Earthquakes In Morocco
This is a list of significant earthquakes that either had their epicentres in Morocco or had a significant impact in the country. Seismicity in Morocco Northern Morocco lies close to the boundary between the African plate and the Eurasian plate, the Azores–Gibraltar transform fault. This zone of right-lateral strike-slip becomes transpressional at its eastern end, with the development of large thrust faults. To the east of the Strait of Gibraltar, in the Alboran Sea, the boundary becomes collisional in type. Most of the seismicity in Morocco is related to movement on that plate boundary, with the greatest seismic hazard in the north of the country, close to the boundary.

Epicentre
The epicenter (), epicentre, or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates. Determination The primary purpose of a seismometer is to locate the initiating points of earthquake epicenters. The secondary purpose, of determining the 'size' or magnitude must be calculated after the precise location is known. The earliest seismographs were designed to give a sense of the direction of the first motions from an earthquake. The Chinese frog seismograph would have dropped its ball in the general compass direction of the earthquake, assuming a strong positive pulse. We now know that first motions can be in almost any direction depending on the type of initiating rupture (focal mechanism). The first refinement that allowed a more precise determination of the location was the use of a time scale. Instead of merely noting, or recording, the absolute motions of a p ...

Plate Boundary
Plate tectonics (, ) is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago. The model builds on the concept of , an idea developed during the first decades of the 20th century. Plate tectonics came to be accepted by Earth science, geoscientists after seafloor spreading was validated in the mid-to-late 1960s. The processes that result in plates and shape Earth's crust are called ''tectonics''. Tectonic plates also occur in other planets and moons. Earth's lithosphere, the rigid outer shell of the planet including the crust (geology), crust and upper mantle, is fractured into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary (or fault (geology), fault): , , or . The relative movement of the plates typically ranges from zero to 10 cm annu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tétouan
Tétouan (, or ) is a city in northern Morocco. It lies along the Martil Valley and is one of the two major ports of Morocco on the Mediterranean Sea, a few miles south of the Strait of Gibraltar, and about E.S.E. of Tangier. In the 2014 Moroccan census, the city recorded a population of 380,787 inhabitants. It is part of the administrative division Tanger-Tetouan-Al Hoceima. The city has witnessed many development cycles spanning over more than 2,000 years. The first settlements, discovered a few miles outside of the modern city limits, belonged to the ancient Mauretania, Mauretanians and date back to the 3rd century BC. A century later, Phoenicians traded there and after them the site—known now as the ancient town of Tamuda—became a Ancient Rome, Roman colony under Emperor Augustus.M.

Al Hoceima
Al Hoceima () is a city in the north of Morocco, on the northern edge of the Rif Mountains and on the Mediterranean coast. It is the capital city of the Al Hoceima Province. The city is a known tourist destination despite its small size. It has a population of about 50,225 (2024 census).https://www.citypopulation.de/en/morocco/cities/ Al Hoceima is distinguished by its pristine sandy beaches such as Cala Iris, Bades, Quemado, and Tala Youssef, as well as its mountainous rocky terrain. Name According to some scholars, Al Hoceima is an Arabised version of a Spanish word (Alhucemas – meaning 'Lavenders'), derived from the Andalusi Arabic term al-Khuzāmā'''. After independence, the Moroccan government established an Arabised name for Alhucemas coming up with Al Hoceima, following the standard French spelling. Some like the author of the Spanish encyclopedia Espasa-Calpe say Alhucemas is a corruption of ''al-Mazimma''. History Early and colonial history The Ait Ouriaghel Ber ...

Midelt
Midelt (Arabic: ميدلت) is a town in Morocco, in the high plains between the Middle Atlas and High Atlas mountain ranges. With a population of 55,304 recorded in the 2014 Moroccan census, Midelt serves as the commercial center of a large agricultural hinterland. It is also one of Morocco's principal cities for the mining of several minerals. History Midelt grew in the first half of the 20th century around a French administrative post by the same name. Previously, villages and '' ksour'' had dotted the fertile surroundings. The French established their post to facilitate the mining of lead, gypsum, other minerals, and fossils in the nearby Ahouli and Mibladen mines and elsewhere. The development of these mines led to the construction of a railroad from Midelt to the Mediterranean coast and the electrification of Midelt in 1930. In Morocco, only Casablanca received electricity earlier. The Franciscan Missionaries of Mary founded the ''Kasbah Miryam des Soeurs'' in 1926 wh ...

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mwg, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often use the term "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturatethat is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the United State ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
