Minor submarine eruptions were reported at two locations on 15 January 1854, when the ship "Susquehannah" passed the southern tip of Taiwan. Little is known about volcanism in this area, although the Catalog of Active Volcanoes of the World (Kuno, 1962) and Liu (1986, pers. comm.) mentioned an 1854 eruption here, based on accounts in Sapper (1917). Liu listed a depth of 115 m for this volcano. Both the nature of the reported eruptive phenomena and its location are uncertain due to the lack of sufficient detail in the original report.

Submarine eruptions were reported in 1854 at a location SE of the southern tip of Taiwan (lower left). Eruptions were seen at two places when a ship passed the southern tip of Taiwan. The depth at this location is about 115 m. Lan Yü Island, about 130 km east of the southern tip of Taiwan, lies at the far right in this NASA Landsat image (with north to the top). The city of Hengch'un lies along the west coast of the southern peninsula of Taiwan, above the cloud bank.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
