would you rather die in a volcano or a tornado?

Dying inside a volcano is not biologically possible. You would have already been dead from incineration long before coming within meters of touching lava; let alone entering a volcano.
Now, if you were to say a 7.5 Earthquake and a mad-eye tornado, both will disrupt the nervous system pretty hard; from what I understand. I'm wondering if maybe in a tornado you'd less likely feel any horrid agony from injury. (I heard from rumor that the nervous system shuts off before a long-falling body is mere moments from hitting the ground, so that it can't remember the unbearable terror that exterminates the body when it does.) With an earthquake, there still is a chance that the body might survive to experience the grave injury from falling objects; a longer, horrifically painful death.
Tornado for me, I suppose.
