There is no such division of microseismic geomechanics in the United States, but the characteristics of geology majors in each school are actually different, and there are also professors in various fields. However, it is very special that there are several schools whose professional rankings are in the forefront or the top few, which can give you some reference. 20 17 geophysical and seismological rankings are as follows: Berkeley, California is the first, Caltech is the second, Stanford is the third (the top three in California), MIT is the fourth, Columbia University is the fifth, Princeton is the sixth, Harvard is the seventh, and the University of Arizona is the eighth. Among these schools, the best one to apply for is the University of Arizona. Followed by the University of California, Berkeley. Others are too difficult, including the University of Arizona, which requires scientific research experience and papers. In addition, I read the articles about microseismic geomechanics in recent years, and found that the most famous university in this major is Leeds University in England, and many articles were written by professors of this university. I hope it helps you.

At the same time, I hope you can adopt my answer! thank you
