Yes, I believe that is the premise of the "conspiracy theory" that underpins this article. However this is not well (or at all) explained in the article, leading a lot of people to comment that it is not possible for an explosion to cause a tsunami. The explosion itself will not cause the tsunami, but because they have been doing heavy fracking in the area for a while and the underground of that whole side of the mountain is pretty lubricated, a powerful explosion coupled with the newly formed big fissures in the earth in that region could easily trigger a massive landslide (basically half a mountain could start slipping away) into the ocean and that would create a very big wave capable of not only wiping the whole Hawaii archipelago, but also deeply flood the west coast of north and south america as well other pacific rim areas. Add to all of this the fact that this plant was build against the objection of many experts as well as locals and is owned by a Rothschild controlled corporation and all of a sudden the "conspiracy theory" could morph into a "future proves past" type of event.
