Venezuela and other South American countries bordering the Caribbean and Central America must take more avoiding volcanoes and seeking high land into consideration during the shift, as the Caribbean and Central America will crumble during the plate slamming that occurs during the shift, giving way so that water pressure will rush between the Atlantic and Pacific as through a sluice. Rapidly disappearing Caribbean plates will create a sudden compression in water over those plates, which will have nowhere to go. When the Pacific shortens, the gap created by a crumbled Central America will allow a rush of water toward the Atlantic, the speed of the water intensified by the narrow sluice through which it runs. Coastal countries bordering this nightmare need to move well inland and into high ground, beyond the normal recommendation of 100 miles inland and 200 miles above sea level. The farther inland, the better, or the nightmare may be upon you.
Tsunami are generated anytime a plate drops or rises under the sea. When the S American Plate rolls, it will push the Caribbean Plate down, creating a void. The void will primarily be at the southern part of the Caribbean Plate, where islands will suddenly lose elevation, some sinking entirely. This void will pull water from the Caribbean as well as the Atlantic, which would seem to negate the likelihood of a tsunami, but there will be a clash. When the water rushes into the void it is water on the move, with momentum, and this is the tsunami expected along the coastline of Venezuela and its neighbors. This coastline will at first find water receding, but this is a false signal and should not be trusted. The wave will be coming. The islands will have no such warning, but will sink suddenly in concert with the quakes.
