TSUNAMI FORMATION:
Stage 1—Beginning: If the tsunami acts like
an earthquake, the sea floor is moved up or
down. As a result the mass of water moves
up or down.
Stage 2 —Separation: Within a few min-
utes, the tsunami that starts to form divides
in two, one part moving toward the depths
of the ocean, the other reaching the coast.
Stage 3—Elevation: The tsunami wave
reaching the shore rises up like a huge
wave when it reaches the land.
Stage 4- Wave impact: The leading wave
becomes pointed and appears to rise even
higher. The first part of the wave to hit the
land is convex in shape, which is why the
water initially seems to be pulling away
from the land.
During the 1993 tsunami attack on Okushiri, Japan, the wave "run
up" on the coast averaged about 15 to 20 meters (50 - 65 feet). But in
one particular spot, the waves pushed into a V-shaped valley open
to the sea, concentrating the water in a tighter and tighter space. In
the end, the water ran up to 32 meters (90 feet) above sea level, about
the height of an 8-story office building. 84
The force applied to the sea floor causes mountainous waves to
form by causing the water to rise up vertically.
