Siren network considered

The Hibiscus & Bays Local Board will be asked to provide “in principle support” for the development of an enhanced and expanded regional tsunami siren network at its meeting this week, on October 18.

The details of what this network could look like will be the subject of further reports. The local board has already considered Auckland Emergency Management Group’s draft Public Alerting Framework and the study by GNS Science on communities most at risk from tsunami (HM June 14) in workshops.

The GNS report notes that Orewa has the highest exposure to tsunami inundation in Auckland, with an estimated 6521 people exposed.

Silverdale Central rates seventh, with 1543 people and Stanmore Bay East ninth, with 1236 people exposed.

Auckland Emergency Management says that the next steps involve procurement and design of tsunami sirens and signs. Further information will be presented to local boards in due course.
