Hogwash!
Earthquakes are caused by shifting tectonic plates. Coal mines barely
scrape the surface.
Try Googling things before you make ignorant comments like that...

I know all about earthquakes...and they are NOT only caused by
shifting plates.
Fact is, collapsing mines do make the eart quake.

Probably true, but not the definition of a temblor. Ellen (Neal) is
correct.
