The Big Island of Hawaii is an active volcano, with some areas of the island considered to be at higher risk than others. The East side of the Big Island has ongoing activity in the Volcano National Park area.
Some areas of the island are considered to be "low-risk" with no active volcanic activity for hundreds of years, and none predicted in the indefinite future. Remember - no place on earth is guaranteed to be safe. Every area of the planet has its own risk factors including tornadoes, earthquakes, floods, tsunamis, hurricanes, etc.
You have to decide where you choose to live, and what natural risk factors you're willing to accept.
