The 2008 Lake Kivu earthquake shook several countries in Africa's Great Lakes region at 07:34:12 (GMT) on February 3. It measured 5.9 on the moment magnitude scale. The epicentre was 20 kilometres (12 mi) north of Bukavu at Lake Kivu in the Democratic Republic of Congo. [4]

Tectonic summary

According to the USGS, [5]

The earthquake occurred in the Western Rift of the East African rift system. The East African rift system is a diffuse, approximately 3000-km-long, zone of crustal extension that passes through eastern Africa from Djibouti and Eritrea on the north to Malawi on the south and that constitutes the boundary between the Africa plate on the west and the Somalia plate on the east. At the earthquake's latitude, the Africa and Somalia plates are spreading apart at a rate of about four millimeters per year. The earthquake occurred near Lake Kivu, the basin of which was created by normal faulting similar to that which produced the February 3 earthquake. The largest earthquake to have occurred in the rift system since 1900 had a magnitude of about 7.6. The epicenter of the February 3, 2008, earthquake is within several tens of kilometres (miles) of the epicenter of a magnitude 6.2 earthquake that killed two people in Goma in October 2002. Earthquakes within the East African rift system occur as the result of both normal faulting and strike-slip faulting.

Details

At least 25 people were confirmed dead in Rwanda, with a further 200 seriously injured. Ten people were killed when a church collapsed in the Rusizi District of Western Province in Rwanda, according to Rwanda radio. [6] In the Democratic Republic of Congo at least 5 died and 149 were seriously injured. [7]

Lake Kivu is one of the African Great Lakes. It lies on the border between the Democratic Republic of the Congo and Rwanda, and is in the Albertine Rift, the western branch of the East African Rift. Lake Kivu empties into the Ruzizi River, which flows southwards into Lake Tanganyika. In 1894, German officer and colonial ruler Gustav Adolf von Götzen was the first European to discover the lake.

The 2005 Lake Tanganyika earthquake occurred at 14:19:56 local time on 5 December with a moment magnitude of 6.8 and a maximum Mercalli intensity of X (Extreme).

The 1999 Hector Mine earthquake occurred in Southern California, United States, on October 16 at 02:46:50 PDT. Its moment magnitude was 7.1 and the earthquake was preceded by 12 foreshocks, the largest of which had a magnitude of 3.8. The event is thought to have been triggered by the 1992 Landers earthquake which occurred seven years earlier. It also deformed nearby faults vertically and horizontally. The earthquake's hypocenter was at a depth of 20 kilometers and its epicenter at 34.603° N 116.265° W.

The 2008 Ziarat earthquakes hit the Pakistani province of Balochistan on October 29 with a moment magnitude of 6.4. The US Geological Survey reported that the first earthquake occurred 60 km (37 mi) north of Quetta and 185 km (115 mi) southeast of the Afghanistan city of Kandahar at 04:09 local time at a depth of 15 km (9.3 mi), at 30.653°N, 67.323°E. It was followed by another shallower magnitude 6.4 earthquake at a depth of 14 km (8.7 mi) approximately 12 hours after the initial shock, at 30.546°N, 67.447°E. 215 people were confirmed dead. More than 200 were injured, and 120,000 were rendered homeless. Qamar Zaman Chaudhry, director general of Pakistan Meteorological Department, stated the quake epicenter was 70 miles (110 km) north of Quetta, and about 600 km (370 mi) southwest of Islamabad.

The 2009 Swan Islands earthquake occurred on May 28 at 02:24:45 AM local time with a moment magnitude of 7.3 and a maximum Mercalli intensity of VII. The epicenter was located in the Caribbean Sea, 64 kilometres (40 mi) northeast of the island of Roatán, 19 miles northeast of Port Royal, Isla de Bahias, 15 miles northwest of Isla Barbaretta, and 130 kilometres (81 mi) north-northeast of La Ceiba.

Lake Kivu belongs to the western branch of the East African Rift System (EARS). The western branch is usually divided into several segments, and Lake Kivu belongs to the northern segment.
