Volcano
A volcano is a rupture 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 most 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 can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

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 ...

Geographic Coordinates
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...

Dubbi Volcano
The Dubbi Volcano is a stratovolcano located in the Southern Red Sea Region of Eritrea. Its peak elevation is . There have been four known eruptions. In 1400 lava was determined to have reached the Red Sea while in 1861 ash was thrown over from the volcano. Two further events were suspected between 1861 and the 20th century. On June 13, 2011 an ash cloud that had some influence on air travel was attributed to Dubbi. However, more accurate satellite imagery later showed that Nabro was the volcano that had erupted.Blog articles"Eritrea eruption update: Nabro volcano erupts (updated)" See also * List of volcanoes in Eritrea *List of stratovolcanoes A list of stratovolcanoes follows below.

Gufa Volcano
The Gufa Volcano is a volcanic field located in the Southern Red Sea Region of Eritrea near the border with Djibouti. The peak elevation is 600 m where lava flows are visible. The last eruption of the volcano was inferred to be during the Holocene era. See also * List of volcanoes in Eritrea This is a list of active and extinct volcanoes in Eritrea.

Mousa Ali
Mousa Ali ( ar, موسى علي) is a stratovolcano located on the tri-point of Ethiopia, Eritrea and Djibouti. The volcano is the highest point in Djibouti. The volcano's summit is truncated by a caldera, which contains rhyolitic lava domes and lava flows. The last known eruption occurred before the Holocene era. Mousa Ali is situated at the tri-point of the Tadjourah Region of Djibouti, the Southern Red Sea Region of Eritrea, and the Afar Region of Ethiopia. Geography The mountain has two distinct summits, the higher being the south one with an elevation of 2,021 metres The north summit in Ethiopia has an elevation of 1,871 metres. Both summits are separated by a large caldera, about 1 km (0.71 mi) wide and 1514 metres deep. Mousa Ali, in the northern part of the Great Rift Valley region, has Eritrea on its northern flank, Ethiopia on the west, and Djibouti the east and south. The Djiboutian town of Dorra is 36 km to the south-southeast, the Ethiopian volca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nabro Volcano
The Nabro Volcano is an active stratovolcano in the Southern Red Sea Region of Eritrea. It is located at the south-east end of the Danakil Alps in the Danakil Depression. Before its 2011 eruption, the volcano was widely believed to be extinct. Geology Part of the Afar Triangle, the Nabro Volcano is one of many volcanic caldera complexes in the northeasternmost part of the East African Rift valley region. The twin calderas likely formed during an eruption of about 20 to 100 cubic kilometres consisting of ignimbrite, although the date of their formation is unknown. The subaerial volume of volcanic material within the Nabro Volcanic Range is likely on the order of . 2011 eruption Although it had undergone no historically reported eruptions,"Eruption at Nabro Volcano, Eritrea" NASA Earth ...

Volcanoes Of Eritrea
A volcano is a rupture 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.
