EARTHQUAKE OF CENTRAL JAPAN, 1891. 399 



geological stnicfiire of the region traversed by this great fault i.s not 

 so well known as that of Lago di Croco in tlie Eastern Alps, still I 

 tliink, as has been already pointed out, that I ani justified in 

 supposing the existence of a number of shifted lines of dislocation, 

 stretching from north-west to south-east across the North of Mino. 

 TJie event of Ocfohrr, 1891, seems to me to have Jieeu a reneived movement 

 upon one of tliese jrrexistinij tissiives — tlie Neo valJeij line of fault, hi/ 

 which the entire region lijin(j to tlie riißit of it not onJij moved actiialJi/ 

 downwards hut was also sliifteil horizontallij towards tlte nortli-west for 

 from one to two metres aJontj tlie jdane of dishmition. Tliis vertical 

 movement and hovizontaJ shiftinij se<nn to me to have heen the .^ole cause 

 of tlie late catastroplte.
