The earthquake is short-term, and the earthquake prediction is still a worldwide problem. At present, accurate prediction of the magnitude and time of the earthquake is not yet possible. Foreign seismologists generally believe that plastic rocks or serpentine in the lower crust are squeezed into cracks in the upper crust. Earthquakes will occur at these times. These easily sliding serpentine rocks are generated by the action of minerals rich in iron and magnesium with water, and hydrogen is produced in the process. Once the layer breaks, hydrogen passes through the fractures of the fault Emerging, causing a sharp increase in the hydrogen concentration in normal air. What's the point of this text?
