Obsolete tsunami sirens are being replaced on the west coast of Vancouver Island to better alert people in Port Renfrew and the Pacheedaht First Nation in case of an emergency.

The BC Disaster Mitigation Program is providing $550,000 to install a new state-of-the-art warning system that will include voiceover capability and remote activation.

The province says that will expand the audible warning zone to include the Pacheedaht First Nation as well as Port Renfrew.

It says the system will have the potential to provide early warning prior to an earthquake actually occurring -- giving residents time to head to high ground.
