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.

PSA: it's easy to miss on the first watch because the big action happens in the background behind the gate.

Thanks, first watch all I saw was the driveway crack appear. Second pass could be mistaken for a parallax effect as the entire background shifts forward!

It does but it's just one of many factors that make maps diverge from the ground truth:

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?

Isn't this news several months old?

A previous discussion of the M7.7 quake in Burma/Myanmar from March 28, 2025 was provided by Sean Wilsey. He explained the earthquake and context and discussed the CCTV footage around 6:30 https://youtu.be/CfKFK4-HNmk

So, I recommend seeing it in 3 passes. 1st pass, see the right 1/3rd area of the video. It shows the 2 sides moving. Then see the middle 1/3rd area of the video. It shows both the movement and the rupture in the ground. Then see the left 1/3rd area of the video. It shows the rupture on the ground clearly.
