Help cliffs and such

[paskins]

how high would a cliff have to be to make it viable for jumping? would sand/water affect reliability in a major way?

I heard that 10 "storeys" was the minimum for land... tho for water it might be 25 "storeys".

Welcome to SaSu, hopefully conditions improve since this post.

The minimum lethal height depends a lot on your weight and the position that you fall in. How much do you weigh? Generally, you should be looking at a drop height of about 50 meters in order to make sure, but the higher, the better. Sand and water do affect reliability in major ways.

A hard, solid surface like concrete is by far the best thing to fall on. It doesn't absorb any of the force from your fall, so all of it bounces back into your body and causes deformations and ruptures within milliseconds.

Sand is a very bad surface to fall on, especially if it's dry sand. It will shift, compress and flow around your body to let it through. You'll still get injured, but it's unlikely that you die unless you fall from EXTREMELY high up (at least 100-200 meters, I'd reckon). Wet sand is a bit better, and acts more akin to weak low-quality concrete, but I still wouldn't risk it.

Water depends entirely on how fast you fall (again, your rate of acceleration is determined by your falling position and weight). Assuming average weight, anything below 10-15 meters is relatively safe, and the water surface will deform to let you through. 15-25 meters starts to be dangerous, and the water surface starts to feel hard and tough upon impact, but if you land feet-first, you'll be relatively safe; if you don't, you can expect injuries like rib damage and organ bruising. At anywhere above 30 meters, the water can't move fast enough to let you through, and it behaves like a solid surface during the impact. If you're going to land in water, make sure that you fall belly-to-earth or back-to-earth; this will maximize the amount of damage that is done to your body. An additional benefit of water is that even if the initial impact doesn't kill you, you're still going to drown afterwards, unless someone sees you and decides to fish you out.

I weigh around 130kg, from google the cliff is about 240m, but from looking at it in videos, i cant make out any parts that are especially steep to ensure a straight-down fall. would it be a bad idea to say the name of the cliff here?

other than cliffs there's not many tall buildings that are accessible that come to mind. if saying my area name is allowed then it would be nice to have some pointers
