Photo Gallery

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.
