" to their fake science.

I know Asian trad Catholics who firmly believe the 2004 Indian Ocean earthquake and resulting tsunami were man made (230,000 dead).

There's also ample proof that Israel was involved in the Fukushima earthquake & tsunami. 

Israel owns several German Dolphin Class submarines that are capable of delivering nuclear payloads, of which they have many.  



In addition, it was revealed that the Fukushima nuclear reactor that exploded "Hollywood style", was under the control of Israeli (mossad) security.


Tell me a tsunami is imminent... and I'll reply, "Be on the look-out for the Israeli Navy!".

True, but how long would they stay that way?  Wouldn't rainfall and percolation of that rainwater eventually dilute the salinated water?
