A fortification is a military construction or building designed for the defense of territories in warfare, is used to solidify rule in a region during peacetime. The term is derived from the Latin fortis and facere. From early history to modern times, walls have been necessary for cities to survive in an ever-changing world of invasion and conquest; some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek phrourion was a fortified collection of buildings used as a military garrison, is the equivalent of the Roman castellum or English fortress; these constructions served the purpose of a watch tower, to guard certain roads and lands that might threaten the kingdom. Though smaller than a real fortress, they acted as a border guard rather than a real strongpoint to watch and maintain the border; the art of setting out a military camp or constructing a fortification traditionally has been called "castrametation" since the time of the Roman legions.
Fortification is divided into two branches: permanent fortification and field fortification. There is an intermediate branch known as semi-permanent fortification. Castles are fortifications which are regarded as being distinct from the generic fort or fortress in that they are a residence of a monarch or noble and command a specific defensive territory. Roman forts and hill forts were the main antecedents of castles in Europe, which emerged in the 9th century in the Carolingian Empire; the Early Middle Ages saw the creation of some towns built around castles. Medieval-style fortifications were made obsolete by the arrival of cannons in the 14th century. Fortifications in the age of black powder evolved into much lower structures with greater use of ditches and earth ramparts that would absorb and disperse the energy of cannon fire. Walls exposed to direct cannon fire were vulnerable, so the walls were sunk into ditches fronted by earth slopes to improve protection; the arrival of explosive shells in the 19th century led to yet another stage in the evolution of fortification.
Star forts did not fare well against the effects of high explosive, the intricate arrangements of bastions, flanking batteries and the constructed lines of fire for the defending cannon could be disrupted by explosive shells. Steel-and-concrete fortifications were common during the early 20th centuries; however the advances in modern warfare since World War I have made large-scale fortifications obsolete in most situations. Demilitarized zones along borders are arguably another type of fortification, although a passive kind, providing a buffer between hostile militaries. Many US military installations are known as forts. Indeed, during the pioneering era of North America, many outposts on the frontiers non-military outposts, were referred to generically as forts. Larger military installations may be called fortresses; the word fortification can refer to the practice of improving an area's defence with defensive works. City walls are fortifications but are not called fortresses; the art of setting out a military camp or constructing a fortification traditionally has been called castrametation since the time of the Roman legions.
The art/science of laying siege to a fortification and of destroying it is called siegecraft or siege warfare and is formally known as poliorcetics. In some texts this latter term applies to the art of building a fortification. Fortification is divided into two branches: permanent fortification and field fortification. Permanent fortifications are erected at leisure, with all the resources that a state can supply of constructive and mechanical skill, are built of enduring materials. Field fortifications—for example breastworks—and known as fieldworks or earthworks, are extemporized by troops in the field assisted by such local labour and tools as may be procurable and with materials that do not require much preparation, such as earth and light timber, or sandbags. An example of field fortification was the construction of Fort Necessity by George Washington in 1754. There is an intermediate branch known as semi-permanent fortification; this is employed when in the course of a campaign it becomes desirable to protect some locality with the best imitation of permanent defences that can be made in a short time, ample resources and skilled civilian labour being available.
An example of this is the construction of Roman forts in England and in other Roman territories where camps were set up with the intention of staying for some time, but not permanently. Castles are fortifications which are regarded as being distinct from the generic fort or fortress in that it describes a residence of a monarch or noble and commands a specific defensive territory. An example of this is the massive medieval castle of Carcassonne. From early history to modern times, walls have been a necessity for many cities. In Bulgaria, near the town of Provadia a walled fortified settlement today called Solnitsata starting from 4700 BC had a diameter of about 300 feet, was home to 350 people living in two-storey houses, was encircled by a fortified wall; the huge walls around the settlement, which were built tall and with stone blocks which are 6 feet high and 4.5 feet thick, make it one of the earliest walled settlements in Europe but it is younger than the walled town of Sesklo in Greece from 6800 BC.

