| Abstract: | In this paper, one of the distribution-free tests — randomization test, is briefly described. It doesn’t need any distribution
assumption and its related parameter estimation and is applicable to random and nonrandom sample. Then it is used to the test
of migration of strong earthquakes on the Xianshuihe Fault Belt and “immunity” of large earthquakes in the large northern
reigon of China. The test results show that there is 98.7% confidence degree for the migration of strong earthqueks on the
Xianshuihe Fault Belt and “immunity” of earthqueks withM
S⩾8 toM
S⩾7 is significant in the large northern region of China. The obtained test results and the test method itself have certain
application in the practice.
