THE GREAT ERUPTION OF SAKURA-.TIMA IN 1914. 173 



as compared with the vents of the northeast (the two^^ ventholes of 

 the Moyédashi fi]'e holes, in Text-fig, 37 [3 and 4]) which not only 

 sent down lava into the sea but also its submarine end rose to 

 become the islet of Inoko-jima (a Rock off Osé-zaki in Text-figs. 1 1 

 and 12). A group of islands comprising Shin-jima, Iwô-jima, and 

 Yébisu-jima represent, however, independent excentric submarine 

 vents (Text-figs. 11, 13[y, i, s]), which were undoubtedly connected 

 with the same lava macula of Sakura-jima, and sympathetically 

 burst open with the activity of the main conduit.

To speak more in detail, the southern lava issued from a 

 single deep and open oval bowl, called An-ei-San, on the apical 

 region of the south cone, running down in a narrow tongue to 

 the shore, and forming the point of Tatsu-zaki between Furusato 

 and Yuno-hama — a stretch of only a kilometer. The fresh craggy 

 stream of block lava can be easily recognized even from a dis- 

 tance. See Geologic Map. 



The northeast area, the Komen"^ lava-field, is ten times 

 larger than the preceding. The lava welled out from the east and

 lava-field, marked in Geologic Map.
