Is it possible to cause a volcanic eruption by chucking objects or explosives?
I’m no geologist or scientist but I cannot imagine this to be possible. After all a volcanic erruption is something that happens naturally as and when the earth is ready, as if this was possible I’m sure that if terrorists wanted to cause damage by manually errupting a volcano I think their first target would be one of or all of the super volcanoes, one such as the one in Florida that is said to be able to destroy half the worlds population (if not all) whenit blows. Try looking up how a volcanic erruption is caused.
