Gunung Halla

Halla

Gunung api perisai · South Korea · 1919 m

The massive Halla shield volcano, seen here from the south, forms much of the 40 x 80 km Cheju Island, which lies 90 km S of the Korean Peninsula. More than 360 late-Pleistocene and Holocene basaltic cones on 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 are Pleistocene tuff rings and tuff cones. Flank eruptions continued into historical time, with the final two taking place during the 11th century.

Ringkasan geologi

The massive Halla shield volcano forms much of the 40 x 80 km Cheju (Jeju) Island, which lies 90 km S of the Korean Peninsula. Eruptions during the Pliocene and Pleistocene built a lava plateau above the roughly 100-m-deep continental shelf on which the basaltic-to-trachytic edifice was constructed. A 400-m-wide crater truncates the summit. About 360 late-Pleistocene and Holocene basaltic cones across the flanks were erupted primarily along the long axis of the ENE-WSW-trending island. Most of these are scoria cones, but about 20 along the coast or offshore are Pleistocene-to-Holocene tuff rings and tuff cones; lava domes also occur. The latest two eruptions took place during the 11th century.
