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 1960 Agadir earthquake occurred 29 February at 23:40 Western European Time near the city of Agadir, located in western Morocco on the shore of the Atlantic Ocean. Despite the earthquake's moderate Mw scale magnitude of 5.8, its relatively shallow depth (15.0 km) resulted in strong surface shaking, with a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. Between 12,000 and 15,000 people (about a third of the city's population of the time) were killed and another 12,000 injured with at least 35,000 people left homeless, making it the most destructive and deadliest earthquake in Moroccan history. Particularly hard hit were Founti, the Kasbah, Yachech (iḥšaš) and the Talbordjt area. The earthquake's shallow focus, close proximity to the port city of Agadir, and unsatisfactory construction methods were all reasons declared by earthquake engineers and seismologists as to why it was so destructive.
