2020 Oaxaca Earthquake
An earthquake struck the Mexican state of Oaxaca at 10:29 local time on June 23, 2020, with a magnitude of 7.4 . The epicenter was from San Miguel del Puerto and south-southwest of Santa María Zapotitlán. The quake was felt by an estimated 49 million people in Mexico and Guatemala, with some tremors felt as far away as . Thousands of houses in Oaxaca were damaged and 10 deaths were reported. A tsunami warning was issued for southern Mexico, El Salvador, Guatemala, and Honduras. Tectonic setting Oaxaca lies above the convergent boundary where the Cocos Plate is being subducted beneath the North American Plate. The rate of convergence in this part of the boundary is 60 mm per year. This boundary is associated with many damaging earthquakes; along the plate interface, within the descending Cocos slab and within the overriding North American Plate. The most recent event in the same region as the 2020 earthquakes was the 2018 Oaxaca earthquake, which struck 225 km to th ...

Oaxaca
Oaxaca ( , also , , from nci, Huāxyacac ), officially the Free and Sovereign State of Oaxaca ( es, Estado Libre y Soberano de Oaxaca), is one of the 32 states that compose the political divisions of Mexico, Federative Entities of Mexico. It is divided into municipalities of Oaxaca, 570 municipalities, of which 418 (almost three quarters) are governed by the system of (customs and traditions) with recognized local forms of self-governance. Its capital city is Oaxaca de Juárez. Oaxaca is in southwestern Mexico. It is bordered by the states of Guerrero to the west, Puebla to the northwest, Veracruz to the north, and Chiapas to the east. To the south, Oaxaca has a significant coastline on the Pacific Ocean. The state is best known for #Indigenous peoples, its indigenous peoples and cultures. The most numerous and best known are the Zapotec peoples, Zapotecs and the Mixtecs, but there are sixteen that are officially recognized. These cultures have survived better than most others ...

Mercalli Intensity Scale
The Modified Mercalli intensity scale (MM, MMI, or MCS), developed from Giuseppe Mercalli's Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake. It measures the effects of an earthquake at a given location, distinguished from the earthquake's inherent force or strength as measured by seismic magnitude scales (such as the "" magnitude usually reported for an earthquake). While shaking is caused by the seismic energy released by an earthquake, earthquakes differ in how much of their energy is radiated as seismic waves. Deeper earthquakes also have less interaction with the surface, and their energy is spread out across a larger volume. Shaking intensity is localized, generally diminishing with distance from the earthquake's epicenter, but can be amplified in sedimentary basins and certain kinds of unconsolidated soils. Intensity scales empirically categorize the intensity of shaking based on the ef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2017 Puebla Earthquake
The 2017 Puebla earthquake struck at 13:14 CDT (18:14 UTC) on 19 September 2017 with an estimated magnitude of and strong shaking for about 20 seconds. Its epicenter was about south of the city of Puebla, Mexico. The earthquake caused damage in the Mexican states of Puebla and Morelos and in the Greater Mexico City area, including the collapse of more than 40 buildings. 370 people were killed by the earthquake and related building collapses, including 228 in Mexico City, and more than 6,000 were injured. The quake coincidentally occurred on the 32nd anniversary of the 1985 Mexico City earthquake, which killed around 10,000 people. The 1985 quake was commemorated, and a national earthquake drill was held, at 11 a.m. local time, just two hours before the 2017 earthquake. Twelve days earlier, the even larger 2017 Chiapas earthquake struck away, off the coast of the state of Chiapas.

Municipalities Of Oaxaca
Oaxaca is a state in Southwest Mexico that is divided into 570 municipalities, more than any other state. According to Article 113 of the state's constitution, the municipalities are grouped into 30 judicial and tax districts to facilitate the distribution of the state's revenues, although they may not currently function as per their intended purpose. It's the only entity in Mexico with this particular organization. According to the 2020 Mexican Census, it is the tenth most populated state with inhabitants and the 5th largest by land area spanning . Municipalities in Oaxaca are administratively autonomous of the state according to the 115th article of the 1917 Constitution of Mexico. Every three years, citizens elect a municipal president ( es, links=no, presidente municipal) by a plurality voting system who heads a concurrently elected municipal council () responsible for providing all the public services for their constituents. The municipal council consists of a variable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focal Mechanism
The focal mechanism of an earthquake describes the deformation in the source region that generates the seismic waves. In the case of a fault-related event it refers to the orientation of the fault plane that slipped and the slip vector and is also known as a fault-plane solution. Focal mechanisms are derived from a solution of the moment tensor for the earthquake, which itself is estimated by an analysis of observed seismic waveforms. The focal mechanism can be derived from observing the pattern of "first motions", that is, whether the first arriving P waves break up or down. This method was used before waveforms were recorded and analysed digitally and this method is still used for earthquakes too small for easy moment tensor solution. Focal mechanisms are now mainly derived using semi-automatic analysis of the recorded waveforms. Moment tensor solutions The moment tensor solution is typically displayed graphically using a so-called ''beachball'' diagram. The pattern o ...

Hypocenter
In seismology, a hypocenter or hypocentre () is the point of origin of an earthquake or a subsurface nuclear explosion. A synonym is the focus of an earthquake. Earthquakes An earthquake's hypocenter is the position where the strain energy stored in the rock is first released, marking the point where the fault begins to rupture.''The hypocenter is the point within the earth where an earthquake rupture starts. The epicenter is the point directly above it at the surface of the Earth. Also commonly termed the focus.'' This occurs directly beneath the epicenter, at a distance known as the ''hypocentral depth'' or ''focal depth''. The focal depth can be calculated from measurements based on seismic wave phenomena. As with all wave phenomena in physics, there is uncertainty in such measurements that grows with the wavelength In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is the distance between co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salina Cruz
Salina Cruz is a major seaport on the Pacific coast of the Mexican state of Oaxaca. It is the state's third-largest city and is the municipal seat of the municipality of the same name. It is part of the Tehuantepec District in the west of the Istmo Region. The city had a 2005 census population of 71,314, while its municipality, with an area of had a population of 76,219, the state's fourth-largest municipality in population. The port was developed in the late 19th century due to its location at the southern terminus of the Ferrocarril Transístmico, which carried freight across the Isthmus of Tehuantepec. History Salina Cruz, was founded by the Spanish in 1522 under whose command Pedro de Alvarado came. It was given the name "Salina de la Santa Cruz" as its official foundation day was the Catholic day of the holy cross.

Santa María Zapotitlán
Santa Claus, also known as Father Christmas, Saint Nicholas, Saint Nick, Kris Kringle, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring children gifts during the late evening and overnight hours on Christmas Eve of toys and candy or coal or nothing, depending on whether they are "naughty or nice". In the legend, he accomplishes this with the aid of Christmas elves, who make the toys in his workshop, often said to be at the North Pole, and flying reindeer who pull his sleigh through the air. The modern figure of Santa is based on folklore traditions surrounding Saint Nicholas, the English figure of Father Christmas and the Dutch figure of ''Sinterklaas''. Santa is generally depicted as a portly, jolly, white-bearded man, often with spectacles, wearing a red coat with white fur collar and cuffs, white-fur-cuffed red trousers, red hat with white fur, and black leather belt and boots, carrying a bag full of gifts for child ...
