Hawaii’s earthquakes are driven by active volcanism, especially around Kīlauea and Mauna Loa on the Big Island. This page pulls real records for Hawaii: the largest earthquakes on record from USGS, how often the ground shakes nearby, tsunamis from the NOAA database, and volcanoes from the Smithsonian program.
