Typically, a tsunami is generated by an underwater earthquake, where one plate is subducted, and another is pushed upward, causing a large wave.
California is no stranger to tsunamis, as it faces risks from both local and distant tsunamis.
There is a lot of seemingly conflicting information about the potential and probability for tsunamis generated by a Cascadia earthquake. The report uses existing tsunami data to create an inundation model for San Francisco–basically, what size waves will reach the shores of the city.


Sensitivity study results show that the San Francisco Bay area is at greatest risk from a tsunami generated in the eastern portion of the Aleutian-Alaska-Cascadia Subduction Zone.
This report shows that maximum wave heights actually reaching the shores of San Francisco would be generally no greater than 3-4 meters. In recent years, California has produced inundation maps that show potential water levels in a tsunami event. There are many resources available online for preparing yourself in the event of a tsunami.


Waves generated by tsunami’s are obviously much more powerful and are shaped differently than normal, wind-generated waves [1]. The worst tsunami event in California occurred in 1964 as the result of a magnitude 9.2 Alaskan earthquake.
