Unveiling the Enigma: Scientists Identify the Origin of Earth's Mysterious Tremors

New research has confirmed that fracking, including with liquid carbon dioxide, is responsible for previously unexplained small earthquakes or tremors. Fracking involves injecting fluids below the Earth's surface to extract oil and gas, and while liquid CO2 fracking can sequester carbon and benefit the environment, both CO2 and water-based fracking can lead to tremors, potentially causing larger damaging earthquakes. Monitoring and understanding these activities are crucial to track fluid movement and deformation of rocks, as well as to prevent migration towards unknown faults and triggering seismic activity.
