Anybody know how property lines get reconciled after a fault slip like this?

I'm amazed to learn that we hadn't had video like this before, but it had to come about sometime!

Although the pole mentioned in the video is interesting, for me the more prominent visual signal of the motion is another pole right near the center of the view. It starts out visible within the frame of the arch, near its right side. When the quake hits, this pole moves so far to the right that it's almost totally obscured behind the wall of the arch, and it can be seen swaying back and forth.

Also, there is a pylon on the far right of the scene that seems to partially collapse.

It's cool that we have this video, but sobering to remember that thousands of people died in this quake.

Truly groundbreaking stuff.

This footage is incredible and invaluable for science. It really puts into perspective how much energy is released during an earthquake.

I'm getting older and pretty jaded, but this is genuinely amazing to see. Not only did an earthquake get captured, entire chunks of the earth moved both horizontally and vertically, measureable off of that video. I still get dumbfounded at the amount of energy involved in things like this, and how much potential is stored up in other faults getting ready to pop--and this was "just" a 7.7! Super interesting to see! We humans are but ants to this planet's heel, ready to be stomped upon.

incredible footage.

just mind bolggling to consider the energy involved here.
