THE BIG ISLAND (Ben Caxton) — A recent test has discovered that an alarming one out of every ten tsunami warning sirens on the Big Island is broken. That according to Hawaii County Civil Defense officials after a test of the system was conducted on October 1st and nine of the ninety-two sirens islandwide did not work. The sirens warn people to move to high ground when an earthquake somewhere in the Pacific is believed to have generated an approaching tsunami. Tsunami alerts are also issued via cellphone, but officials say not all areas have reliable service and not all residents have signed up for the notifications. The county says that while their workers normally perform minor maintenance on the warning sirens like replacing batteries, it is the state Emergency Management Agency that is responsible for repairs and maintenance of the system.
