Sector 2. The Line Islands, the Cook Islands, the Samoa Islands, and the Tonga Islands

tained over the volcano in 1943, but due to volcanic activity that resumed in 1999, less water may now exist.

2.51 Hunga Ha’apai (20°33'S., 175°25'W.) and Hunga

Tonga are two islands which lie about 31 miles N of the W extremity of Tongatapu.

2.51

Hunga Ha’apai rises to a height of 122m in its N part and

104m in the S. A ridge runs the entire length of the island, falling in high cliffs to the sea on the E side.

2.51

Hunga Tonga, about 1 mile NE of Hunga Ha’apai, has steep

cliffs; above the cliffs the ground rises to a wooded ridge that runs the length of the island.

A reef that breaks lies 2 miles SE of Hunga Ha’apai. In this vicinity a submarine volcano was reported.

2.51

Tides—Currents.—When navigating in this part of the group, vessels should make allowance for the strong W current. Fonua’ou (20°19'S., 175°25'W.) is of volcanic origin and at

2.51 2.51

times smoke has been seen rising from it. The island has changed shape many times and has at times disappeared. Volcanic activity has been reported in 1993.

2.51

Shoals are reported to lie 33 miles W of Fonua’ou.

2.51

The islands in the S part of the Nomuka Group lie 38 miles

NNE of the light on Malinoa. The group lies on an extensive bank, which has charted depths of 3.7 to 174m and many dry- ing rocks.

2.51

Kelefesia (20°31'S., 174°44'W.), the farthest S of the group,

is 37m high and wooded. Foul ground extends 4 miles SE of the island, and the rock 5 miles farther SE is marked by heavy breakers. There are other dangers E and NE which may best be seen on the chart.

Kefikana Rock, 4m high, white and conspicuous when the sun is shining on it, lies 3 miles WNW of Kelefesia.

2.51 2.51

Tonumea, an island 42m high and densely wooded, lies on a

reef 2.5 miles NNW of Kelefesia. The sea breaks on some foul ground which lies 0.8 mile NNW of the island.

2.52 Nomuka Island (20°15'S., 174°48'W.), about 11

miles NNW of Tonumea, is the principal island of the group. It is triangular in shape, with each side about 2 miles in extent; it encloses a saltwater lagoon. West of the lagoon there is an ele- vated ridge with a peak, 51m high, at the N end and a peak, 49m high, at the S end.

2.52

A fringing reef encircles the island and extends 0.3 mile off-

shore in places, but there are breaks in it where boats can approach.

2.52

Nomuka Iki, about 1 mile S of Nomuka, is separated from it

by a channel that has a least navigable width of 0.3 mile. The island rises to a height of 45m in the S part. The island is surrounded by a coral reef which extends 1.3 miles ESE from the S extremity, forming a dangerous point. There are reefs and shallows off the S and W sides of the island which break, but they have not been completely examined.

2.52

Muifuiva, a small islet, lies 0.5 mile NW of the N extremity

of Nomuka Iki. Lua Vaila, with a depth of 3.7m, lies in the middle of the channel 0.8 mile E of Muifuiva. A light is shown from the islet.

2.52

Nomuka Harbor lies between Nomuka on the N and Nomu-

ka Iki on the S; it is open NW, but is protected in other direc- tions by these two islands and adjoining reefs.

Pub. 126

2.55 Hakaufisi (20°09'S., 174°55'W.) is a reef lying about 7.5 miles NW of Nomuka; it is steep-to, dries in places, and the

2.53 Mango Island (20°20'S., 174°43'W.), an island 5

miles SE of Nomuka, is fringed by a reef which extends 0.8 mile SE. There is a wooded hill at its NW and SE ends, each about 43m high. A village with a church is situated on the N coast of the island. Anchorage for small vessels may be taken, in 22m, sand and coral, with the tangents of Mango bearing 126° and 196°.

Mango Iki, about 1 mile W of Mango, is 21m high to the tops of the trees, and is fringed by a reef which breaks. The passage between Mango Iki and Mango is bad, es- pecially during S winds.

2.53 2.53 2.53

Nukufaiau (20°18'S., 174°42'W.), about 2 miles NNE of

Mango, is encompassed by a reef which extends 0.2 mile offshore. A coral patch, with a depth of 6.4m, lies 2 miles WNW of the islet, and a patch, with a depth of 5.5m, lies 0.8 mile NNE of the islet.

2.53

Luafitu (20°20'S., 174°38'W.), a reef that covers 3.7m, is

located 4.5 miles ESE of Mango. Rocks and shoal water are charted ENE and ESE of this danger.

Nukutula (20°15'S., 174°41'W.) is a wooded sand cay, 5.5m high, standing on a reef 2.5 miles N of Nukufaiau.

2.53 2.53

Fonoifua, an island about 3.5 miles ESE of Nukutula, is 28m

high to the top of the trees on the S side, and rises to a cliff 20m high on the N side.

2.53

Tano’a, an islet about 0.8 mile S of Fonoifua, has a good

boat harbor in the reef N of it. 2.54 The Otu Tolu Group is composed of four islands

which stand on the same sunken reef about 15 miles ESE of Nomuka. They are low, wooded, and even-topped islands. Fetokopunga (20°18'S., 174°32'W.), the farthest N of the

2.54

group, lies 5 miles ESE of Fonoifua; it is 17m high and has no distinguishing feature. Telekivavau (20°19'S., 174°31'W.), 0.8 mile farther SSE, is 22m high. Telekiha’apai (20°21'S., 174°31'W.)(Lalona), the next islet, about 1.5 miles farther S, is 20m high, and Telekitinga (20°24'S., 174°32'W.), 2.3 miles farther S, is 16m high.

2.54

Tides—Currents.—The currents, especially in the vicinity

of the reefs, are uncertain in strength and are variable in direction. After strong E winds they set strongly to the W causing rips and blind rollers in places.

2.54

Caution.—The area enclosed between the reefs S of Otu

Tolu, Nomuka, and the islands to the S, is thickly studded with reefs and shoals, and it is unsuitable for navigation except under favorable conditions of light. The reefs are steep-to and not easily seen, even from the masthead. There are passages that can be used, but great caution should be exercised. A shoal has been reported to lie about 27 miles E of Tele- kitinga in about position 20°22'S, 174°03'W.

2.54 2.54 2.52

Anchorage.—Anchorage may be taken, in 24m, coral sand,

with the NW extremity of Nomuka Iki bearing 244°, 0.4 mile distant.

2.52

In the NW approach to the anchorage there are depths of

7.3m, 9.1m, and 8.2m, located 0.6 mile NE, 0.4 mile NNW, and 0.5 mile NNW, respectively, from the light on Muifuiva.
