While living in the yurt experienced 2-3 strong storms, at my site up to 120km/h I would estimate. I'm kind of a slow learner at first as I had to fix and fasten the yurt while the storm was underway as I often hoped the ropes I used were sufficient, and experienced they were not.
It's worth noticing, the storms affects the roof mostly, no impact to the wall as I noticed, me using 90° lattice angle and bamboo, with stretching the rain wall cover below the floor and use one rope on that height, almost on the ground, all around to fasten it (as seen on a photo above already). Some people put some small laths on the floor to fixate the lattice wall on the floor, or screw the door frame on the floor, both which I didn't do.
That's the bottom end of the windspeed of an F1 (weakest grade) tornado.
I have no doubt the architecture of choice of people's who lived in the steppe regions of Central Asia, a place where extreme winds are pretty common, would obviously need to be able to handle these winds but it still feels hard to believe that an amateur yurt builder could get one able to withstand a weak tornado on their first build...
The structure seems to be ideal for withstanding winds, the winds would go around the building as it's round rather than rectangular. Seems professionally built yurts commonly can withstand ~220km/h or more, so I don't think it would super farfetched that a amateur built one could withstand half of that.
Some of the poles are stuck into the ground just a bit, and then it's probably because the wall grates stick into the ground too, under the weight of the yurt. Here's an example:
For Hexayurts (https://www.appropedia.org/Hexayurt) one can create a rope halo that goes around the top of the roof, with a series of anchor ropes going down to the ground. Very effective at keeping foam structures well anchored at Burning Man, where the wind can be quite fierce.

So, what keeps the Yurt from planar movement? Is it anchored via stakes somehow?

Seems to be fastened somehow, but it's not specified how.

BTW, here's the process of making the whole yurt set:
