Outside Lyudmila's fatally broken ribcage, there are several other details that may be indicators for a blast wave caused by a epicenter high in the air.
Of course these details can be explained by other causes.
First detail: two pair of missing eyes
In case Lyudmila and Semyon had been standing in the ravine while both had been hit by the blast wave, this blast wave had caused a high speed whirling of small particles, like sand/dust particles within the ravine. These particles may have penetrated the eyes of Semyon and Lyudmila.
Scientific literature on blast injuries describe blast wave victims, that suffered from eye injury caused by high speed particles/dust/sand penetrating the eye ball. This literature also state a warning that this eye injury may be visible one day later.
Remark: instructors in the workplace of my university of technology became very angry when students left a closing key in the mill and when students played with the air pressure hose.
Second detail: foam on the mouth of Yuri Dor.:
Some time after being hit by a blast wave, foam on the mouth may be an indicator of a blast lung, according to scientific literature.
Third detail: tent cut open from the inside
In case a blast wave had hit the tent, the tent cloth had been pressed upon these members during the compression. During the decompression, the tent cloth had been lifted. After the decompression and high winds, the tent cloth had fallen on the group members and there had been a 'white out' for a limited time. After a brief recovery, one or more group members had cut themselves free out of the tent cloth that had been lying upon them.
Fourth detail: Snapped skipole
The photos of the tent site show a possible snapped bamboo ski pole. The compression/decompression may have caused the snapping/cracking of bamboo. Bamboo sticks - thrown in fire - is still used as fire crackers.
Last personal remark:
In six parts, I have tried to arrange the last two days of the Dyatlov group - by arranging the details as found by the two search parties - in an order that make sense, follows the laws of physics, and reflects human behaviour.
In this study, two details are pivotal:
1. Lyudmila's broken ribcage
2. Except very probably Zinaida, all group members had been placed in their postures -as found by the two seach parties - after they had lost consciousness for the last time in the process of hypothermia (and Lyudmila fatal injuried). The raised arm of Yuri Kri is an indicator of being displaced while rigor mortis had already developed in the joints of his shoulder/elbow. This could only have happened within a very narrow timespan, because 24 hours later the bodies had been solidified/set in ice. Either there had been an external 'cleanup party' (no traces found by the first search party!), or two group members had been in the position to place the bodies of their deceased group members to be found by the search party: there had been only one place with an adequate insulation for surviving the cold night: the re-erected tent on one broken(?) ski pole.
