Lake Segara Anak
The surface of Segara Anak is 2,004 metres (6,575 ft) above mean sea level (AMSL) and is Indonesia's second-highest caldera lake with an active volcano. The peak of Gunung Baru Jari is 2,376 metres (7,795 ft) AMSL. The lake covers 45 square kilometres (17 sq mi), with dimensions of 7.5 by 6.0 kilometres (4.7 by 3.7 mi), and has a maximum depth of 230 metres (750 ft).
Fish breeding
There were no fish in Segara Anak. In 1969, volcanologists from the Geological Society of London examined the lake and recommended the cultivation of fish. In 1985, the Nusa Tenggara Barat provincial government began breeding fish in the lake. The fish bred rapidly and the lake became home to millions of tilapia and carp. Segara Anak is today a popular spot for fishing, and some locals make a living from this.

Mount Samalas
The estimated height of Mount Samalas before its 1257 eruption was 4,200 metres (13,800 ft). According to a 2013 study, the eruption destroyed the mountain by ejecting up to 10 cubic miles (42 km) of Dense rock equivalent or 200 cubic kilometres (48 cu mi) of rock into the atmosphere. The eruption was one of the largest during the last few thousand years, with a probable Volcanic Explosivity Index of 7. The eruption may have been the cause of decreased global temperatures for a few years and may have even been a triggering factor for the Little Ice Age.
