You said this was caused by an undersea volcano, so i really did not expect it to quit happening over there.Sorry.
Nope, it's not being caused by an undersea volcano, but we live right next to an extinct one, and heaps of the shocks are centred in the volcano crater. Nothing to worry about apparently - although we do have some new hot pools that didn't exist before.
But the shocks we are having are plain old tectonic plate action. That's what we get for living on the pacific rim of fire... Pacific Ring of Fire - Wikipedia, the free encyclopedia
