Olivia Allen Price, host of Bay Curious, dives into the chaos sparked by a tsunami warning after a recent earthquake in Humboldt County. She discusses the real implications of a tsunami hitting the Bay Area, contrasting Hollywood portrayals with actual risks. Listeners share their fears and stories, highlighting community reactions and emergency preparations. Olivia emphasizes the importance of understanding tsunami hazards and proactive safety measures, urging residents to explore resources for readiness against natural disasters.
A recent tsunami warning highlighted the Bay Area's preparedness challenges and the importance of effective disaster response protocols during seismic events.
The podcast explains that tsunamis result from underwater earthquakes and emphasizes the need for residents to understand evacuation routes and inundation maps for safety.

Recent Earthquake and Tsunami Warnings
A significant earthquake off the Humboldt County coast triggered emergency alerts throughout the Bay Area, raising concerns about a potential tsunami. In West Berkeley, schools evacuated students as a precaution, while residents at the Emeryville Marina prepared their boats for possible flooding. Despite the initial tsunami warning leading to precautionary measures, it was lifted shortly after the earthquake, highlighting the importance of preparedness in such emergencies. This incident serves as a reminder of the region's vulnerability to seismic events and the need for effective disaster response protocols.
Understanding Tsunamis and Their Origins
The podcast explores the mechanics of how tsunamis are generated, emphasizing that real tsunamis are much smaller than those depicted in movies like 'San Andreas.' In reality, tsunamis result from underwater earthquakes that occur when tectonic plates shift, particularly in subduction zones. The Bay Area's fault lines are not conducive to large tsunamis, primarily because most of them are land-based and do not produce significant water displacement. Instead, tsunamis that have been recorded in the Bay generally originate from distant subduction zones, such as those near Japan or Alaska.
Potential Impact of a Large Tsunami
In the unlikely event of a significant tsunami reaching the Bay Area, the immediate effect would likely be flooding in low-lying coastal areas, such as Ocean Beach and Half Moon Bay. As the tsunami passes through the Golden Gate, complex wave interactions would occur, potentially causing significant damage to marinas and waterfront structures due to strong currents rather than height. While the probability of such an event is low, preparedness is essential, as residents could have hours of warning to evacuate if a substantial tsunami were generated. Understanding inundation maps can help residents plan for safety in the event of a tsunami emergency.
People across the Bay Area were rattled by a tsunami warning alert on Thursday morning, after a magnitude 7.0 earthquake hit the coast of Humboldt County. The warning triggered evacuation orders before it was eventually canceled at approximately 12:00 pm. But it begs the question: What would really happen if a tsunami hit the Bay Area? Back in 2017, our friends at Bay Curious set out to answer this question.
