Mount Nyiragongo ( neer-ə-GONG-go) is an active stratovolcano with an elevation of 3,470 m (11,385 ft) in the Virunga Mountains associated with the Albertine Rift. It is located inside Virunga National Park, in the Democratic Republic of the Congo, about 12 km (7.5 mi) north of the town of Goma and Lake Kivu and just west of the border with Rwanda. The main crater is about two kilometres (1 mi) wide and usually contains a lava lake. The crater presently has two distinct cooled lava benches within the crater walls – one at about 3,175 m (10,417 ft) and a lower one at about 2,975 m (9,760 ft). Nyiragongo's lava lake has at times been the most voluminous known lava lake in recent history. The depth of the lava lake varies considerably. A maximum elevation of the lava lake was recorded at about 3,250 m (10,660 ft) prior to the January 1977 eruption – a lake depth of about 600 m (2,000 ft). Following the January 2002 eruption, the lava lake was recorded at a low of about 2,600 m (8,500 ft), or 900 m (3,000 ft) below the rim. The level has gradually risen since then. Nyiragongo and nearby Nyamuragira are together responsible for 40 per cent of Africa's historical volcanic eruptions.

The Chalisa famine of 1783–1784 in the Indian subcontinent followed unusual El Niño events that began in 1780 and caused droughts throughout the region. Chalisa (literally, 'of the fortieth' in Hindustani) refers to the Vikram Samvat calendar year 1840 (1783). The famine affected many parts of North India, especially the Delhi territories, present-day Uttar Pradesh, Eastern Punjab, Rajputana, and Kashmir, then all ruled by different Indian rulers. The Chalisa was preceded by a famine in the previous year, 1782–1783, in South India, including Madras City and surrounding areas (under British East India Company rule) and in the extended Kingdom of Mysore (under the rule of Haider Ali and Tipu Sultan). Together the two famines may have depopulated many regions of India, including, for example, 17 per cent of the villages in the Sirkali region of present-day Tamil Nadu, 60 per cent of the villages in the middle Doab of present-day Uttar Pradesh, and over 30 per cent of the villages in the regions around Delhi. It is thought that up to 11 million people may have died in the two famines.
