Harra Es-Sawad
Harra es-Sawad, or the "Shuqra Volcanic Field", is a large trachybasaltic volcanic field that runs along the Gulf of Aden. Nearby is the city of Shuqrah. Morphology The field stretches for around , contains around 100 volcanic cones, and is orientated on a WSW-ENE line. This has produced a lava field, which is mostly Holocene in age, and covers faulted basement limestone. Many of the fields cones are young and uneroded. History The only eruption that has been noted in historical times occurred in 1253. This eruption was a large VEI 3 eruption, although it was poorly documented. Given the age of the field, other eruptions may have occurred in the recent past. See also * Hadhramaut Mountains * List of volcanoes in Yemen This is a list of active and extinct volcanoes in Yemen.

Yemen
Yemen (; ar, ٱلْيَمَن, al-Yaman), officially the Republic of Yemen,, ) is a country in Western Asia. It is situated on the southern end of the Arabian Peninsula, and borders Saudi Arabia to the Saudi Arabia–Yemen border, north and Oman to the Oman–Yemen border, northeast and shares maritime borders with Eritrea, Djibouti, and Somalia. Yemen is the second-largest Arabs, Arab sovereign state in the peninsula, occupying , with a coastline stretching about . Its constitutionally stated Capital city, capital, and largest city, is Sanaa. As of 2021, Yemen has an estimated population of some 30.4 million. In ancient times, Yemen was the home of the Sabaeans, a trading state that included parts of modern-day Ethiopia and Eritrea. Later in 275 AD, the Himyarite Kingdom was influenced by Judaism. Christianity arrived in the fourth century. Islam spread quickly in the seventh century and Yemenite troops were crucial in the early Islamic conquests. Several Dynasty, dynasties ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of Yemen
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 sli ...

Sarawat Mountains
The Sarawat Mountains ( ar, جِبَالُ ٱلسَّرَوَاتِ, Jibāl as-Sarawāt), also known as the Sarat, is a part of the Hijaz mountains in the western part of the Arabian Peninsula. In a broad sense, it runs parallel to the eastern coast of the Red Sea, and thus encompasses the mountains of Fifa', 'Asir and Taif (which can be seen as including the Midian Mountains). In a narrow sense, the Sarawat start in Taif city in Saudi Arabia, and extend to the Gulf of Aden in the south, running along the entire western coast of Yemen, in what used to be North Yemen, and extend eastwards into part of what used to be South Yemen, thus running parallel to the Gulf of Aden. Geology These mountains are mainly rocky though some contain vegetation. Many of the peaks are fairly young and jagged, but some are smoother from weathering. Nearing the Yemeni border, the Sarawat begin to spread into individual peaks, and the Hejaz turns from a cliff to a gradual ascent up to the Yemeni Pl ...

Hadhramaut Mountains
Hadhramaut ( ar, حَضْرَمَوْتُ \ حَضْرَمُوتُ, Ḥaḍramawt / Ḥaḍramūt; Hadramautic: 𐩢𐩳𐩧𐩣𐩩, ''Ḥḍrmt'') is a region in South Arabia, comprising eastern Yemen, parts of western Oman and southern Saudi Arabia. The name is of ancient origin, and is retained in the name of the Yemeni Governorate of Hadhramaut. The people of Hadhramaut are called Hadhrami. They formerly spoke Hadramautic, an old South Arabian language, but they now predominantly speak Hadhrami Arabic, which has much influence from Hadramautic. Etymology The origin of the name of ''Ḥaḍramawt'' is not exactly known, and there are numerous competing hypotheses about its meaning. The most common folk etymology is that the region's name means "death has come," from ar, حَضَر, ḥaḍara, lit=he came and ar, مَوْت, mawt, lit=death, though there are multiple explanations for how it came to be known as such. One explanation is that this is a nickname of 'A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Association Of Volcanology And Chemistry Of The Earth's Interior
The International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) is a learned society that focuses on research in volcanology, efforts to mitigate volcanic disasters, and research into closely related disciplines, such as igneous geochemistry and petrology, geochronology, volcanogenic mineral deposits, and the physics of the generation and ascent of magmas in the upper mantle and crust. It is one of eight constituent associations of the International Union of Geodesy and Geophysics (IUGG). IAVCEI is run by an executive committee whose membership changes every four years. The Executive determines policies for the Association, enacting them through a series of commissions and task groups. '' Bulletin of Volcanology'' is the journal of IAVCEI.IAVCEI About Us.

Volcanic Field
A volcanic field is an area of Earth's crust that is prone to localized volcanic activity. The type and number of volcanoes required to be called a "field" is not well-defined. Volcanic fields usually consist of clusters of up to 100 volcanoes such as cinder cones. Lava flows may also occur. They may occur as a monogenetic volcanic field or a polygenetic volcanic field. Description Alexander von Humboldt observed in 1823 that geologically young volcanoes are not distributed uniformly across the Earth's surface, but tend to be clustered into specific regions. Young volcanoes are rarely found within cratons, but are characteristic of subduction zones, rift zones, or in ocean basins. Intraplate volcanoes are clustered along hotspot traces. Within regions of volcanic activity, volcanic fields are clusters of volcanoes that share a common magma source. Scoria cones are particularly prone to cluster into volcanic fields, which are typically in diameter and consist of several tens ...
