In this picture you
can see the results of the effects of the forces contained in the tsunami
of 1918. This wooden house was torn from it's support columns and carried
out to the sea. Like in this example, the 1918 tsunami cause much damage
and loss of lives.
Approximately 45 people lost
their lives because of the tsunami of 1918 in Puerto Rico. This tsunami
was caused by an earthquake of a magnitude of 7.5. Most structures at the
time were poorly constructed and did not survive the attack of the tsunami.
Also their location close to the sea or in flood able areas made them vulnerable.
This picture is also from
the 1918 tsunami of Puerto Rico. Probably shot at the Mayagüez city
bay, it shows how the tsunami dragged a house out to sea. Also note the
tree that was unrooted and pulled to the bay. The tsunamis can will cause
destruction when they arrive as well as when they retreat.
In 1997 Professor Aurelio
Mercado, generated a simulation that demonstrated a possible scenario of
the 1918 Puerto Rico Tsunami. The results of this simulation were compared
to official reports and witness accounts. This confirmed the accuracy of
the simulation because the simulation concurred almost exactly to the what
really occurred in 1918.
