Listen Current: Oklahoma Earthquakes
From Listen Current, 12/09/2015 -- Oklahoma has experienced more than 5,000 earthquakes this year. Some scientists tie these earthquakes to fracking, the extraction of oil and gas from deep within the earth. Fracking uses water to extract the oil and gas and is then injected into underground wells for storage. This can put pressure on faults and cause them to slip and trigger an earthquake. After inspections were ordered, state regulators shut down the water disposal wells, which slowed the earthquakes. But once the wells came back online the earthquakes started again. Listen to hear more about how oil is related to earthquakes in Oklahoma.
