Not All Waves Are Created Equal: The Tsunami Type-Down
Tsunamis aren't your average rogue wave caused by a grumpy Neptune. These monsters are triggered by dramatic events on the ocean floor, like earthquakes or undersea volcanic eruptions. Imagine a giant underwater earthquake shoving the whole water column upwards – that's the recipe for a tsunami.
Now, San Francisco is on the coast, but it's not exactly next door to a major earthquake zone. The city is more susceptible to distant tsunamis, which have travelled hundreds or even thousands of miles by the time they reach the Bay Area.
Tip: Keep your attention on the main thread.
The Great San Francisco Splash: Myth or Reality?
So, can a tsunami hit San Francisco? The answer is yes, but with a big ol' asterisk. The city has experienced minor tsunami ripples in the past, caused by distant earthquakes. The most notable one came all the way from Alaska in 1964, but it caused more surprise than damage.
The real whopper waves are much less likely. San Francisco Bay's geography actually helps to dampen the impact of distant tsunamis. Think of it like a wave hitting a beach towel – the energy gets spread out, reducing the wave height.
QuickTip: Skim the first line of each paragraph.
Here's the bottom line: A catastrophic tsunami hitting San Francisco is unlikely, but not impossible.
