Many people living in the Hawaiian Islands are accustomed to feeling occasional earthquakes since the State of Hawaii is one of the most seismically active locations in the United States. Unlike some other earthquake-prone places in the U.S., for example California, where the earthquakes are related to tectonic plates sliding past each other, our earthquakes are related to volcanoes.
