Earlier quoted context omitted.

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…

Fascinating story, thanks. How many astronomers have had a play and an opera written about them?

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

Interesting. I see no other video. I use brave so maybe it blocked all the ads and noise.

Firefox with AdBlocker Ultimate. Also saw no other videos, thankfully.

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!

By the discussions I've had with surveyors in my country (Sweden), any coordinate descriptions of properties are deferred to the physical markers in the ground (cairns for older property, metal stakes for newer ones). This would only be an issue in properties that have never been surveyed (and marked) at all. Straight borders might become crooked if they cross the crack though.

I am also in Sweden, and learned recently that a large part of my property seems to actually belong to the neighbour according to the online map! But there is a page in the relevant authority's website which clarifies that the online map can be 10s of meters off (in Swedish): https://www.lantmateriet.se/sv/kartor/vara-karttjanster/Visa...

There, it even explains some history and methodology for defining the borders. Mostly, they are defined by physical markers that hopefully the original surveryors left on the ground. I found a couple around my property (which is on hills so it's likely difficult to mark properly on a map from above) and it seems the borders are actually almost correct. As my fences have been up for over 20 years in the same location, I believe they also count now as de-facto borders now!

Area doesn't just disappear. I suppose that depending on what's on the land, your area might have a few more potatoes from your northern neighbors and fewer carrots you generously gifted to your southern neighbors.

You could alternatively just deal with your new jagged plot.

Worst case scenario, you're now the owner of the new Turkish Canyon.

I don’t think there’s a universally accepted solution but in California it would be up to the state to figure it out. It would be a great time to be a Real Estate lawyer after a quake there.

Land area does in a subduction zone.

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.
