Oil Production Linked to Biggest California Earthquakes

“The largest—the 1933 Long Beach earthquake—was magnitude 6.4, killed 120 people and caused $50 million in damage (in 1933 dollars). In every case oil and gas companies had drilled the wells more than a thousand meters down, which was unusually deep for that time period.”

“Richard Allen, director of the Seismological Laboratory at the University of California, Berkeley, says “We need to start recognizing that there’s a growing body of evidence that oil and gas production activities can generate large-magnitude, damaging earthquakes. And that’s something we should all take very seriously.”
