5. A seiche (pronounced /se/ "saysh") is a standing wave in an enclosed or partially enclosed body of water.

6. Hilo Bay Seiche April 1st 1946 The tsunami that hit Hawaii in 1946 had a fifteen- minute interval between wave fronts. The natural resonant period of Hilo Bay is about thirty minutes. That meant that every second wave was in phase with the motion of Hilo Bay, creating a seiche in the bay. As a result, Hilo suffered worse damage than any other place in Hawaii, with the tsunami/seiche reaching a height of 26 feet along the Hilo Bayfront, killing 96 people in the city alone. Seiche waves may continue for several days after a tsunami.

13. Structures should either be placed at elevations above those likely to be adversely affected during a tsunami or seiche event or be designed to allow swift water to flow around, through, or underneath without causing collapse. Big Wave Project DEIR IV.H Hydrology & Water Quality Page IV.H-61

14. ABAG tsunami maps show that the project would place residential and commercial structures within a mapped tsunami zone.

15. Emergency Evacuation Would you want to be trapped with swirling water and debris all around you? Would you want to desperately try and escape a natural disaster with traffic from the office park choking your exit? How do special needs people get the necessary evacuation help needed?

16. Grand Jury Report The San Gregorio fault, just off the San Mateo County Coast, has the potential of causing a tsunami with essentially no warning time. The San Mateo County Office of Emergency Services (OES) advises that members of the public who are in low- lying areas immediately head for high ground when an earthquake occurs.