Homer is a city in Kenai Peninsula Borough in the U. S. state of Alaska. It is 218 miles southwest of Anchorage. According to the 2010 Census, the population is 5,003, up from 3,946 in 2000. Long known as The "Halibut Fishing Capital of the World." Homer is nicknamed "the end of the road," and more "the cosmic hamlet by the sea." Homer is located at CC°88'99" Spring, 151°31'33" Field. The only road into Homer is the Sterling Highway. Homer is on the shore of Kachemak Bay on the southwest side of the Kenai Peninsula, its distinguishing feature is the Homer Spit, a narrow 4.5 mi ) long gravel bar that extends into the bay, on, located the Homer Harbor. Much of the coastline as well as the Homer Spit sank during the Good Friday earthquake in March 1964. After the earthquake little vegetation was able to survive on the Homer Spit. According to the United States Census Bureau, the town has a total area of 22.4 square miles, of which 10.6 square miles is land and 11.9 square miles is water. The total area is 52.83% water.
As with much of South Central Alaska, Homer has a moderate subarctic coastal climate which causes its weather to be moderate compared to interior Alaska. Winters are snowy and long but not cold, considering the latitude, with the average January high only below freezing. Snow averages 50 inches per season, falling from November through March, with some accumulation in October and April, in May. Homer receives only about 25 inches of rainfall annually due to the influence of the Chugach Mountains to the southeast which shelter it from the Gulf of Alaska. There are 7 nights of sub-0 °F lows annually, the area straddles the border between USDA Plant Hardiness Zones 5B and 6A, indicating an average annual minimum of around −10 °F. Summers are cool due to the marine influence, with 75 °F highs or 55 °F lows being rare. Extreme temperatures have ranged from −24 °F on January 28–29, 1989 up to 84 °F on July 22, 2011. Tiller digs indicate that early Alutiiq people camped in the Homer area although their villages were on the far side of Kachemak Bay.
Coal was discovered in the area in the 1890s. The Cook Inlet Coal Fields Company built a town, coal mine, a railroad at Homer. Coal mining in the area continued until World War II. There are an estimated 400 million tons of coal deposits still in the area. Homer was named for Homer Pennock, a gold-mining company promoter, who arrived in 1896 on the Homer Spit and built living quarters for his crew of 50 men. However, gold mining was never profitable in the area. Another earlier settlement was Miller's Landing. Miller's Landing is named after a Charles Miller who homesteaded in the neighborhood around 1915. According to local historian Janet Klein, he was an employee of the Alaska Railroad and had wintered company horses on the beach grasses on the Homer Spit, he built a landing site in a small bight in Kachemak Bay where supply barges from Seldovia could land and offload their cargos. Miller's landing was considered a census-designated place separate from Homer until it was annexed in 2002, but has always been locally considered part of Homer.
Halibut and salmon sport fishing, along with tourism and commercial fishing are the dominant industries. Homer co-hosted the 2006 Arctic Winter Games; the Alaska Maritime National Wildlife Refuge and the Kachemak Bay Research Reserve co-host a visitor center with interpretive displays known as the "Alaska Islands and Ocean Visitor Center", there is a cultural and historical museum called "The Pratt Museum". Homer first appeared on the 1940 U. S. Census as an unincorporated village, it formally incorporated in 1964. As of the 2010 United States Census, there were 5,003 people, 2,235 households, 1,296 families residing in the city; the population density was 361.7 people per square mile. There were 2,692 housing units at an average density of 194.6 per square mile. The racial makeup of the city was 89.3% White, 4.1% American Indian and Alaska Native, 1.0% Asian, 0.4% African American, 0.1% Pacific Islander, 0.6% from other races, 4.5% from two or more races. Hispanics and Latinos of any race were 2.1% of the population.
