Around 1945 there was military operation called 'Project Seal' that took place in New Zealand. It involved placing bombs underwater to create waves like tsunami. They did produce small waves that didn't cause damage like what we know from the recent quake induced ones off India and Japan. These people in-charge of the experiments were able to predict that tsunami and the timing well.
The man in question with the huge quake and tsunami may be sensing something by intuition or creating something to make profit. It doesn't matter. But it is a known fact that the large militaries would try anything to keep up their strengths and do all kinds of research and testings, including creating quakes and tsunamis.
When you look at what happened after the Indian ocean tsunami, it makes you wonder about things. Within a day or two after, the US government wanted India to be a part of the US, UK, Australia navies and another country to form some sort of alliance to do relief. Strangely the Indian government refused to join in, and then also demanded those navies to stay out of our territorial waters.
The US agency that monitors quakes around the world pointed the epicenter of the quake to one place, then another, and again to another place till finally it was about 80 km away from the original place.
The seismographs that record quakes show differing patters for an earthquake, and for an explosion. You can see for yourself the recordings available online.
The earthquake and tsunami attributed to the Japanese incident in 2011, again there are discrepancies the narrative given. One can never confirm this officially but there were clashing business and commercial interests against Japan getting fully self-sufficient for all its energy needs by nuclear energy. The nuclear plant in Fukushima is believed to be a target.
Will there be a huge quake or tsunami? Yes, it is likely possible but not of natural causes. Let us not blame mother nature for what wicked man does and can do yet.
