CCTV footage captures video of an earthquake fault in motion (smithsonianmag.com)

Isn't this news several months old?

Terrifying. I program automated vibration analysis for blasting, and a very powerful explosive blast will feature particle velocities (the direct corollary for power) in the single-digit in/s range (~0.02-0.13 m/s) . This peak particle velocity is 20-150x higher than the peaks we see from the most powerful blasts we measure, if they're at all qualitatively comparable.

And of course, the earthquake energy source is many magnitudes larger and much, much further away, deep in the crust, with the wavefront already having passed through miles of solid rock. We measure blasts from at most a few hundred meters away.

I know nothing so help me here. Why is this so rare? Aren't earthquakes, cameras, and monitoring of them pretty common?

Silly question but how does this affect mapping software? Or is the movement insignificant that it doesn’t matter

So many autoplaying videos on the page, and none of them are the video that the article is about.

4.x l to 5.x earthquakes are still happening a few times a week and the area couldn't recover from disaster. last week, one 4 stories building next to my friend house collapsed,near Mandalay.

Does that mean Myanmar is now an active zone?

It is remarkable how widespread of CCTV has helped in that field. Imagine being a scientist and never actually experience or see the earthquake you are into researching. That be like going to place where they are common and then sit a year or so and anticipating. Is it coming? Should be any time soon? Then when it happens you are in the toilet and have seen nothing apart from painting falling off the wall.

How does property/real estate ownership work in this case? Seeing the land shift so clearly by several feet makes me wonder.

What was on your property is now on my property!

in a sense it's mind blowing that we had images of stars being born, black holes, cells dividing etc before earthquake faults in motion. Like how the process of how they happen have only been inferred until now

The entire camera clearly dips and then rises during the fault slide. It's not the fault moving in a curved path, it's the camera dipping and rising. You can clearly see that just by placing your finger or mouse cursor on any feature in the video.

Makes me wonder how much energy the movement "released". Crazy.

Incredible
