The injuries is from tumbling around in the avalanche, a tent (if nailed down) will just be flattened.

How would one tumble in the avalanche while in the tent? Is the thought that the group heard the avalanche, came out, and got caught in it?

I should read the paper more carefully. I'm going off what I remember from Dead Mountain by Eichar.

The article says, perhaps that was a small & solid slab of packed snow that fell on the tent, broke some bones, and slid away.
