This page is still grounded in the JSON dataset, but this hazard does not yet have ZIP-specific scoring in the current risk CSV.
Tsunami and seiche hazards mainly affect Oakland's shoreline and other low-lying water-adjacent areas. Most events have been minor, but a stronger event could create fast-moving flood and evacuation problems.

If you spend time near the shoreline, the airport, port-connected areas, tidal flats, or other low-lying water edges, you should know your evacuation route and warning signals.
A distant or regional tsunami could push water into low shoreline areas, close transportation routes, and force fast evacuations. Larger events could disrupt wastewater plants, rail, and airport operations.
For most Oakland residents this is a lower-probability hazard, but for shoreline users and workers it can become an urgent evacuation and infrastructure problem.
Tsunami/Seiche Preparedness: 0/5 complete
Low riskThe LHMP ranks tsunami/seiche low because most recorded impacts are minor, but the shoreline exposure is still meaningful. It remains a moderate app priority because a larger event could affect thousands of people, critical facilities, and evacuation routes.
