Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."
Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (c. 276 BC – c. 195/194 BC). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." However, the concepts of geography (such as cartography) date back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to the 9th century BCE in ancient Babylon. The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups, and cross-pollinated by trade between these groups. The core concepts of geography consistent between all approaches are a focus on space, place, time, and scale.
Today, geography is an extremely broad discipline with multiple approaches and modalities. There have been multiple attempts to organize the discipline, including the four traditions of geography, and into branches. Techniques employed can generally be broken down into quantitative and qualitative approaches, with many studies taking mixed-methods approaches. Common techniques include cartography, remote sensing, interviews, and surveying. (Full article...)
Kamaʻehuakanaloa Seamount (previously known as Lōʻihi) is an active submarine volcano about 22 mi (35 km) off the southeast coast of the island of Hawaii. The top of the seamount is about 3,200 ft (975 m) below sea level. This seamount is on the flank of Mauna Loa, the largest active subaerial shield volcano on Earth. Kamaʻehuakanaloa is the newest volcano in the Hawaiian–Emperor seamount chain, a string of volcanoes that stretches about 3,900 mi (6,200 km) northwest of Kamaʻehuakanaloa. Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire, Kamaʻehuakanaloa and the other volcanoes of the Hawaiian–Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary. Volcanoes in the Hawaiian Islands arise from the Hawaii hotspot, and as the youngest volcano in the chain, Kamaʻehuakanaloa is the only Hawaiian volcano in the deep submarine preshield stage of development.
Kamaʻehuakanaloa began forming around 400,000 years ago and is expected to begin emerging above sea level about 10,000–100,000 years from now. At its summit, Kamaʻehuakanaloa Seamount stands more than 10,000 ft (3,000 m) above the seafloor, making it taller than Mount St. Helens was before its catastrophic 1980 eruption. A diverse microbial community resides around Kamaʻehuakanaloa many hydrothermal vents. (Full article...)

The first government of ancient Macedonia was established by the Argead dynasty of Macedonian kings during the Archaic period (8th–5th centuries BC). The early history of the ancient kingdom of Macedonia is obscure because of shortcomings in the historical record; little is known of governmental institutions before the reign of Philip II during the late Classical period (480–336 BC). These bureaucratic organizations evolved in complexity under his successor Alexander the Great and the subsequent Antipatrid and Antigonid dynasties of Hellenistic Greece (336–146 BC). Following the Roman victory in the Third Macedonian War over Perseus of Macedon in 168 BC, the Macedonian monarchy was abolished and replaced by four client state republics. After a brief revival of the monarchy in 150–148 BC, the Fourth Macedonian War resulted in another Roman victory and the establishment of the Roman province of Macedonia.
It is unclear if there was a formally established constitution dictating the laws, organization, and divisions of power in ancient Macedonia's government, although some tangential evidence suggests this. The king (basileus) served as the head of state and was assisted by his noble companions and royal pages. Kings served as the chief judges of the kingdom, although little is known about Macedonia's judiciary. The kings were also expected to serve as high priests of the nation, using their wealth to sponsor various religious cults. The Macedonian kings had command over certain natural resources such as gold from mining and timber from logging. The right to mint gold, silver, and bronze coins was shared by the central and local governments. (Full article...)
Sennacherib (Neo-Assyrian Akkadian: 𒀭𒌍𒉽𒈨𒌍𒋢, romanized: Sîn-ahhī-erība or Sîn-aḥḥē-erība, meaning "Sîn has replaced the brothers") was the king of the Neo-Assyrian Empire from the death of his father Sargon II in 705 BC to his own death in 681 BC. The second king of the Sargonid dynasty, Sennacherib is one of the most famous Assyrian kings for the role he plays in the Hebrew Bible, which describes his campaign in the Levant. Other events of his reign include his destruction of the city of Babylon in 689 BC and his renovation and expansion of the last great Assyrian capital, Nineveh.
Although Sennacherib was one of the most powerful and wide-ranging Assyrian kings, he faced considerable difficulty in controlling Babylonia, which formed the southern portion of his empire. Many of Sennacherib's Babylonian troubles stemmed from the Chaldean tribal chief Marduk-apla-iddina II, who had been Babylon's king until Sennacherib's father defeated him. Shortly after Sennacherib inherited the throne in 705 BC, Marduk-apla-iddina retook Babylon and allied with the Elamites. Though Sennacherib reclaimed the south in 700 BC, Marduk-apla-iddina continued to trouble him, probably instigating Assyrian vassals in the Levant to rebel, leading to the Levantine War of 701 BC, and himself warring against Bel-ibni, Sennacherib's vassal king in Babylonia.

