The Possible Explanation for Secondary Microseisms Seasonal and Annual Variations
Annual drift is typical for microseisms. We propose a model based on thermoelastic wave generation that explains the highest microseisms during winter using higher stress level at the same time. If we remove the average influence of the back¬ground stress from the microseisms, we obtain the residual...
