Lake Bandung
Lake Bandung is a paleo lake believed once existed between 126,000 to 20,000 years before present, located in and around Bandung city, Priangan highlands, West Java, Indonesia. Today the lake had dried-out and revealed the bottom of a geological basin known as Bandung basin, mostly filled with habitation and industrial areas, paddy fields and orchards. It is believed that this low-lying basin has caused the southern suburbs of Bandung suffers seasonal floodings during rainy season, as the Citarum river that formed the lowermost backbone of the basin overwhelmed and swells.
==Bandung basin formation==
Bandung basin is an ellips-formed geological basin measuring 60 kilometres east-west, and 40 kilometres north-south, spanned from Padalarang in the west to Nagreg in the east, from mount Tangkuban Perahu in the north to Mount Malabar in the south. The Bandung basin is surrounded by volcanic domes formed during quaternary period in most sides, only western parts is dated older, its stones was formed during neogene period, mostly consist of limestones, creating Padalarang karst mountain.〔 It is suggested that Bandung basin is a multiple volcanic caldera system, created by both volcanic and tectonic activity as there are numbers of tectonic fault crossing the Priangan highland. For example, there is a Lembang fault that runs west-east axis located immediately north of Bandung city under Lembang town. Sedimentation of Bandung basin started 126,000 years before present which suggested that Bandung paleo-lake was first formed during this time.
