APPLICATION OF HURST INDEX OF EARTHQUAKE FREQUENCY IN THE PREDICTION OF EARTHQUAKE

the Hurst index of earthquake frequency before 18 medium and strong earthquakes in north China is analysed.The characteristic of H value for the Hurst index of earthquake frequency before medium and strong earthquakes is summarised.The method has been used in earthquake prediction of Henan Province and its adjacent area, and the regulation for prediction is also established.After test with inner coincidence and prediction scoring, we find it is an effective method for medium term and short term prediction.
