Answer 1

Answer:

The most common cause is extracting material from the subsurface—more than 50% of anthropogenic seismic events are attributed to mining or extraction of groundwater, oil, and gas. Removing the weight of overlying materials, which normally clamp faults shut, enables faults under stress to move more easily

Explanation:

hope this answers help u
