If coal mining causes earthquakes, it would be a simple matter to study areas where massive coal mining was engaged to see if any earthquakes occurred due to the extensive mining. For instance, have there ever been any earthquakes in Wales? One coal mine proves nothing.
Gadzooks! I just googled earthquakes in Britain, and there’s actually been quite a few over the centuries. However, few deaths have been reported. I would think that with the massive coal mining that has gone on in Britain over the last two centuries, the whole island might have caved in according to the er scientist’s analysis.
