In-situ stress measurement is an important approach to realize earthquake prediction – developing J.S. Lee’s scientific ideas on earthquake prediction

摘要

In 1960s, J.S. Lee (Si-Guang Li) pointed out that, tectonic stress and its variation have tight relationship with earthquake, and unraveling the stress variation process by in-situ stress measurement is key to realize earthquake prediction. On the basis of Dr. Lee’s speeches and my own experiences of the related practices, some significant ideas from Dr. Lee on the earthquake prediction were introduced. Today, his ideas on “safe island” and earthquake prediction still have theoretical and practical significances.
