ON SEISMOLOGICAL INVESTIGATION. 167 



Earthquake of February 19, 1897. Oiigin, Japan (8h. 49m. Os. G.M.T.). 



This earthquake was not recorded at Shide, the clock of the recording 

 apparatus having stopped. It was recorded at other stations as follows : — 



H. M. s. 



Edinburgh 9 30 (maximum) 



Nicolaiew 8 52 



Ischia 8 55 30 



Potsdam 9 4 1 



The following are the times (J.IVLT.) at which the shock was noted in 

 Japan : — 



Miyako. — 5h. 49m., strong and sudden, clocks stopped. 



Yamagata. — 5h. 49m. 10s., strong and sudden, clocks stopped. 



Akita. — 5h. 49m. 30s., strong and sudden, clock stopped. 



Ishinomaki. — 5h. 49m. 30s., strong and sudden, clock stopped. 



Niigata. — 5h. 46m. 36s., strong, clocks stopped. 



Fukushinia. — 5h. 49m. 48s., strong, clocks stopped. 



Utsunomiya. — 5h. 50m. Os., strong, houses shaken. 



Mayibashi. — 5h. 47m. 56s., strong, clocks stopped. 



Tokio. — 5h. 49m. 37s., strong and slow, clocks stopped. 



Mito. — 5h. 50m., strong and slow, clocks stopped. 



Kofu. — 5h. 50m., strong and slow, clocks stopped. 



Choshi. — 5h. 51m. 24s., strong and long. 



Ifagoya. — 5h. 52m. 36s., strong, clocks stopped. 



Jfagano. — 5h. 50m. 5s., weak and slow. 



jK'gaya. — 5h. 48m., weak and slow. 



Aivomori. — 5h. 50m., weak and sudden, clocks stopped. 



Hakodate. — 5h. 59m. 48s., weak and sudden, stopped. 



Uwajima. — 5h. 52m. 45s., weak and slow. 



Yokosuka. — 5h. 49m. 57s., weak and long. 



Yokohama. — 5h. 51m. 20s., weak, clocks stopped. 



Hamannatsv,. — 5h. 7m., weak. 



Eikone. — 5h. 50m. 27s., weak and long. 



'Gifu. — 5h. 57m. 10s., weak. 



Kioto. — 5h. 51m. 4s., weak, with rumbling. 



Fushiki. — 5h. 50m. 45s., slight and slow. 



Nemuro. — 5h. 40m. 45s., slight and long. 



Kushiro. — 5h. 50m., 50s., slight, with rumbling noises. 



The greatest disturbance appears to have taken place at Sendai and 

 in N.E. Nippon, from which it is not unlikely that the origin of the 

 shock was near to that of June 15, 1896 (see Shock No. 1). This being 

 the case, the rate of travel on paths 9,749, 8,760, and 8,241 kms. to Ischia, 

 Potsdam, and Nicolaiew would respectively be 24, 9*7, and 45 kms. per 

 second ! The first and last of these computations we hope to be in a 

 position to correct in some future report. 



Examples of earthquakes which have sensibly shaken the whole of 

 North Japan caii be found the effects of which do not appear to have 

 reached Europe.
