But if the tsunamis are continuous enough to cover the earth with water,
they are not draining off. Also, this should produce a fining outward and
upward sequence, which again is not matched by the rock record. Deep-sea
deposits are very fine-grained, contrary to what should be the case if they
were subject to extensive cratering and backwash.
