THE ERUPTION OF IUXDA1-SA.V. 



169 



Earthquakes. 



Earthquake occurred before 

 the eruption, continuing for 

 about 20 seconds. It felt as 

 if something had fallen in the 

 next room. In general char- 

 acter it differed from the 

 shocks usually felt. 



Feeble shocks at about 8 

 a.m. on the 14th, and at about 

 4 p.m. on the 15th. 



Meteorological Conditions. 



Miscellaneous Notes. 



Very fine ; gentle N.W. 

 breeze, 85° F.; it was a little 

 stronger after the eruption. 



Very thick mist in the 

 morning, but gradually began 

 to clear away from about 8 

 a.m. It was quite fine at 

 noon. Thermometer 75° F., 

 at G a.m., 90° F. at 12 a.m. 

 About 8 a.m. W. wind pre- 

 vailed but afterwards turned 

 to S. At 11 a.m. it became 

 S.E. 



Very fine and calm early 

 in the morning. At about 9 

 a.m. a black cloud appeared 

 on the west, and became dark, 

 but it cleared again in the 

 evening. Therm. 85 D F. 



Very fine ; temp. 95° F. at 

 noon ; a gentle north wind. 



A dark coloured cloud seen in the 

 N.W., gradually spreading as it ascen- 

 ded. At about 10 h. 10 min. a.m. that 

 part of the heavens became so thickly 

 covered with misty cloud that we could 

 not see the mountain for 20 min. 



The thick smoke rising from Bandai- 

 san, which was generally regarded as 

 cloud, looked black and somewhat red- 

 dish. During sun-set sparkling rays of 

 red light were emitted from the cloud. 



In the direction of Bandai, cloud 

 of an elliptical form was seen.
