Thanks ACF, I hadn't heard of that specific bolide. I have no doubt from looking at the moon and watching the night sky that there are a LOT of incoming objects big enough to cause quite a splash and that these are not low probability, large effect, events.

It's obvious that the Pacific Ocean, which is half of Earth as viewed from space, with a rim of land peeking over the edges, called The Pacific Rim is a giant bullseye.

Of course there have been regular incoming objects large enough to make catastrophic splashes. Japan has the word tsunami for a good reason.

I'd be surprised if three centuries go by without a major loss of life from a Tunguska sized splashdown. The object wouldn't necessarily actually hit the ocean. They explode when hitting the atmosphere, which causes a huge pressure wave, which is what knocked over the trees around Tunguska. That pressure wave causes a big water wave too.

Three centuries have already gone by without significant waves. Japan would have records of any good ones going back even further.

Al Qaeda is a joke compared with the danger from bolides.

After it happens, I hereby predict that governments will "find out why it happened and make sure it never happens again". They'll pass stupid laws to stop people living within certain levels of sea level and generally making a lot of nuisance, too late, shutting the stable door after the horse has bolted. Not that I'm advocating they do anything now, though information about the risk might be a good idea.
