    Abstract: The current situation of microseismic monitoring at home and abroad is not optimistic. The principles, data acquisition, data processing, and intepretation of many monitoring methods are far from the requirements of microseismic monitoring characteristics, and far from the level of analyzing specific microseismicity. We argue that the main technica... Show More
