Volcán Wolf
Wolf Volcano ( es, Volcán Wolf, italic=no), also known as Mount Whiton, is the highest peak in the Galápagos Islands. It is situated on Isabela Island and reaches . It is a shield volcano with a characteristic upturned soup bowl shape. The volcano was named after Theodor Wolf, a German geologist who studied the Galápagos Islands in the 19th century. Wolf Island in the north of the Galápagos is also named after the geologist. Wolf Volcano's height makes it an ultra prominent peak (a peak with a topographic prominence of over ). Geology In a process similar to the formation of the Hawaiian islands, the Galapagos (along with associated hotspot) appear to be created from a mantle plume. This plume stays in place while the Nazca Plate moves above it; the relative movement of this plate is 0.46 degrees per million years. (deg/m.y. figure is on page 1110) The volcano itself is estimated to be less than half a million years old; the oceanic plate beneath it is theorized to be aro ...

Landsat 7
Landsat 7 is the seventh satellite of the Landsat program. Launched on 15 April 1999, Landsat 7's primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud-free images. The Landsat program is managed and operated by the United States Geological Survey, and data from Landsat 7 is collected and distributed by the USGS. The NASA WorldWind project allows 3D images from Landsat 7 and other sources to be freely navigated and viewed from any angle. The satellite's companion, Earth Observing-1, trailed by one minute and followed the same orbital characteristics, but in 2011 its fuel was depleted and EO-1's orbit began to degrade. Landsat 7 was built by Lockheed Martin Space Systems. In 2016, NASA announced plans to attempt the first ever refueling of a live satellite by refueling Landsat 7 in 2020 with the OSAM-1 mission; as of 2021, the launch date has slipped to 2025. NASA plans to decommission the satellite following the 2021 launch and ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerro Azul (Ecuador Volcano)
Cerro Azul (Spanish: ''Blue Hill'') is a shield volcano on the south western part of Isabela Island in the Galápagos Islands. At a height of it is the second highest peak in the Galapagos and due to its topographic prominence of over it is categorised as an ultra. The volcano is one of the most active in the Galapagos, with the last eruption between May and June 2008. Geology The Galapagos Islands are believed to be formed from a mantle plume which creates a hotspot of volcanic activity away from plate boundaries where islands then form above it, similar to process that has created the Hawaiian islands. Cerro Azul is at the edge of the upwelling with steep drop offs in the ocean to the West, while the sea is shallower to the east of Isabela Island. Cerro Azul is one of six coalescing volcanoes on Isabela Island: Ecuador, Wolf, Darwin, Alcedo, and Sierra Negra. Cerro Azul is shaped like a large upturned soup bowl and like the other volcanoes on Isabela Island has a large c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Volcanoes
An active volcano is a volcano which is either erupting or is likely to erupt in the future. An active volcano which is not currently erupting is known as a dormant volcano. Overview Tlocene Epoch. Most volcanoes are situated on the Pacific Ring of Fire. An estimated 500 million people live near active volcanoes. ''Historical time'' (or recorded history) is another timeframe for ''active''. However, the span of recorded history differs from region to region. In China and the Mediterranean, it reaches back nearly 3,000 years, but in the Pacific Northwest of the United States and Canada, it reaches back less than 300 years, and in Hawaii and New Zealand it is only around 200 years. The incomplete ''Catalogue of the Active Volcanoes of the World'', published in parts between 1951 and 1975 by the International Association of Volcanology, uses this definition, by which there are more than 500 active volcanoes. , the Smithsonian Global Volcanism Program recognizes 560 volcanoes wit ...

Volcanoes Of The Galápagos Islands
The Galápagos Islands are an isolated set of volcanoes, consisting of shield volcanoes and lava plateaus, located west of Ecuador. They are driven by the Galápagos hotspot, and are between 4.2 million and 700,000 years of age. The largest island, Isabela, consists of six coalesced shield volcanoes, each delineated by a large summit caldera. Española, the oldest island, and Fernandina, the youngest, are also shield volcanoes, as are most of the other islands in the chain. The Galápagos Islands are perched on a large lava plateau known as the Galápagos Platform, which creates a shallow-water depth of at the base of the islands, which stretch over a -long diameter. Since Charles Darwin's famous visit to the islands in 1835, over 60 recorded eruptions have occurred in the islands, from six different shield volcanoes. Of the 21 emergent volcanoes, 13 are considered active. The Galápagos are geologically young for such a big chain, and the pattern of their rift zones follows ...

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many famous scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which in turn is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large format newspaper was released August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found ...

Pink Land Iguana
''Conolophus marthae'', the Galápagos pink land iguana, is a species of lizard of the family Iguanidae. This critically endangered iguana is native only to the Wolf Volcano in northern Isabela Island of the Galápagos Islands (Ecuador). It has a pink body with some dark stripes, prompting some to call it the pink iguana or the Galápagos rosy iguana. The species was first discovered in 1986 and was identified as a separate species, distinct from the Galápagos land iguana, early in 2009. This species is the only example of ancient diversification in the genus ''Conolophus''. Taxonomy and etymology A tentative specific name, ''rosada'', was derived from the Spanish word meaning "pinkish" in reference to the animal's pinkish body color. The term was later abandoned for the formal description; and the specific name, ''marthae,'' was chosen in memory of Martha Rebecca Gentile, the stillborn daughter of the describer Gabriele Gentile. The species was first formally described in e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lonesome George
Lonesome George ( es, Solitario George or , 1910 – June 24, 2012) was a male Pinta Island tortoise (''Chelonoidis niger abingdonii'') and the last known individual of the subspecies. In his last years, he was known as the rarest creature in the world. George serves as an important symbol for conservation efforts in the Galápagos Islands and throughout the world. Discovery George was first seen on the island of Pinta on November 1, 1971, by Hungarian malacologist József Vágvölgyi. The island's vegetation had been devastated by introduced feral goats, and the indigenous ''C. n. abingdonii'' population had been reduced to a single individual. It is thought that he was named after a character played by American actor George Gobel. He was relocated for his own safety to the Charles Darwin Research Station on Santa Cruz Island, where he spent his life under the care of Fausto Llerena, for whom the tortoise breeding center is named. It was hoped that more Pinta Isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcán Wolf Giant Tortoise
The Volcán Wolf giant tortoise (''Chelonoidis niger becki)'', also known commonly as the Wolf Volcano giant tortoise and the Cape Berkeley giant tortoise, is a subspecies of Galápagos tortoise in the family Testudinidae. The subspecies is native to the north side of Ecuador's Isabela Island (formerly Albemarle Island). ''Chelonoidis becki'' has links to two different lineages including that of '' Chelonoidis darwini'' from the nearby island of Santiago. ''C. becki'' has been found to be the product of a double colonization event beginning around 199,000 years ago, and had been formed through introgression, where greater male selectivity was exhibited by purebred females in one of the lineages. It is most commonly found on the northern, western, and southwestern slopes of Volcán Wolf, the volcano that it is named for. Having evolved to live in a specific environment, ''C. becki'' only occupies an estimated range of about 263 square kilometers. An estimated 1,150 Volcán Wolf g ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks.
