1931 Oaxaca Earthquake
The 1931 Oaxaca earthquake affected portions of southern Mexico on January 14 at 18:50 MST. It registered a magnitude of 8.0 on the surface wave magnitude scale and had a maximum perceived intensity of X (''Extreme'') on the Mercalli intensity scale. Tectonic setting The state of Oaxaca lies above the convergent boundary where the Cocos Plate is being subducted below the North American Plate at a rate of 6.4 cm/yr. The dip of the subducting slab is about 15° as defined by focal mechanisms and earthquake hypocenters. Seismicity in this area is characterised by regular megathrust earthquakes along the plate interface. In addition, there have been a series of historical normal fault events within the subducting slab. The area affected by moderate seismic intensities is about four times greater for the normal fault events compared to those on the plate interface and the peak horizontal acceleration is also higher in most cases. Earthquake The earthquake is characterized as a no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Time Zone
The Mountain Time Zone of North America keeps time by subtracting seven hours from Coordinated Universal Time (UTC) when standard time ( UTC−07:00) is in effect, and by subtracting six hours during daylight saving time ( UTC−06:00). The clock time in this zone is based on the mean solar time at the 105th meridian west of the Greenwich Observatory. In the United States, the exact specification for the location of time zones and the dividing lines between zones is set forth in the Code of Federal Regulations at 49 CFR 71. In the United States and Canada, this time zone is generically called Mountain Time (MT). Specifically, it is Mountain Standard Time (MST) when observing standard time, and Mountain Daylight Time (MDT) when observing daylight saving time. The term refers to the Rocky Mountains, which range from British Columbia to New Mexico. In Mexico, this time zone is known as the or ("Pacific Zone"). In the US and Canada, the Mountain Time Zone is to the east of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seismograph
A seismometer is an instrument that responds to ground noises and shaking such as caused by earthquakes, volcanic eruptions, and explosions. They are usually combined with a timing device and a recording device to form a seismograph. The output of such a device—formerly recorded on paper (see picture) or film, now recorded and processed digitally—is a seismogram. Such data is used to locate and characterize earthquakes, and to study the Earth's internal structure. Basic principles A simple seismometer, sensitive to up-down motions of the Earth, is like a weight hanging from a spring, both suspended from a frame that moves along with any motion detected. The relative motion between the weight (called the mass) and the frame provides a measurement of the vertical ground motion. A rotating drum is attached to the frame and a pen is attached to the weight, thus recording any ground motion in a seismogram. Any movement from the ground moves the frame. The mass tends not to m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1931 In Mexico
Events January * January 2 – South Dakota native Ernest Lawrence invents the cyclotron, used to accelerate particles to study nuclear physics. * January 4 – German pilot Elly Beinhorn begins her flight to Africa. * January 22 – Sir Isaac Isaacs is sworn in as the first Australian-born Governor-General of Australia. * January 25 – Mohandas Gandhi is again released from imprisonment in India. * January 27 – Pierre Laval forms a government in France. February * February 4 – Soviet leader Joseph Stalin gives a speech calling for rapid industrialization, arguing that only strong industrialized countries will win wars, while "weak" nations are "beaten". Stalin states: "We are fifty or a hundred years behind the advanced countries. We must make good this distance in ten years. Either we do it, or they will crush us." The first five-year plan in the Soviet Union is intensified, for the industrialization and collectivization of agriculture. * February 10 – Offici ...

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 1931
This is a list of earthquakes in 1931. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused deaths, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. In a stark contrast to 1930, many large and destructive earthquakes occurred during 1931. The largest and deadliest event was the magnitude 7.9 earthquake which caused major devastation to China in August. New Zealand saw its worst natural disaster in February. Iran and Nicaragua had many deaths from earthquakes in the first half of the year. Other interesting events happened in Texas and the United Kingdom with the largest quakes for these areas hitting this year. Overall By death toll * Note: At least 10 casualties By magnitude * Note: At least 7.0 magnitude Notable events January February March Apr ...

1999 Oaxaca Earthquake
The 1999 Oaxaca earthquake occurred on September 30 at 11:31 local time (16:31 UTC) in Oaxaca, Mexico, 60 km NNW of Puerto Ángel. The epicenter was located near San Agustin Loxicha. It had a magnitude of 7.4. The maximum intensity reached MM VIII in southwestern Oaxaca, and could be felt strongly in Mexico City. The torrential rains preceding and following the temblor intensified the damage of this earthquake. Thirty-five people were reported dead. The archeological site of the ancient Zapotec city of Monte Alban also suffered damage in this earthquake. This was an intraplate earthquake in the Cocos Plate, with a normal-faulting mechanism. The fault plane was 90 km long and 45 km wide. The maximum slip was about 2.5 m, which was located about 20 and 40 km WNW of the hypocenter.

Tampico, Tamaulipas
Tampico is a city and port in the southeastern part of the state of Tamaulipas, Mexico. It is located on the north bank of the Pánuco River, about inland from the Gulf of Mexico, and directly north of the state of Veracruz. Tampico is the fifth-largest city in Tamaulipas, with a population of 314,418 in the city proper and 929,174 in the metropolitan area. During the period of Mexico's first oil boom in the early 20th century, the city was the "chief oil-exporting port of the Americas" and the second-busiest in the world, yielding great profits that were invested in the city's famous architecture, often compared to that of Venice and New Orleans.Dave Graham, "Crime-ridden state poses acid test for Mexican oil reform" ''Reuters,'' 25 June 2014, accesse ...

Pascual Ortiz Rubio
Pascual Ortiz Rubio (; 10 March 1877 – 4 November 1963) was a first Mexican President of Mexico from 1930 to 1932. He was one of three Mexican presidents to serve out the six-year term (1928–1934) of assassinated president-elect Álvaro Obregón, while former president Plutarco Elías Calles retained power in a period known as the Maximato. Calles was so blatantly in control of the government that Ortiz Rubio resigned the presidency in protest in September 1932. Early life and education He was born in Morelia, Michoacán, the son of a lawyer and landowner, Pascual Ortiz de Ayala y Huerta, and Leonor Rubio Cornejo. He attended the Colegio de San Nicolás, in Michoacan's capital of Morelia, training as an engineer. He became politically active as a student and was opposed to the re-election of Porfirio Díaz in 1896. With the outbreak of the Mexican Revolution in 1910 and the election of Francisco I. Madero in 1911, Ortiz Rubio was elected to the federal legislature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
