The earthquake happened 26 years before the U.S. had the capability to issue tsunami warnings, but Thomas Jaggar, the director of the Hawaiian Volcano Observatory, tried to warn the Hilo harbormaster about the possibility of a tsunami. His warning was not taken seriously and one fisherman was killed when the tsunami hit.[4]
