Transit
A tsunami carries your yurt and you on a stool under it away. You are now in transit.
Imagine being carried away on your stool by the tsunami, with your entire yurt floating around you too. You're both in transit... to somewhere. You don't know where though.

The transit of yourself and your yurt home is due to the water (わた). This is water transit.
You hope the tsunami's water will drop you off somewhere nice. Somewhere it's easy to jump on a different kind of mass transit, to get back home again.
