The morphology of Mount Batur is closely related to the volcanic evolution that occurred and some are influenced by structural land conditions. The natural landscape of Mount Batur is composed of basalt andesite lava deposits. Lake Batur is one of the effects of the collapse that occurred in the Batur Caldera. This morphology was formed as a result of progressive volcanic activity that carried the rock inside until it finally collapsed into a caldera basin. After this subsidence occurred, several conditions such as Mount Abang were formed. Mount Abang, is part of the body of Mount Batur that did not collapse. In some places, the land is filled with lava covered by pyroclastic deposits [6].
The distribution of rocks produced from Mount Batur can be divided into 5 periods, namely, period I Tertiary period, period II Quaternary period (pre-caldera), period III caldera formation period I, period IV caldera formation period II, and period V post-caldera period. The oldest rocks exposed are the pyroclastic flow deposits of Bukit Jangkrik, these rocks are exposed in the southern part. The next rock that is exposed is the Cempaga Lava which is composed of olivine basalt, this rock is exposed slightly in the south. The younger rock is Tejakulak Lava which is exposed in the north, composed of porphyritic olivine basalt, bright grey, phenocrysts (about 40%) characterised by large euhedral – subhedral olivine with subhedral plagioclase (less than 2 mm) [7].
The caldera of Mount Batur is enclosed from all directions, and is one of the largest and most beautiful calderas in the world [8]. The caldera rim ranges in height from 1267 m to 2152 m (Mount Abang Peak). Inside Caldera I, Caldera II is formed in a circular shape with a centre line of approximately 7 km. The base of Kaldera II is located between 120 – 300 m lower than Undak Kintamani (base of Kaldera I). Inside the caldera is a crescent-shaped lake. According to Van Bemmelen (1949), the lake is thought to have formed simultaneously with the formation of Kaldera II.
