As tsunamis go, the tsunami that followed the earthquake in Puerto Rico on October 18, 1918, wasn’t as fierce or as deadly as the one that recently occurred in the Indian Ocean. Nor was it as high as the one that hit Scotch Cap Lighthouse on Unimak Island Alaska on April 1,1946, which demolished the lighthouse and killed the five crewmembers. That same tsunami hit the Hawaiian Islands five hours later, wreaking much destruction and taking many lives, along with at least one lighthouse, Laupahoehoe Point. Even if the Puerto Rican tsunami on October 11, 1918, was not as large, it was no small thing to the people of the west coast of Puerto Rico. More than 150 people lost their lives that day. Many more were injured or lost their homes and businesses.
