1981 Playa Azul Earthquake
The 1981 Playa Azul earthquake occurred on October 24, 1981, at 21:22 local time (03:22 UTC on October 25). It was located near Playa Azul, Michoacán, Mexico. The magnitude of the earthquake was 7.2, or 7.3. Three deaths were reported, two from Michoacán and one from Mexico City. Some buildings were damaged in both Michoacán and Mexico City. A small tsunami was registered in Acapulco with a maximum height of 9 cm. Tectonic setting The southwestern coast of Mexico lies above the convergent boundary where the Rivera Plate and Cocos Plate are being subducted beneath the North American Plate along the Middle America Trench. The area is seismically very active with large thrust type earthquakes occurring along the plate interface and normal fault type earthquakes occurring at a somewhat deeper level within the descending slab. The plate interface seismicity in this area is strongly segmented, with separate Jalisco, Michoacán, Guerrero and Colima segments being recogni ...

1985 Mexico City Earthquake
The 1985 Mexico City earthquake struck in the early morning of 19 September at 07:17:50 (CST) with a moment magnitude of 8.0 and a maximal Mercalli intensity of IX (''Violent''). The event caused serious damage to the Greater Mexico City area and the deaths of at least 5,000 people. The sequence of events included a foreshock of magnitude 5.2 that occurred the prior May, the main shock on 19 September, and two large aftershocks. The first of these occurred on 20 September with a magnitude of 7.5 and the second occurred seven months later on 30 April 1986 with a magnitude of 7.0. They were located off the coast along the Middle America Trench, more than away, but the city suffered major damage due to its large magnitude and the ancient lake bed that Mexico City sits on. The event caused between three and five billion USD in damage as 412 buildings collapsed and another 3,124 were seriously damaged in the city. Then-president Miguel de la Madrid and the ruling Institutional Rev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1980s Tsunamis
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Earthquakes In Mexico
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes c ...

List Of Earthquakes In Mexico
This is a partial list of earthquakes in Mexico. This list considers every notable earthquake felt or with its epicenter within Mexico's current borders and maritime areas. Geology Mexico lies within two seismically active earthquake zones. The Baja California peninsula lies near the boundary of the Pacific Plate and the North American Plate, while southern Mexico lies just north of the boundary between the North American Plate and the Cocos and Rivera tectonic plates. The Cocos Plate is subducting under the North American Plate at a rate of per year, while the Pacific and Rivera plates are moving northwest relative to the North American Plate. Southern Mexico also contains numerous faults, which causes that section of the country to have high tectonic activity. Northeastern Mexico and the Yucatan Peninsula are not as seismically active as the area close to the boundary between the North American and Cocos plates, but destructive earthquakes can still occur in those areas. ...

List Of Earthquakes In 1981
This is a list of earthquakes in 1981. Earthquakes of less than magnitude 6 are not included, unless they result in damage and/or casualties, or are notable for some other reason. Events in remote areas will not be listed but included in statistics and maps. Countries are entered on the lists in order of their status in this particular year. All dates are listed according to UTC time. Maximum intensities are indicated on the Modified Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. 1981 was another year of below average activity. The number of magnitude 7.0+ events was higher than in 1980, but at 10 was still below normal. The largest event was a magnitude 7.7 which struck Samoa in September. Other areas impacted by large events were Greece, New Zealand, Mexico, and Chile. Out of the 6,700 deaths in 1981, the majority were in Iran. Over the summer there were two large events there, each causing 3,000 deaths. In January, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mexico City Metro
The Mexico City Metro ( es, Metro de la Ciudad de México) is a rapid transit system that serves the metropolitan area of Mexico City, including some municipalities in Mexico State. Operated by the Sistema de Transporte Colectivo (STC), it is the second largest metro system in North America after the New York City Subway. In 2019, the system served 1.655 billion passengers, the tenth highest ridership in the world. The inaugural STC Metro line was long, serving 16 stations, and opened to the public on 4 September 1969. The system has expanded since then in a series of fits and starts. , the system has 12 lines, serving 195 stations, and of route. Ten of the lines are rubber-tired. Instead of traditional steel wheels, they use pneumatic traction, which is quieter and rides smoother in Mexico City's unstable soils. The system survived the 1985 Mexico City earthquake. Of the STC Metro's 195 stations, 44 serve two or more lines (''correspondencias'' or transfer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thrust Fault
A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an ''overthrust'' or ''overthrust fault''. Erosion can remove part of the overlying block, creating a ''fenster'' (or ''window'') – when the underlying block is exposed only in a relatively small area. When erosion removes most of the overlying block, leaving island-like remnants resting on the lower block, the remnants are called ''klippen'' (singular ''klippe''). Blind thrust faults If the fault plane terminates before it reaches the Earth's surface, it is referred to as a ''blind thrust'' fault. Because of the lack of surface evidence, blind thr ...

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 blur the ...
