09/1968 (CSLP 33-68) Eruption on 6 September from submarine volcano

Card 0047 (14 September 1968) Submarine volcano near Mahengetan considered active and dangerous

The following was received in response to a query about the reported volcanic activity. "There are four volcanoes in the area: Awu in Sangir Island erupted August 1966, Karangeta at Siau Island, Ruang at Tagulandang Island, and submarine volcano near Mahengetan not far from Sangir Island. Mount Awu not considered dangerous, Mahengetan considered active and dangerous by local volcanologist."

Card 0048 (18 September 1968) Eruption started on 6 September

The following cable report was received on 16 September 1968. "Submarine volcano (Banua Wuhu) near island Mahengetang, Sangihe Islands, Celebes Sea, Indonesia, started erupting on 6 September 1968, showing activity, and decreasing intensity."

09/1968 (BVE 8) Small submarine eruption on 5 September

A small submarine eruption began at 1600 (local time) on 5 September 1968; no end date given. Ocean water near the crater became hot and turbid. The eruption was preceded by an earthquake at 1430 the same day.

10/1968 (CSLP 33-68) Only solfatara activity; sea surface has not been reached

Card 0120 (11 October 1968) Only solfatara activity; sea surface has not been reached

"Report on the observation of 14 September, the activity of Banua-wuhu Mahangetang is just in solfatara stage. As far as volcanological service knows it has not risen above the surface of the sea."

Information Contact: Kusmadinata, Indonesia Volcanological Service.

The Banua Wuhu submarine volcano in the Sangihe Islands rises more than 400 m from the sea floor to form a shoal less than 5 m below sea level. Several ephemeral islands were constructed during the 19th and 20th centuries. An island 90 m high was formed in 1835, but dwindled to only a few rocks by 1848. A new island formed in 1889 was 50 m high in 1894. Five new craters were formed during an eruption that built a new island in 1904. Another new island that formed in 1919 had disappeared by 1935.
