Sometimes human activities can trigger an earthquake, causing a fault to move earlier than it naturally would. In 2017, some British scientists decided to catalogue these. They found that about half were due to extraction—of mining products, groundwater, or oil. Removal of material changes the stress, which can cause faults to move.
