C. Davison — Great Japanese Earthquake, 1891, 



The last line of the table shows that in every region but one 

 (namely A) the frequency of shocks after the Mino-Ovvari earth- 

 quake is greater than it was before. In two other regions, B and E, 

 the shocks during the succeeding fourteen months were relatively 

 twice and one and a half times as numerous as during the preceding 



seven years ; but the change is perhaps too slight to have much 

 significance. It is greatest of all in the region C, but this is chiefly 

 due to the large numbei-s of shocks which occurred during the 

 months of January and September, 1892 ; and it is uncertain how 

 far these were connected with the Mino-Owari earthquake.
