A cluster of cinder cones on the SW rift of Halla shield volcano is part of more than 360 cones that were erupted on the flanks of the volcano during the third and last stage of activity at Halla. Most of the flank cones were erupted along the SW-NE-trending rift zone that forms the axis of the island. The basaltic scoria cones are typically 150-200 m in height and are relatively uneroded.

A waterfall plunging over a trachytic lava flow is a popular tourist destination on Cheju Island. An extensive lava plateau underlies the Halla shield volcano and extends to the coast of the 40 x 80 km island. The 1950-m-high Halla shield dominates the center of the island and has been active from the Pleistocene until historical time.

The massive Halla shield volcano, seen here from the south, forms much of the 40 x 80 km Cheju Island, which lies 90 km south of the Korean Peninsula. More than 360 late-Pleistocene and Holocene basaltic parasitic cones dotting the flanks of the low-angle volcano were erupted primarily along the long axis of the NE-SW-trending island. Most of these are scoria cones, but about 10 along the coast of the island are Pleistocene tuff rings and tuff cones. Flank eruptions continued into historical time, with the final two taking place during the 11th century.

Prominent columnar jointing is visible on the steep sides of a trachytic lava dome on the southern coast of Cheju Island. A cluster of trachytic lava domes were erupted near the end of the second stage of activity of Halla volcano, during which the 1950-m-high Halla shield volcano was formed in the center of the island.

Snow-capped Halla shield volcano is seen here from the north, near Cheju city, the largest on Cheju Island. Voluminous lava flows from Halla and an underlying lava plateau form the entire 40 x 80 km Cheju Island. The volcano is capped by the 400-m-wide Backlockdam summit crater and its flanks are dotted by hundreds of satellitic cones, some of which form small islands offshore.
