And unlike other tsunamis where the flooding comes in and then goes away, Tina said the combination of the land drop and the waves is going to mean a much more permanent change to the landscape.
Yeah.
And the other thing that's important to know, Emily, is that this might not just affect the upper half of the West Coast.
It could also trigger another earthquake further south, the California Big One.
So just south of the Cascadia Fault is this other tectonic plate boundary called the San Andreas Fault.
And that one's responsible for a lot of earthquakes in California.
Remember Chris Goldfinger?
He's the paleoseismologist we heard from earlier.
Absolutely.
So in 1999, through a clerical error, he and his research team ended up sailing too far south and taking a sample of the San Andreas Fault.
And as they were comparing these samples, one from the Cascadia Fault and one from the San Andreas Fault,
they realized that all the events that these cores recorded were happening super close together, just time-wise, which is super weird, right?
So they took way more samples, they got way more data, and they realized that the Cascadia and the San Andreas were what geologists call seismically linked.
They have the potential to trigger earthquakes in one another.
We are not.
There's good news.
Because in the past few decades, scientists have developed the technology to create an earthquake early warning system.
Diego told me we have thousands of these little sensors located all throughout Washington and Oregon and California.
And they're all just listening to the earth, waiting to hear these tiny, tiny vibrations.
This entire early warning system can be activated in 15 to 20 seconds, totally automated without any human action.
