Can people cause tsunamis?
It's possible. You would need a powerful machine, though.
Nobody's really gonna do that if its possible
If they could cause a landslide into the ocean, yes.
No, I don't think it's possible.
we would need to shift plate tectonics so explosives would need to be placed under the sea floor in the right places. thats my guess
Only if yo momma jumped into the ocean
Tsunamis are weather phenominon. If you think people can do that...
Can people cause rain storms or tornadoes? No, that's God's power, not ours.
