Northern Red Sea
The Northern Red Sea Region (, it, Regione del Mar Rosso Settentrionale, ) is an administrative region of Eritrea. It lies along the northern three quarters of the Red Sea, and includes the Dahlak Archipelago and the coastal city of Massawa. As of 2005, the region had a population of 653,300 compared to a population of 576,200 in 2001. The net growth rate was 11.80 per cent. The total area of the province was 27800.00 km2 and the density was 23.50 persons per km2. Geography The Northern Red Sea Region borders the Anseba, Maekel (Central) and Debub (Southern) regions to the west, and the Southern Red Sea Region to the east. It has an area of around 27,800 km². The lowest point in Eritrea, Lake Kulul, is in this region. The topography of the region has coastal plains, which are hotter than the regions around the highland plateau. There are two rainy seasons, the heavier one during summer and the lighter one during spring. The climate and geography of the region alon ...

Eritrea
Eritrea ( ; ti, ኤርትራ, Ertra, ; ar, إرتريا, ʾIritriyā), officially the State of Eritrea, is a country in the Horn of Africa region of Eastern Africa, with its capital and largest city at Asmara. It is bordered by Ethiopia in the south, Sudan in the west, and Djibouti in the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The nation has a total area of approximately , and includes the Dahlak Archipelago and several of the Hanish Islands. Human remains found in Eritrea have been dated to 1 million years old and anthropological research indicates that the area may contain significant records related to the evolution of humans. Contemporary Eritrea is a multi-ethnic country with nine recognised ethnic groups. Nine different languages are spoken by the nine recognised ethnic groups, the most widely spoken language being Tigrinya, the others being Tigre, Saho, Kunama, Nara, Afar, Beja, Bilen and Ar ...

Stratovolcano
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Regions Of Eritrea
The regions of Eritrea are the primary geographical divisions through which Eritrea is administered. Six in total, they include the Central, Anseba, Gash-Barka, Southern, Northern Red Sea and Southern Red Sea regions. At the time of independence in 1993 Eritrea was arranged into ten provinces. These provinces were similar to the nine provinces operating during the colonial period. In 1996, these were consolidated into six regions (''zobas''). Gash-Barka Region was the largest and the most densely populated region and is called the "bread-basket". The People's Front for Democracy and Justice or PFDJ (originally Eritrean People's Liberation Front) rules the country and its regions as a single-party totalitarian government. The regional and local elections are conducted on a periodic basis on a restricted framework. All men and women of any ethnic or religious background are eligible to vote. No parties or groups other than PFDJ are allowed to contest and the elections are presid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danakil Depression
The Danakil Depression is the northern part of the Afar Triangle or Afar Depression in Ethiopia, a geological depression that has resulted from the divergence of three tectonic plates in the Horn of Africa. Geology The Danakil Depression lies at the triple junction of three tectonic plates and has a complex geological history. It has developed as a result of Africa and Asia moving apart, causing rifting and volcanic activity. Erosion, inundation by the sea, the rising and falling of the ground have all played their part in the formation of this depression. Sedimentary rocks such as sandstone and limestone are unconformably overlain by basalt which resulted from extensive lava flows. IUGS geological heritage site In respect of it demonstrating 'the ongoing birth of an ocean witnessed through tectonics and volcanism in an extreme evaporite arid environment', the International Union of Geological Sciences (IUGS) included 'The Danakil Rift depression and its volcanism' in its assem ...

Mountains Of Eritrea
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain ...

Active Volcanoes
An active volcano is a volcano which is either erupting or is likely to erupt in the future. An active volcano which is not currently erupting is known as a dormant volcano. Overview Tlocene Epoch. Most volcanoes are situated on the Pacific Ring of Fire. An estimated 500 million people live near active volcanoes. ''Historical time'' (or recorded history) is another timeframe for ''active''. However, the span of recorded history differs from region to region. In China and the Mediterranean, it reaches back nearly 3,000 years, but in the Pacific Northwest of the United States and Canada, it reaches back less than 300 years, and in Hawaii and New Zealand it is only around 200 years. The incomplete ''Catalogue of the Active Volcanoes of the World'', published in parts between 1951 and 1975 by the International Association of Volcanology, uses this definition, by which there are more than 500 active volcanoes. , the Smithsonian Global Volcanism Program recognizes 560 volcanoes with ...
