It sure would suck to lose half your property to the earth suddenly saying screw you.

You could lose all your property, without compensation too, if your unlucky enough to have a big enough meteorite crash into it.

Or be native

Or lose a war, or bet your property or not pay taxes or eminent domain… but I guess nomads never had a immovable property claim.

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

It's tracked by some national agencies, for example NZ has a deformation model. This link has a summary & links to some lectures about the deformation model: https://www.linz.govt.nz/guidance/geodetic-system/coordinate...

Metres of movement would definitely be significant for a lot of mapping use cases. This is why the time component of any coordinate measurement is important, both due to earthquakes as well as plain old plate motion.

The natives lost something, to be sure, but I'm not sure it was property. Property is created when you kick everyone else out. I assume that's the rationale behind "property is theft," it used to be everybody's and now it's yours.

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's always been active. The Sagaing fault is a plate boundary. You're seeing the "side" of the Indian subcontinent slamming northward into the Eurasian plate.

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 about waiting over a decade and be getting a drink when it happens? Then waiting another decade and a technical problem preventing it from having been recorded. https://en.wikipedia.org/wiki/Pitch_drop_experiment#Universi...

also reminds me of:

in 1663 Scottish mathematician James Gregory figured out that you could calculate the distance between the Earth and the Sun by making measurements during the transit of Mercury or Venus across the Sun. You get much more accurate results with Venus, but the next transit of Venus wasn't predicted to be until 1761 and 1769.

In 1760 French mathematician Guillaume Le Gentil sailed from France to India to make observations of the transit, but due to weather and delays, he was still on the ship when summer 1761 arrived and he missed his chance to make his measurements. So he stayed in India for another 8 years. And then on the day of the 1769 transit, it was cloudy and he missed it again. So he went back to France where he found out he had long ago been declared dead, his possessions had been seized and his wife had married somebody else.
