Hawaii has what the state calls the world’s largest integrated outdoor all-hazard public warning system, with about 400 sirens linked across the chain of islands. It’s supposed to be used to notify locals of natural disasters and other threats. But Hawaii Emergency Management Agency spokesperson Adam Weintraub told the Associated Press on Thursday that the departmental records do not show that the sirens on Maui were activated. Emergency alerts were instead sent to cellphones and broadcast on TV and radio, Weintraub said.
