The waves were 6.9m high, which is as high as that horizontal line on the blue sign.

As you can see, you’d be only be 1/5 of the height. Anything above 1m is considered lethal, as the height of tsunamis is measured is the part of the waves that is completely water, and not the bit that sticks out from the minimum height.
