Coal mining takes place in the three mountainous regions at 40 distinct coal beds near Mesozoic basins. [15] Besides coal, resources such as slate, kyanite, sand, and gravel are mined, with an annual value over $2 billion as of 2006. [16] Virginia has a low risk of earthquakes, [17] especially in the
