Council to discuss better tsunami alert system

San Diego City Council will consider the mayor's response to a grand jury report that recommends better advance warning in the case of a tsunami in San Diego. KPBS reporter Alison St John has more.

The grand jury report says San Diego doesn't have adequate maps showing which parts of the region would be inundated in a tsunami, and no community except Coronado has a system of warning sirens.

Jill Olin, head of Homeland Security at the city, says sirens aren't as helpful as you'd think.

Olin: "Because if you've got the siren, ok was that nuclear and I go underground or was it tsunami and I go above ground, it's not as easy as it used to be with our the air raid sirens and that was our threat and you all knew what to do."

Olin says inundation maps are costly to produce and in the event of a tsunami, the public doesn't need a map to show them where to head for higher ground. However she says the city has recently hired an evacuation planner with money from the Federal Homeland Security grant. Alison St John, KPBS News.
