I find this hard to believe. Chances are these would be landing in the oceans somewhere. Wouldn't an impact of that magnitude cause tsunamis?

A tsunami can't really be generated at the surface unless it was really, really, big.
We've detonated nuclear weapons underwater that haven't caused it.
To make a tsunami, the origin would have to be close to the bottom as possible.
Remember they are generated by displacement of a large column of water. That is different from a wave that a surface impact would make.
