Great example of how canyons are formed over time. Imagine that going for hundreds of thousands of years on end,... you’d end up with some big canyons. Especially if it’s a softer layer.
Fascinating to read about this series of flood events at Awatarariki Fanhead in NZ, beginning with the May 2005 event, the repercussions and the council decision to repurchase houses due to insurmountable natural disaster risks. And then to look at Google Maps for Matata and see the changes to the land-use evident (many vacant resumed lot numbers) and on StreetView the one stand-out land-owner in 2021 with signs up "Whakatane Council hands off our homes". There are always deniers!
Oh my God, look at the way those giant boulders are tossed around like small pebbles... Imagine anyone or any animal being caught in that flow, they would be ground to a pulp...

I am still wondering, where is that water all the time. How it is possible, that will come so big wave at one time? I will expect, that it will gradually increase the intensity of flow, but I could not understand, what exactly "holds" that water and release it in so big wave at one moment.
When it's dry for a while small debris go where the water flows when it rains (I'm talking smaller than a river, imagine the little water flow that goes in a river). And when it finally rains the water will take it's usual course down the mountain, but if it's sudden and a lot of precipitation it will take those small debris with itself at once, but the water will be slowed down by them as if they were a dam. Then when more water comes and adds pressure it will go down hill again. Little by little it takes bigger debris, which need more water to be pushed down the mountain. After a while, if the conditions are right, what you see in the video is the result. You can try it on a small scale for yourself if you want. Find a dry dirt surface that is almost flat an pour a bottle of water in one spot, it should be a thick little stream that is pushing like a small dam.

@@thatcanadianguy9875 i was joking with that first comment. wasnt expecting to be taking seriously like this.. but damn that landslide must have been real hell to the ppl of that town :( i just can't imagine being in their place for a second
Holy shit that was scary! I don’t think it was very smart standing there above as it rushed down but hey, u gotta get the perfect angle for people to see the magnitude of it! That thing could’ve easily tossed a couple of them smaller 60-100lbs rocks up in the air and it’s by by camera man! But I did enjoy it though!
@@ButterBallTheOpossum I have not seen this bridge but it's not hard to see our human sense of scale falling flat on it's face when confronted with such an incredible sight!!
