Aardbeving 8.0 in Alaska

There are a couple of factors here. First, the Aleutians are very sparsely populated. The nearby towns that received heavy shaking in places like Perryville only have 100 or so people living in them. So it’s fairly sparsely populated.

But maybe more importantly is the depth of the earthquake, how deep it is in the earth. This earthquake occurred at a depth of about 32 kilometers, which is a good deal down in the earth, meaning that even if you were standing directly on top of where the earthquake was happening, you’re still 30 kilometers away from it.

Contrast that with something like Southern California where you can have very significant human impacts from significantly smaller events, because those faults rupture the surface. So, if you’re on top of where the epicenter is in California, you are zero kilometers away from where the earthquake is shaking. And that translates into much more potential for damage, much higher amounts of shaking.

	De aardbeving was heel diep, vandaar dat de schade beperkt is. Naast de magnitude, is de diepte ook een zeer relevante parameter bij een aardbeving. quote: There are a couple of factors here.
