HILO » Hawaii County is continuing to inspect its sirens after four tsunami sirens failed to pass the monthly test.

The Hawaii Tribune-Herald reported Tuesday that, according to Hawaii County Civil Defense, warning sirens in Keaukaha, Punaluu, Naalehu and Ainaloa didn’t pass the test Monday.

An administrative officer in Hilo, John Drummond, said there are many factors that can cause the sirens to malfunction.

He said officials pay weekly visits to sirens that fail, to try to determine a cause.

In 2013, the state began a $25.6 million siren modernization program to improve the reliability of the system. Shelley Kunishige with the state Emergency Management Agency said the first phase of the program has been completed recently, and now there are 74 active sirens in Hawaii County.
