This part of Indiana I live in is pretty flat. Dull, right? So I figure, why not have a volcano? Now... I get my magic drill machine that can drill as deep as I want it to drill.
If I drill a deep enough hole, say through the crust of the Earth, will it turn into a volcano?
This region is thought to have been the site of extremely powerful volcanic activity in the past, so powerful that it caused mile-deep lava over an area as large as the state of California.
By Richards’ estimate, the asteroid impact must have generated the equivalent of a magnitude 9 or larger earthquake everywhere on Earth
Besides the earthquake, there was also a literal rain of fire across the planet, like a blast furnace, that likely killed everything that wasn't underground or underwater.
