Banua Wuhu is a submarine volcano in the Sangihe Islands, Indonesia, 45 km south of Awu. The volcano rises more than 400 m from the sea floor and almost reaches the surface, forming a shallow shoal at 5 m depth. Banua Wuhu, during some of its eruptions, has created temporary islands, which were eroded subsequently by wave action. Adjacent Mahengetang island belongs to the same volcanic edifice. Separate vents are found to the northeast (Kahakitang) and north (Kalama) of Banua Wuhu.
Igneous or magmatic rocks: The most primitive rock type forms when magma (molten rock) solidifies - either inside the earth (plutonic rocks) or during volcanic eruptions (volcanic rocks). A short overview.
