LOCATION AND TOPOGRAPHY
The terrain around Suruga Bay is generally rugged and mountainous. The dominant topographic feature in the area is Fujiyama (12,395 ft), the highest mountain in Japan. This extinct volcano rises from the northern shore of the bay to its peak, 12 n mi away. Along the eastern and western coasts, the mountains rise abruptly to heights in excess of 4000 ft and 6000 ft, respectively.
These ridges lie generally in a north-south orientation with a "saddle" between them and Fujiyama. Figure V-2 (Yokosuka section) shows the topographic features of this region.
The Numazu Operating Area takes its name from the city of Numazu, which is located at 35°05'N, 138°52'E at the northwestern side of the Izu Peninsula on the northeast shore of Suruga Bay. The harbors of Shimizu and Tagonoura are also located, respectively, on the western and northern shore of Suruga Bay. Figure V-l9 locates some pertinent features. Suruga Bay penetrates the southern coast of Honshu in a north-northeasterly direction for a distance of approximately 35 n mi. Numerous ships of various sizes transit the bay enroute to the harbors mentioned.
Suruga Bay itself is characterized by extreme depths. At its entrance, the depth is in excess of 2500 m. An exception is in the south central region of the bay where the bottom rises up to within 30 m of the surface. Along the northern shore the bottom drops off to over 200 m within a mile of the coast.
