Short-term and impending earthquake prediction are still a worldwide problem. At present, it is impossible to accurately predict the magnitude and time of an earthquake. Foreign seismologists generally believe that when plastic rocks or serpentinite in the lower crust are squeezed into cracks in the upper crust, it will cause earthquakes. These slippery serpentines are formed by the interaction of iron-and magnesium-rich minerals with water, producing hydrogen in the process. Once the layer breaks, hydrogen emerges through the cracks in the fault, resulting in a sharp increase in the concentration of hydrogen in the normal air.
