2023 Morocco Earthquake
On 8 September 2023 at 23:11 DST (22:11 UTC), an earthquake with a moment magnitude of 6.9 and maximum Mercalli intensity of IX (''Violent'') struck Morocco's Al Haouz Province. The earthquake's epicenter was southwest of Marrakesh, near the town of Ighil and the Oukaïmeden ski resort in the Atlas Mountains. It occurred as a result of shallow oblique-thrust faulting beneath the mountain range. At least 2,960 deaths were reported, with most occurring outside Marrakesh. Damage was widespread, and historic landmarks in Marrakesh were destroyed. The earthquake was also felt in Spain, Portugal, and Algeria. It is the strongest instrumentally recorded earthquake in Morocco, the deadliest in the country since the 1960 Agadir earthquake, and the second-deadliest earthquake of 2023 after the Turkey–Syria earthquakes. Its magnitude also makes it the largest earthquake on the African continent since the 2006 7.0 Mozambique earthquake and the largest in North Africa since the 1980 ...

Atlas Mountains
The Atlas Mountains are a mountain range in the Maghreb in North Africa. They separate the Sahara Desert from the Mediterranean Sea and the Atlantic Ocean; the name "Atlantic" is derived from the mountain range, which stretches around through Morocco, Algeria and Tunisia. The mountains are associated with the Greek god Atlas (mythology), Atlas. The range's highest peak is Toubkal, which is in central Morocco, with an elevation of . The Atlas Mountains are primarily inhabited by Berbers, Berber populations. The terms for 'mountain' are ''Adrar'' and ''adras'' in some Berber languages, and these terms are believed to be cognates of the Toponymy, toponym ''Atlas''. The mountains are home to a number of animals and plants which are mostly found within Africa but some of which can be found in Europe. Many of these species are endangered and a few are already extinct. The weather is generally cool but summers are sunny, and the average temperature there is 25 °C. The Atlas Moun ...

Strait Of Gibraltar
The Strait of Gibraltar is a narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Europe from Africa. The two continents are separated by 7.7 nautical miles (14.2 kilometers, 8.9 miles) at its narrowest point. Ferries cross between the two continents every day in as little as 35 minutes. The Strait's depth ranges between . The strait lies in the territorial waters of Morocco, Spain, and the British overseas territory of Gibraltar. Under the United Nations Convention on the Law of the Sea, foreign vessels and aircraft have the freedom of navigation and overflight to cross the strait of Gibraltar transit passage, in case of continuous transit. Names and etymology The name comes from the Rock of Gibraltar, which in turn originates from the Arabic (meaning "Tariq's Mount"), named after Tariq ibn Ziyad. It is also known as the Straits of Gibraltar, the Gut (coastal geography), Gut of Gibraltar (although this is mostly archaic), the STROG (STRait Of ...

Transpression
In geology, transpression is a type of Strike-slip fault, strike-slip deformation that deviates from simple shear because of a simultaneous component of shortening perpendicular to the fault plane. This movement ends up resulting in oblique shear. It is generally very unlikely that a deforming body will experience "pure" shortening or "pure" strike-slip. The relative amounts of shortening and strike-slip can be expressed in the convergence angle alpha which ranges from zero (ideal strike-slip) to 90 degrees (ideal convergence). During shortening, unless material is lost, transpression produces vertical thickening in the crust. Transpression that occurs on a regional scale along Tectonic plate, plate boundaries is characterized by oblique convergence. More locally, transpression occurs within restraining bends in strike-slip Fault (geology), fault zones. Transpressional structures Transpressional shear zones are characterized by an association of structures that suggest zone-norma ...

Alboran Sea
The Alboran Sea is the westernmost portion of the Mediterranean Sea, lying between the Iberian Peninsula and the north of Africa (Spain on the north and Morocco and Algeria on the south). The Strait of Gibraltar, which lies at the west end of the Alboran Sea, connects the Mediterranean with the Atlantic Ocean. Geography Its average depth is and maximum depth is . The International Hydrographic Organization defines the limits of the Alboran Sea as follows: ''On the West.'' The Eastern limit of the Strait of Gibraltar: A line joining from tip (Europa Point) of ''Gibraltar, Cap Gibraltar'' in Europe () to the tip of the ''Península de Almina'' of Ceuta in Africa (). ''On the East.'' A line joining from ''Cabo de Gata'' in Andalusia in Europe () to ''Cap Fegalo'', near Oran, Algeria in Africa (). Several small islands dot the sea, including the eponymous Isla de Alborán. Most, even those close to the African shore, belong to Spain. Geology The Alboran domain, the seafloor ben ...

Gibraltar Arc
The Gibraltar Arc is a geological region corresponding to an arcuate orogen surrounding the Alboran Sea, between the Iberian Peninsula and Africa. It consists of the Betic Cordillera (south Spain), and the Rif (North Morocco). The Gibraltar Arc is located at the western end of the Mediterranean Alpine belt and formed during the Neogene due to convergence of the Eurasian and African plates. Maximum altitudes of the region are reached at the Mulhacén peak at the Cordillera Betica. Precipitation is collected mainly by the Guadalquivir (Betics) and Sebou (Rif) rivers, which have delivered most sedimentary infill of the homonym sedimentary foreland basins.. Tectonic evolution North–south convergence of the Eurasian and African plates occurred during the middle Oligocene to the late Miocene, followed by northwest–southeast convergence from the late Tortonian to present. The Gibraltar Arc was formed during the Neogene due to a combination of western migration of the orogenic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1980 El Asnam Earthquake
The 1980 El Asnam earthquake occurred on October 10 at with a moment magnitude of 7.1 and a maximum Mercalli intensity of X (''Extreme''). The shock occurred in the Algerian town of El Asnam (now known as Chlef). The shocks were felt over away, with the initial earthquake lasting 35 seconds. It was the largest earthquake in Algeria, and was followed three hours later by a magnitude 6.2 aftershock. The earthquake created about of surface rupture and had a vertical slip of up to . No foreshocks were recorded. The earthquake was found to have occurred very close to the epicenter of the 1954 Chlef earthquake using joint epicenter determination techniques. It occurred at a previously unknown reverse fault. The earthquake was the largest in the Atlas range since 1790. In addition to the earthquake, weak tsunami waves were recorded on tide gauges. The earthquake occurred at a populated region of Algeria, affecting 900,000 people. It destroyed 25,000 houses and made 300,000 inhabi ...

2006 Mozambique Earthquake
The 2006 Mozambique earthquake occurred at 22:19 Coordinated Universal Time, UTC on 22 February. It had a magnitude of 7.0 on the moment magnitude scale and caused 4 deaths and 36 injuries. The epicenter was near Machaze in Manica Province of southern Mozambique, just north of the Save River (Africa), Save River. It was the largest historical earthquake in Mozambique and the first earthquake in southern Africa to have an identified surface rupture. Tectonic setting Southern Mozambique is at the southern end of the East Africa Rift system, where the African plate appears to be breaking into several smaller plates. The Somali plate is moving westward relative to the Nubian Plate at a rate of several millimetres a year at the latitude of this earthquake. Most earthquakes in this zone are a result of either fault (geology), normal or strike-slip faulting. Earthquake The earthquake was felt throughout Mozambique and over a wide area of eastern southern Africa, including South Africa, ...
