Is there a fault line near Hawaii?
Hawaii is far removed from geological fault lines (which makes the Hawaiian volcanoes also something special), but the hot spot below the Hawaiian islands and the volcanic activity caused by it causes enough stress in the earth’s crust to make Hawaii a very active seismic region.
