Adwa (volcano)
''Adwa'' (also known as Caaduba, Amoissa, or Dabita) (1733 m/5686 ft.) is a stratovolcano in Ethiopia, located in the western Somali Region region and has a 4 by 5 km caldera. Due to the location of the volcano near the boundary between Afar and Issa tribes, little is known about the past and present behavior of the volcano. However, an earthquake and InSAR study conducted by Derek Keir and colleagues shows that a magma intrusion around 5 km deep and 8 km long emanated away from the eastern side of the volcano in May 2000.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Somali Region
The Somali Region ( so, Deegaanka Soomaalida, am, ሱማሌ ክልል, Sumalē Kilil, ar, المنطقة الصومالية), also known as Soomaali Galbeed (''Western Somalia'') and officially the Somali Regional State, is a regional state in eastern Ethiopia. Its territory is the largest after Oromia Region. The regional state borders the Ethiopian regions of Afar and Oromia and the chartered city Dire Dawa (Dire Dhawa) to the west, as well as Djibouti to the north, Somaliland to the northeast, Somalia to the south; and Kenya to the southwest. Jijiga is the capital of the Somali Region. The capital was formerly Gode, until Jijiga became the capital in 1995 on account of political considerations. The Somali regional government is composed of the executive branch, led by the President; the legislative branch, which comprises the State Council; and the judicial branch, which is led by the State Supreme Court.

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish ', and Latin ', mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afar People
The Afar ( aa, Qafár), also known as the Danakil, Adali and Odali, are a Cushitic-speaking ethnic group inhabiting the Horn of Africa. They primarily live in the Afar Region of Ethiopia and in northern Djibouti, as well as the entire southern coast of Eritrea. The Afar speak the Afar language, which is part of the Cushitic branch of the Afroasiatic family. Afars are the only inhabitants of the Horn of Africa whose traditional territories border both the Red Sea and the Gulf of Aden. History Early history The earliest surviving written mention of the Afar is from the 13th-century Andalusian writer Ibn Sa'id, who reported that they inhabited the area around the port of Suakin, as far south as Mandeb, near Zeila. They are mentioned intermittently in Ethiopian records, first as helping Emperor Amda Seyon in a campaign beyond the Awash River, then over a century later when they assisted Emperor Baeda Maryam when he campaigned against their neighbors the Dobe'a.

Interferometric Synthetic-aperture Radar
Interferometric synthetic aperture radar, abbreviated InSAR (or deprecated IfSAR), is a radar technique used in geodesy and remote sensing. This geodetic method uses two or more synthetic aperture radar (SAR) images to generate maps of surface deformation or digital elevation, using differences in the phase of the waves returning to the satellite or aircraft. The technique can potentially measure millimetre-scale changes in deformation over spans of days to years. It has applications for geophysical monitoring of natural hazards, for example earthquakes, volcanoes and landslides, and in structural engineering, in particular monitoring of subsidence and structural stability. Technique Synthetic aperture radar Synthetic aperture radar (SAR) is a form of radar in which sophisticated processing of radar data is used to produce a very narrow effective beam. It can be used to form images of relatively immobile targets; moving targets can be blurred or displaced in the formed im ...