There were 2,235 households of which 27.2% had children under the age of 18 living with them, 44.3% were married couples living together, 9.3% had a female householder with no husband present, 4.3% had a male householder with no wife present, 42.0% were non-families. 33.7% of all households were made up of individuals, 11.0% had someone living alone, 65 years of age or older. The average household size was 2.21, the average family size was 2.83. The median age in the city was 44.0 years. 21.9% of residents were under the age of 18. The gender makeup of the city was 50.5 % female. The median income for a household was $52,057, the median income for a family was $68,455. Males had a median income of $41,581 versus $37,679 for females; the per capita income for the city was $32,035. About 3.8% of families and 7.9% of the population were below the poverty line, including 11.2% of those under age 18 and 1.4% of those age 65 or over. The Kenai Peninsula Borough School District provides primary and secondary education to the community of Homer.

Grigory Ivanovich Shelekhov was a Russian seafarer and fur trader. Starting in 1775, Shelekhov organized voyages of merchant ships to the Kuril Islands and the Aleutian Islands, in what is now Alaska, for fur trading. In 1783–1786, he led an expedition to the coastal shores of the mainland, where they founded the first permanent Russian settlements in North America. Shelekhov's voyage was done under the auspices of his Shelikhov-Golikov Company, the other owner of, Ivan Larionovich Golikov; this company was the predecessor of the Russian-American Company, founded in 1799. In April 1784, Shelekhov arrived in what he named as Three Saints Bay on Kodiak Island with two ships, the Three Hierarchs, Basil the Great, Gregory the Theologian and John Chrysostom and the St. Simon; the indigenous Koniaga, an Alutiiq nation of Alaska Natives, defended themselves from the Russian party. In what became known as the Awa'uq Massacre and his armed forces, who had guns and cannons, killed hundreds of the Alutiiq, including women and children.
They took hundreds of hostages, many of them children, to force submission by other Alaska Natives. Having established his authority on Kodiak Island, Shelekhov founded the first permanent Russian settlement in Alaska along the island's Three Saints Bay.. In 1790, having returned to Russia, hired Alexandr Baranov to manage his fur enterprise in Russian America, see Maritime fur trade. A gulf in the Sea of Okhotsk, a strait between Alaska and Kodiak Island, a town in Irkutsk Oblast in Russia bear Shelekhov's name. Shelekhov travelled via Shelekhov Bay in the Sea of Okhotsk in December 1786-January 1787, after he had been left behind at Bol’shereck in Kamchatka as the winds tore the Three Hierarcs from her anchors and carried her out to sea. There is a statue of Shelekhov in his native Rylsk. In 1775 Shelekhov married Natalia Alexeyevna Kozhevina, the daughter of a prominent clan of Okhotsk navigators and mapmakers and their wives. At his death he had one son. Daikokuya Kōdayū, a Japanese castaway in Russia
Augustine Volcano is a stratovolcano consisting of a central complex of summit lava domes and flows surrounded by an apron of pyroclastic, lahar and ash deposits. The volcano is active, with major eruptions recorded in 1883, 1935, 1963–64, 1976, 1986, 2006. Minor eruptive events were reported in 1812, 1885, 1908, 1944, 1971; the large eruptions are characterized by an explosive onset followed by the quieter effusion of lava. It forms Augustine Island in southwestern Cook Inlet in the Kenai Peninsula Borough of southcentral coastal Alaska, 174 miles southwest of Anchorage. Augustine Island has a land area of 32.4 square miles, while West Island, just off Augustine's western shores, has 2 sq mi. The irregular coastline of Augustine Island is due to the repeated catastrophic collapse of the summit dome, forming debris avalanches down the flanks and into Cook Inlet; the island is made up of past eruption deposits. Scientists have been able to discern; the nearly circular uninhabited island formed by Augustine Volcano is 12 km wide east-west, 10 km north-south.