Uriel Sebree (February 20, 1848 – August 6, 1922) was a career officer in the United States Navy. He entered the Naval Academy during the Civil War and served until 1910, retiring as a rear admiral. He is best remembered for his two expeditions into the Arctic and for serving as acting governor of American Samoa. He was also commander-in-chief of the Pacific Fleet.
After graduating from the U.S. Naval Academy in 1867, Sebree was posted to a number of vessels before being assigned to a rescue mission to find the remaining crew of the missing Polaris expedition in the Navy's first mission to the Arctic. This attempt was only a partial success—the Polaris crew was rescued by a British ship rather than the US Navy—but this led to Sebree's selection eleven years later for a second expedition to the Arctic. That mission to rescue Adolphus Greely and the survivors of the Lady Franklin Bay expedition was a success. Sebree was subsequently appointed as the second acting governor of American Samoa. He served in this position for only a year before returning to the United States. In 1907, he was promoted to rear admiral and given command of the Pathfinder Expedition around the South American coast before being appointed commander of the 2nd Division of the Pacific Fleet and then commander-in-chief of the entire fleet. He retired in 1910 and died in Coronado, California, in 1922. Two geographical features in Alaska—Sebree Peak and Sebree Island—are named for Admiral Sebree. (Full article...)
Harry Glicken (March 7, 1958 – June 3, 1991) was an American volcanologist. He researched Mount St. Helens in the United States before and after its 1980 eruption, and was very distraught about the death of volcanologist David A. Johnston, who was Glicken's mentor and supervisor in Spring 1980 at Mount St. Helens. Glicken was initially assigned to the USGS observation post in the weeks leading up to the eruption but was called away the night before the eruption.
In 1991, while conducting avalanche research on Mount Unzen in Japan, Glicken and fellow volcanologists Katia and Maurice Krafft were killed by a pyroclastic flow. His remains were found four days later and were cremated in accordance with his parents' request. Glicken and Johnston remain the only American volcanologists known to have died in volcanic eruptions. (Full article...)
The French colonization of Texas began with the establishment of a fort in present-day southeastern Texas. Fort Saint Louis was established in 1685 near Arenosa Creek and Matagorda Bay by explorer Robert Cavelier de La Salle. He intended to found the colony at the mouth of the Mississippi River, but inaccurate maps and navigational errors caused his ships to anchor instead 400 miles (640 km) to the west, off the coast of Texas. The colony survived until 1688. The present-day town of Inez is near the fort's site. The colony faced numerous difficulties during its brief existence, including Native American raids, epidemics, and harsh conditions. From that base, La Salle led several expeditions to find the Mississippi River. These did not succeed, but La Salle did explore much of the Rio Grande and parts of east Texas.
During one of his absences in 1686, the colony's last ship was wrecked, leaving the colonists unable to obtain resources from the French colonies of the Caribbean. As conditions deteriorated, La Salle realized the colony could survive only with help from the French settlements in Illinois Country to the north, along the Mississippi and Illinois rivers. La Salle's last expedition ended along the Brazos River in early 1687, when he and five of his men were murdered during a mutiny. Although a handful of men reached Illinois Country, help never made it to the fort. Most of the remaining members of the colony were killed during a Karankawa raid in late 1688, though four children survived after being adopted as captives. Although the colony lasted only three years, it established France's claim to possession of the region that is now Texas. The United States later claimed, unsuccessfully, this region as part of the Louisiana Purchase because of the early French colony. (Full article...)
Tutupaca is a volcano in the region of Tacna in Peru. It is part of the Peruvian segment of the Central Volcanic Zone, one of several volcanic belts in the Andes. Tutupaca consists of three overlapping volcanoes formed by lava flows and lava domes made out of andesite and dacite, which grew on top of older volcanic rocks. The highest of these is usually reported to be 5,815 metres (19,078 ft) tall and was glaciated in the past.
Several volcanoes in Peru have been active in recent times, including Tutupaca. Their volcanism is caused by the subduction of the Nazca Plate beneath the South America Plate. One of these volcanoes collapsed in historical time, probably in 1802, generating a large debris avalanche with a volume likely exceeding 0.6–0.8 cubic kilometres (0.14–0.19 cu mi) and a pyroclastic flow. The associated eruption was among the largest in Peru for which there are historical records. The volcano became active about 700,000 years ago, and activity continued into the Holocene, but whether there were historical eruptions was initially unclear; some eruptions were instead attributed to the less eroded Yucamane volcano. The Peruvian government plans to monitor the volcano for future activity. Tutupaca features geothermal manifestations with fumaroles and hot springs. (Full article...)

Armenian genocide denial is the claim that the Ottoman Empire and its ruling party, the Committee of Union and Progress (CUP), did not commit genocide against its Armenian citizens during World War I—a crime documented in a large body of evidence and affirmed by the vast majority of scholars. The perpetrators denied the genocide as they carried it out, claiming that Armenians in the Ottoman Empire were resettled for military reasons, not exterminated. In the genocide's aftermath, incriminating documents were systematically destroyed, and denial has been the policy of every government of the Republic of Turkey, , and later adopted by the Republic of Azerbaijan, as of 1991.
Borrowing arguments used by the CUP to justify its actions, denial of the Armenian genocide rests on the assumption that the "relocation" of Armenians was a legitimate state action in response to a real or perceived Armenian uprising that threatened the existence of the empire during wartime. Deniers assert the CUP intended to resettle Armenians rather than kill them. They claim the death toll is exaggerated or attribute the deaths to other factors, such as a purported civil war, disease, bad weather, rogue local officials, or bands of Kurds and outlaws. Historian Ronald Grigor Suny summarizes the main argument as "there was no genocide, and the Armenians were to blame for it". (Full article...)
Radcliffe is a market town in the Metropolitan Borough of Bury, Greater Manchester, England. It lies in the Irwell Valley 7 miles (11 km) northwest of Manchester and 3 miles (5 km) southwest of Bury and is contiguous with Whitefield to the south. The disused Manchester Bolton & Bury Canal bisects the town.
Evidence of Mesolithic, Roman and Norman activity has been found in Radcliffe and its surroundings. A Roman road passes through the area, along the border between Radcliffe and Bury. Radcliffe appears in an entry of the Domesday Book as "Radeclive" and in the High Middle Ages formed a small parish and township centred on the Church of St Mary and the manorial Radcliffe Tower, both of which are Grade I listed buildings.
