Well, the Tunguska meteorite was larger and disintegrated before touching ground (no crater was ever found in spaite of all the flattened trees), so guess that this one, significatively smaller, would have not caused so much damage unless it fell right on top of a city. No real risk of tsunami for a meteorite that disintegrates before touching the sea, and falling into the sea is the most likely thing to happen to any such thing falling on Earth, as seas are like 70% of the surface. Even if it managed to fall on land, there's a huge chance that it'd fall in a desertic or ill-populated area, like the Sahara or Central Australia.

The chances of such thing falling on a large city are very small. The real problem would be if it'd be a larger object which would actually make impact, then we could expect a tsunami or some other problem with some likelihood. If the object is pretty large, then we would have real problems no matter where it lands, as such an impact could cause earthquakes and huge volcanic eruptions in the opposite side of the Earth crust, what would lead to a global climatic catastrophe.
