oceanic trench
that parallels its arcuate coast. Nearing the
Solomons, the trench swings southeasterly, then down along the Vanuatu chain before turning east
and ending below Hunter Island. this trench system marks the
subduction of oceanic crust
-- the Solomon and Coral Seas -- moving north, northeast, and east under the volcanic islands formed by this
process. Tectonic complications in the form of two short oceanic spreading centers affect nearby volcanoes.
One extends from SE New Guinea eastward to Kavachi,

the Admiralty Islands at the north end of the region.

Kavachi, one of the most active
submarine volcanoes
in the SW Pacific, occupies an isolated position in the Solomon Islands far from major aircraft and
shipping lanes. Kavachi, sometimes referred to as Rejo te Kvachi ("Kavachi's oven"), is located
south of Vangunu Island only 30 kilometers north of the site of
subduction
of the Indo-Australian plate beneath the Pacific plate. The shallow submarine basaltic-to-andesitic
volcano has produced ephemeral islands up to 150 meters long at least eight times since its first recorded
eruption during 1939. The roughly conical volcano rises from water depths of 1.1 - 1.2 kilometers on the north
and greater depths to the south.
