WebMost faults in the Earth’s crust don’t move for a long time. But in some cases, the rock on either side of a fault slowly deforms over time due to tectonic forces. Earthquakes are … WebThere are very few data on damage in the subsurface due to earthquakes. This fact itself attests to the lessened effect of earthquakes in the subsurface because mines exist in areas where strong earthquakes have done extensive surface damage. More damage is reported in shallow tunnels near the surface than in deep mines. ray white sutherland shire facebook
