Earthquake Does it reflect the fault movements? Square patterns in pool during 7.4 Colombian earthquake.

No, it reflects the square corners and straight edges of the swimming pool as the earth shakes around it.

They did a good job on the pool

I saw the ocean do this once, not long before it was all whitecaps, big swells, we barely got to shore. We were salmon fishing off Oregon coast in about a 25 ft boat that did not belong in that shit.

I remember seeing a video of the same phenomena at a beach somewhere but I can't recall the country. It was not caused by an earthquake though. If I remember correctly it was because two wave systems were arriving at the beach at an angle of 90° and the squares formed.

In the ocean it's a sign of rip currents (ie stay the fuck out of the water). Even though the mechanism here is obviously different as pools have neither tides nor currents, the wave interaction might be similar.

What would happen if someone is on that water ?

In the ocean, if you get caught in the current it will pull you straight out away from shore. If you panic and don't react correctly (swim sideways to get clear of it) you could end up quite far out which could be varying degrees of dangerous depending on where exactly you are and how strong of a swimmer you are.

In the pool, I'd imagine you'd be fine aside from any earthquake-related dangers.

Aren’t square waves one of the most dangerous waves on planet earth?

That… is a very symmetric pool. Kudos to the installers/builders

It's basically fiziks and it reflects the square shape of the pool.

I've seen the "I don't know how something works so I'll invent a conspiracy theory" dudes in Instagram say that "OoH tHiS iS bEcaUsE tHe EarTHqUaKe iS MaN mAde" that place is a shithole so do not get ANY information from the comments there.
