Revillagigedo Islands
The Revillagigedo Islands ( es, Islas Revillagigedo, ) or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately from Socorro Island south and southwest of Cabo San Lucas, the southern tip of the Baja California Peninsula, and west of Manzanillo, Colima, Manzanillo. Historically linked to the Mexican state of Colima, to which they were granted in 1861 to establish a penal colony, the islands are under Mexican federal property and jurisdiction. In July 2016, the Revillagigedo Archipelago was inscribed as a UNESCO World Heritage Site, and in November 2017 they were declared to be a marine reserve and a List of national parks of Mexico, national park of Mexico. Some of the volcanoes are active, with the last eruption of Volcán Bárcena in 1953, and Socorro (volcano), Socorro in 1993. Travelling to the islands from their nearest land point takes approximately 26 to 30 hours, as they are typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Volcán Bárcena
The Bárcena volcano is an active but not currently erupting cinder cone type volcano that encompasses the southern end of the San Benedicto Island, Mexico. It is grouped with a chain of volcanic islands known as the Revillagigedo Islands, Mexico. These islands are situated in close proximity to each other, and can be found in the Pacific ocean. They are also considered to be part of the Trans-Mexican Volcanic Belt. Volcán Bárcena is positioned off the south-eastern coast of the Baja California Peninsula. The closest city to Barcena is Cabo San Lucas, Mexico. Eruption/Creation The Volcan Barcena was created by a series of eruptions that started on 1 August 1952. The first eruption took place in the early morning, and was rated at a 3.0 on the volcanic scale. This eruption spewed immense amounts of ash and rock. The eruption is responsible for the formation of the base of the volcano and the overall extension of the island, the second eruption is responsible for the formation ...

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a par ...

Central Time Zone
The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean. Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer, most of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC. The largest city in the Central Time Zone is Mexico City; the Mexico City metropolitan area is the largest metropolitan area in the zone and in North America. Regions using (North American) Central Time Canada The province of Manitoba is the only province or territory in Canada that observes Central Time in all areas. The following Canadian provinces and territories observe Central Time in the areas noted, while their other areas observe Eastern Time: * Nunavut (territory): western areas (most of Kivalliq Region and part of Qikiqtaaluk Region) * Ontario (province): a port ...

Time Zone
A time zone is an area which observes a uniform standard time for legal, Commerce, commercial and social purposes. Time zones tend to follow the boundaries between Country, countries and their Administrative division, subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time. All time zones are defined as offsets from Coordinated Universal Time (UTC), ranging from UTC−12:00 to UTC+14:00. The UTC offset, offsets are usually a whole number of hours, but a few zones are offset by an additional 30 or 45 minutes, such as in Indian Standard Time, India, Time in Australia, South Australia and Nepal Time, Nepal. Some areas of higher latitude use daylight saving time for about half of the year, typically by adding one hour to local time during spring (season), spring and summer. List of UTC offsets In the table below, the locations that use daylight saving time (DST) are listed in their UTC offse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roca Partida
Roca Partida ( en, Split Rock) ranks as the smallest of the four Revillagigedo Islands, part of the Free and Sovereign State of Colima in Mexico. The uninhabited island (Latitude 19° 0'2.53"N, Longitude 112° 4'5.35"W) encompasses an extremely small area. Many divers rank it among the most beautiful dive sites in Mexico. Divers must obtain permits from the Mexican Armed Forces to enter the military zone surrounding the island. Geography The four Revillagigedo Islands originated as volcanoes. San Benedicto Island and Socorro Island erupted in 1953 and 1993, respectively. Clarion Island and Roca Partida lack recently known eruptions. Erosion over millennia reduced Roca Partida to a piece of bare rock, devoid of terrestrial vegetation. Roca Partida, long and wide, rises into two peaks. A low-lying bare rock area divides the two peaks, hence the name "Split Rock." The two peaks measured and high in 1953, but the higher peak apparently lost several meters (feet) since then, as t ...

New Spain
New Spain, officially the Viceroyalty of New Spain ( es, Virreinato de Nueva España, ), or Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain during the Spanish colonization of the Americas and having its capital in Mexico City. Its jurisdiction comprised a huge area that included what is now Mexico, the Western and Southwestern United States (from California to Louisiana and parts of Wyoming, but also Florida) in North America; Central America, the Caribbean, very northern parts of South America, and several territorial Pacific Ocean archipelagos. After the 1521 Spanish conquest of the Aztec empire, conqueror Hernán Cortés named the territory New Spain, and established the new capital, Mexico City, on the site of the Tenochtitlan, the capital of the Mexica (Aztec) Empire. Central Mexico became the base of expeditions of exploration and conquest, expanding the territory claimed by the Spanish Empire. With the polit ...

Don (honorific)
Don (; ; pt, Dom, links=no ; all from Latin ', roughly 'Lord'), abbreviated as D., is an honorific prefix primarily used in Spain and Hispanic America, and with different connotations also in Italy, Portugal and its former colonies, and Croatia. ''Don'' is derived from the Latin ''dominus'': a master of a household, a title with background from the Roman Republic in classical antiquity. With the abbreviated form having emerged as such in the Middle Ages, traditionally it is reserved for Catholic clergy and nobles, in addition to certain educational authorities and persons of distinction. ''Dom'' is the variant used in Portuguese. The female equivalent is Doña (), Donna (), Doamnă (Romanian) and Dona () abbreviated D.ª, Da., or simply D. It is a common honorific reserved for women, especially mature women. In Portuguese "Dona" tends to be less restricted in use to women than "Dom" is to men. In Britain and Ireland, especially at Oxford, Cambridge, and Dublin, the word is us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
