Those killed in Pompeii by volcanic eruptions were killed by tornadoes of heat ravaged the city after the initial wave of pumice and debris that fell, and instantly killed everyone in its path. This natural phenomenon is called pyroclastic surge. This is where fetal positions come into play. Instead of being indicative of a slow and prolonged death, the fetal positions were due to the fact that the muscles of the body contracted instantaneously due to extreme dehydration. They are not in fetal positions. They are in what is called an extreme cadaverous spasm. And, in addition to their postures, the cracking patterns in the skeletons of the bodies serve as testimony to the theory of their disappearance. And on the other hand To create the preserved bodies in Pompeii, Guiseppe Fiorelli and his team poured plaster of Paris into the soft cavities of the ash, which were about 30 feet below the surface. These cavities were actually the contours of the decomposed bodies and retained their forms despite the fact that the soft tissues decomposed over time. When the plaster was poured into the ash, it filled the spaces previously occupied by the soft tissue.
A common mistake is that the plaster bodies are empty. However, the cavities left by the bodies were not shells in the ash waiting for the plaster. In fact, they were soft spots that still retained the bones of the corpses. When the plaster filled the soft ashes, the bones were enclosed. Mount Vesuvius erupted and erased Pompeii in 79 AD.
