2 people died. From what I understand subduction zone earthquakes can be terrible, but it depends on the depth in the ocean at which they occur. If they are the right distance from shore and depth, devastating. But, further out and deep enough, they can often result in no tsunami. Does anyone know if that's supported by evidence?
I also keep seeing the author's quote about a 1 in 3 chance within 50 years that the big one hits. But in other places I've seen it say 5%. I'm a little confused by that number and what's correct.
It's scary either way. But, it does seem like the biggest death tolls occur where massive populations are spread near the coast, like in Indonesia.
- geoka9 7y agoThe scale is logarithmic (9.0 is ~32 times stronger than 8.0 in terms of energy release).
- Gibbon1 7y agoIn California is because our earthquakes come from strike/slip faults the largest earthquakes we can expect are around 8.0 like the 1906 earthquake. The Pacific Northwest has megathrust earthquakes that can reach 9.0 similar to the 2011 Tōhoku earthquake. That terrifies me because California isn't really prepared for what we're due. And the PNW is less prepared than California.
