Lake Zengena
Zengena Lake () is a crater lake located at in the Awi Zone of the Amhara Region in Ethiopia. It is situated between the towns of Injibara and Kessa, only 200 m from the Addis Ababa-Bahir Dar highway at an elevation of 2500 m. The diameter of the lake is roughly 1 km. With a maximum depth of 166 m, it is the second deepest lake in Ethiopia after Lake Shala. Its rim is made of unconsolidated ash deposits. Zengena Lake is most likely a maar A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma).

Volcanic Crater Lake
A volcanic crater lake is a lake in a volcanic crater, crater that was formed by explosive eruption, explosive activity or a caldera, collapse during a types of volcanic eruptions, volcanic eruption. Formation Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Lakes in maars fill medium-sized craters where an eruption deposited debris around a vent. Crater lakes form as the created depression, within the Rim (craters), crater rim, is filled by water. The water may come from Precipitation (meteorology), precipitation, groundwater circulation (often Hot Spring, hydrothermal fluids in the case of volcanic craters) or melted ice. Its level rises until an equilibrium is reached between the rates of incoming and outgoing water. Sources of water loss singly or together may include evaporation, subsurface seepage, and, in places, surface leakage or overflow when the lake level reaches the lowest point on its rim. At such a saddle location, the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agew Awi Zone
Agew Awi () is a zone in the Amhara Region of Ethiopia. It is named for the Awi sub-group of the Agaw people, some of whom live in this Zone. Agew Awi Zone is bordered on the west by Benishangul-Gumuz Region, on the north by North Gondar Zone and on the east by West Gojjam.

Injibara
Injibara (Amharic: እንጅባራ) is a town in Ethiopia. It is the administrative center of the Agew Awi Zone in the Amhara Region. Injibara is located at , in Banja Shekudad woreda at an elevation of above sea level. Injibara is situated in a predominantly mountainous location. Mount Zerehi, one of many massive stone monoliths found in the area, is to the west of the Bahir Dar road as it enters the town. Another geographical feature of the area is the Zengena Lake, Zengena crater lake just south of the town. The hills and valleys receive high amounts of rain, especially in the rainy season. This high rainfall permits farmers to grow multiple crops a year. With this rainy weather comes hail, however, which is a major problem for the local farmers. Based on figures from th2007 census, Injibara has an estimated total population of 21,065, of whom 10,596 are males and 10,469 are females. History Injibara was the scene of (in the words of Sven Rubenson) "one of the most blood ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Addis Ababa
Addis Ababa (; ,) is the capital city of Ethiopia, as well as the regional state of Oromia. With an estimated population of 2,739,551 inhabitants as of the 2007 census, it is the largest city in the country and the List of cities in Africa by population, eleventh-largest in Africa. Addis Ababa is a highly developed and important cultural, artistic, financial and administrative center of Ethiopia. It is widely known as one of Africa's major capitals. The founding history of Addis Ababa dates back to the late 19th century by Menelik II, Negus of Shewa, in 1886 after finding Mount Entoto unpleasant two years prior. At the time, the city was a resort town; its large mineral spring abundance attracted nobilities of the empire and led them to establish permanent settlement. It also attracted many members of the working classes – including artisans and merchants – and foreign visitors. Menelik II then formed his Menelik Palace, imperial palace in 1887.

Lake Shala
Lake Shala (also spelled Shalla) is an alkaline lake located in the Ethiopian Rift Valley, in the Abijatta-Shalla National Park. Overview The lake is 28 kilometers long and 12 wide,''Statistical Abstract of Ethiopia for 1967/68'' with a surface area of 329 square kilometers.Baxter, R. M. "Lake Morphology and Chemistry", in Taylor, W.D. and Tudorancea, C., eds. ''Ethiopian Rift Valley Lakes'' (Leiden: Backhuys Publishers, 2002) It has a maximum depth of 266 meters and is at an elevation of 1,558 meters. As such, it is the deepest of Ethiopia's Rift Valley lakes. Known for the sulphur springs on the lake bed, its islands are inhabited by great white pelicans, one being known as Pelican Island. Lake Shala is surrounded by hot springs filled with boiling water, and the earth surrounding the lake is filled with cracks due to erosion and earthquakes. Due to steam rising from the boiling water in the springs, the atmosphere around the lake is relatively foggy. Various species ...

Maar
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma). A maar characteristically fills with water to form a relatively shallow crater lake, which may also be called a maar.David S.G. Thomas and Andrew Goudie (eds.), ''The Dictionary of Physical Geography'' (Oxford: Blackwell, 2000), 301. . Maars range in size from across and from deep. Most maars fill with water to form natural lakes. Most maars have low rims composed of a mixture of loose fragments of volcanic rocks and rocks torn from the walls of the diatreme. Etymology The name ''maar'' comes from a Moselle Franconian dialect word used for the circular lakes of the Daun area of Germany. The word evolved from its first use in German in the modern geological sense in 1819 and is now used in English and in the geological sciences as the term for the explosion crater, even if water from rainfall might alway ...

Volcanic Crater Lakes
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching an ...
