2009 Karonga Earthquakes
The 2009 Karonga earthquakes occurred near Karonga, Malawi in December 2009 near the northern tip of Lake Malawi in southeast Africa. The earthquakes were one of the biggest in the history of Malawi. Geology Being in the southern East African Rift, the 100 km-long Livingstone Fault marks the limit of the Karonga Basin. The earthquakes, located at about 50 km west of the Livingstone Fault, occurred along previously unknown buried faults beneath the Quaternary unconsolidated sediments. Satellite-based geophysical investigations indicated that one of the west dipping faults which cut the Karonga Basin might have ruptured during the earthquakes. The studies also estimated a maximum slip of about 120 cm at 3–5 km depth with no evidence of dike-injection related activity associated with many earthquakes in Eastern Africa. Another study utilized aeromagnetic data to image the basement structure around the rupture area and found that multiple buried faults rupture ...

Central Africa Time
Central Africa Time or CAT, is a time zone used in north central, east central and southern Africa. Central Africa Time is two hours ahead of Coordinated Universal Time ( UTC+02:00), which is the same as the adjacent South Africa Standard Time, Egypt Standard Time, Eastern European Time, Kaliningrad Time and Central European Summer Time. As this time zone is in the equatorial and tropical regions, there is little change in day length throughout the year and so daylight saving time is not observed. Central Africa Time is observed by the following countries: * * * (eastern provinces) * * * * * * * * The following countries in Africa also use an offset of UTC+02:00 all-year round: * (observes South African Standard Time) * (observes South African Standard Time) * (observes Eastern European Time) * (observes South African Standard Time) See also * Egypt Standard Time, an equivalent (except during daylight savings) time zone covering Egypt, also at UTC+02:00 * Kaliningrad T ...

Karonga
Karonga is a township in the Karonga District in Northern Region of Malawi. Located on the western shore of Lake Nyasa, it was established as a slaving centre sometime before 1877. As of 2018 estimates, Karonga has a population of 61,609. The common and major language spoken in this district is the Tumbuka language, which is also a regional language of Northern Malawi. History Pre-historic tools and remains of hominids discovered in Malawi's remote northern district of Karonga provides further proof that the area could be the cradle of humankind. Professor Friedemann Schrenk of the Goethe University in Frankfurt told Reuters News that two students working on the excavation site in September 2009 had discovered prehistoric tools and a tooth of a hominid. "This latest discovery of prehistoric tools and remains of hominids provides additional proof to the theory that the Great Rift Valley of Africa and perhaps the excavation site near Karonga can be considered the cradle of ...

Malawi
Malawi, officially the Republic of Malawi, is a landlocked country in Southeastern Africa. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south, and southwest. Malawi spans over and has an estimated population of 21,240,689 (as of 2024). Lilongwe is its capital and largest city, while the next three largest cities are Blantyre, Mzuzu, and Zomba, the former capital. The part of Africa now known as Malawi was settled around the 10th century by the Akafula, also known as the Abathwa. Later, the Bantu groups came and drove out the Akafula and formed various kingdoms such as the Maravi and Nkhamanga kingdoms, among others that flourished from the 16th century. In 1891, the area was colonised by the British as the British Central African Protectorate, and it was renamed '' Nyasaland'' in 1907. In 1964, Nyasaland became an independent country as a Commonwealth realm under Prime Minister Hastings Banda, and was rena ...

Lake Malawi
Lake Malawi, also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique, () is an African Great Lakes, African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania. It is the List of lakes by volume, fourth largest freshwater lake in the world by volume, the List of lakes by area, ninth largest lake in the world by area and the third largest and List of lakes by depth, second deepest lake in Africa. Lake Malawi is home to more species of fish than any other lake in the world, including at least 700 species of cichlids.Turner, Seehausen, Knight, Allender, and Robinson (2001). "How many species of cichlid fishes are there in African lakes?" ''Molecular Ecology'' 10: 793–806.

East African Rift
The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. It was formerly considered to be part of a larger Great Rift Valley that extended north to Asia Minor. A narrow zone, the rift is a developing divergent tectonic plate boundary where the African plate is in the process of splitting into two tectonic plates, called the Somali plate and the Nubian plate, at a rate of per year. The rift system consists of three microplates, the Victoria microplate to the north, and the Rovuma and Lwandle microplates to the south. The Victoria microplate is rotating anti-clockwise with respect to the African plate. Its rotation is caused by the configuration of mechanically weaker and stronger lithospheric regions in the EARS. Many of the African Great Lakes lie within the Rift Valley. Extent A series of distinct rift basins, the East A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tanzania
Tanzania, officially the United Republic of Tanzania, is a country in East Africa within the African Great Lakes region. It is bordered by Uganda to the northwest; Kenya to the northeast; the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west.

Soil Liquefaction
Soil liquefaction occurs when a cohesionless saturated or partially saturated soil substantially loses Shear strength (soil), strength and stiffness in response to an applied Shear stress, stress such as shaking during an earthquake or other sudden change in stress condition, in which material that is ordinarily a solid behaves like a liquid. In soil mechanics, the term "liquefied" was first used by Allen Hazen in reference to the 1918 failure of the Calaveras Dam in California. He described the mechanism of flow liquefaction of the embankment dam as: The phenomenon is most often observed in saturated, loose (low density or uncompacted), sandy soils. This is because a loose sand has a tendency to Compressibility, compress when a force, load is applied. Dense sands, by contrast, tend to expand in volume or 'Reynolds' dilatancy, dilate'. If the soil is saturated by water, a condition that often exists when the soil is below the water table or sea level, then water fills the gap ...

Earthquakes In Africa
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the epicen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
