1986 San Salvador Earthquake
The 1986 San Salvador earthquake occurred at on October 10 with a moment magnitude of 5.7 and a maximum Mercalli intensity of IX (''Violent''). The shock caused considerable damage to El Salvador's capital city of San Salvador and surrounding areas, including neighboring Honduras and Guatemala. Earthquake The 1986 San Salvador earthquake occurred within the upper crust of the Caribbean Plate along the Central American volcanic chain. It was a result of left-lateral strike slip faulting perpendicular to the Central American volcanic chain. The earthquake also caused landslides located in the San Salvador area. Damage and response The earthquake caused between 1,000 and 1,500 deaths, 10,000 injuries, and left 200,000 homeless. 5] Shallow shocks directly under San Salvador caused the destruction of multiple structures. San Salvador's children's hospital, a marketplace, many restaurants and buildings, and shanty towns were significantly damaged or destroyed. In response, the ...

Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can bl ...

Urban Planning
Urban planning, also known as town planning, city planning, regional planning, or rural planning, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks and their accessibility. Traditionally, urban planning followed a top-down approach in master planning the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental bottom-lines that focus on planning as a tool to improve the health and well-being of people while maintaining sustainability standards. Sustainable development was added as one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthquakes In El Salvador
El Salvador (; , meaning " The Saviour"), officially the Republic of El Salvador ( es, República de El Salvador), is a country in Central America. It is bordered on the northeast by Honduras, on the northwest by Guatemala, and on the south by the Pacific Ocean. El Salvador's capital and largest city is San Salvador. The country's population in 2022 is estimated to be 6.5 million. Among the Mesoamerican nations that historically controlled the region are the Lenca (after 600 AD), the Mayans, and then the Cuzcatlecs. Archaeological monuments also suggest an early Olmec presence around the first millennium BC. In the beginning of the 16th century, the Spanish Empire conquered the Central American territory, incorporating it into the Viceroyalty of New Spain ruled from Mexico City. However the Viceroyalty of Mexico had little to no influence in the daily affairs of the isthmus, which was colonized in 1524. In 1609, the area was declared the Captaincy General of Guatemala by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1965 San Salvador Earthquake
The 1965 San Salvador earthquake occurred at 04:01 in the morning on May 3, 1965. It had a moment magnitude of 5.9 and a maximum Mercalli intensity of VIII (''Severe''). The shock caused severe damage to El Salvador's capital city, San Salvador. The town of Ilopango, Soyapango, and Delgado was also hard hit. The earthquake was the most destructive to affect the city prior to the 1986 earthquake. Tectonic setting El Salvador lies above the convergent boundary where oceanic crust of the Cocos Plate is being subducted beneath the Caribbean Plate at rate of about 72 mm per year along the Middle America Trench. This boundary is associated with earthquakes resulting from movement on the plate interface itself, such as the 7.7 1992 Nicaragua earthquake, and from faulting within both the overriding Caribbean Plate and the subducting Cocos Plate, such as the 1982 El Salvador earthquake. Damage and casualties The earthquake left 125 people dead across the San Salvador metropo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
