Why did Krakatoa explode?
This eruption was caused by high pressure buildup in the two underlying tectonic plates. The resulting break allowed for water to enter the volcano and mix into the magma cavity. This along with the extremely heated steam resulted in extremely intense pressure and an almost complete destruction of the island.

Yellowstone supervolcano
The Yellowstone supervolcano is a natural disaster that we cannot prepare for, it would bring the world to its knees and destroy life as we know it.

Could a nuke set off Yellowstone?
Some conspiracy theorists have claimed a Yellowstone eruption could be triggered by a nuclear bomb, but is this the case? The short answer, according to the United States Geological Survey (USGS), is a resounding no.
How overdue is Yellowstone?
Yellowstone is not overdue for an eruption. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. Even so, the math doesn’t work out for the volcano to be “overdue” for an eruption.
How bad would it be if Yellowstone erupted?
If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering crops, and shutting down power plants. It’d be a huge disaster.
What happens if you drop a nuclear bomb in a volcano?
The explosion of the bomb mixed with the build-up of pressure inside a volcano could amplify the eruption. The force would release even more ash and lava, spreading it even further than it would’ve gone with the volcano’s own power. And that’s if we managed to hit the target.
What are the 3 super volcanoes in North America?
