Blasting is going on in Ball Eye Quarry though, which isn't that far from Clatterway. It may be that rather than the earthquake. Of course it could be entirely natural and just 'time to fall'. I'm not exactly sure what they use at Ball Eye, but at Hope Cement they're using AMFO as far as I know, as they need to shatter the rock as much as possible to reduce the amount of crushing at the plant. I know they've felt the blasts at Blue John Cavern recently, which is 2.6km away. Awkward one to explain to tourists when they obviously didn't hear the warning siren.