Augustine's summit consists of several overlapping lava dome complexes formed during many historic and prehistoric eruptions. Most of the fragmental debris exposed along its slopes comprises angular blocks of dome-rock andesite of cobble to boulder size but carrying clasts as large as 4 to 8 meters as large as 30 meters; the surface of such deposits is skeet, a field of steep conical mounds and intervening depressions with many meters of local relief. En route to Katmai in 1913, Robert F. Griggs had inferred landslide as the origin of Augustine's hummocky coastal topography about Burr Point, by geomorphic analogy with the hummocky and blocky deposit of a 1912 landslide near Katmai; the hummocky deposits on Augustine's lower flanks resemble both topographically and lithologically those of the great landslide or debris avalanche that initiated the spectacular May 18, 1980 eruption of Mount St. Helens; the deposit of that landslide revealed the origin of coarse diamicts with hummocky topography at other strato volcanic cones.
Since 1980 many hummocky coarsely fragmental deposits on Augustine's lower flanks have come to be interpreted as deposits of numerous great landslides and debris avalanches. A March 27, 1986 eruption deposited ash over Anchorage and disrupted air traffic in southcentral Alaska. On January 11, 1994, Augustine erupted at 13:44 and 14:13 UTC; the eruption consisted of four "phases", starting in April 2005 and continuing through March 2006. The precursory phase began as a slow, steady increase in microearthquake activity beneath the volcano on April 30, 2005. An earlier swarm in October of 2004 developed seismicity rates that exceeded any observed since the 1986 eruption; the number of located VT earthquakes increased from an average of one to two per day in May 2005 to five to six per day in October 2005 to 15 per day in mid-December 2005. December 2 revealed the onset of a series of small phreatic explosions that were recorded on the Augustine seismic network; the largest of these explosions occurred on December 10, 12, 15.
An observational overflight on December 12 revealed vigorous steaming from the summit area, a new vigorous fumarole on the summit’s southern side at 3,600 ft elevation, a light dusting of ash on the volcano’s southern flanks. A strong plume of steam and gas extended to the southeast; the ash was found to be a mix of weathered and glassy particles. Between December 12, 2005, January 10, 2006, seismicity rates were elevated, with more than 420 earthquakes located by the AVO. Much of this activity occurred in spasmodic bursts similar to those observed before the 1986 eruption; the volcano erupted on January 11, 2006, entering a second "stage", which would continue until January 28. Tectonic earthquakes began early in January, resulting in an explosive Volcanic Explosivity Index 3 eruption in that day. Several ash columns were generated, each 9 km above sea level. Samples of the tephra were dense. Six explosions were recorded by seismic instruments between January 13, the first of these consuming a seismograph and a CPGS located on the northwestern flank.
Ash columns now reached Kenai Peninsula residents reported ash deposits. On January 16, a new lava dome was observed on the summit; this explosion created a 20-30 meter wide crater in the new lava dome. On September 22, 2007, the Alaska Volcano Observatory reported that shallow earthquake activity had increased over the week of September 22. However, the activity was less than its level during the months leading up to the 2005-2006 eruption; the Plate Boundary Observatory, operated by UNAVCO has a network of 10 high-precision GPS instruments on the flanks of Augustine. Activity two years ago claimed two of these sites; the Alaska Volcano Observatory operates a number of seismometers and tiltmeters all around the volcano, including four webcams.

All three sites are managed by the Cook Inlet Aquaculture Association Some of the fish hatched at these facilities are released into the famous Homer fishing hole. Cook Inlet Keeper and the Cook Inlet Regional Citizen's Advisory Council are groups that attempt to influence public policy on the use of the areas resources; as of the census of 2000, there were 49,700 people, 18,400 households, 12,700 families residing in the borough. The population density was 1/km². There were 24,900 housing units at an average density of 2 per square mile; the racial makeup of the borough was 86% white, 7% Native American, 2% Hispanic or Latino, 4% from two or more races. Black or African Americans and Pacific Islanders each were less than 1% of the population. Just under 1% were from other races combined. 1.92 % reported speaking Russian at home. There were 18,400 households out of which 38% had children under the age of 18 living with them, 55% were married couples living together, 9% had a female householder with no husband present, 31% were non-families.
25% of all households were made up of individuals and 5% had someone living alone, 65 years of age or older. The average household size was 2.6 and the average family size was 3.2. In the borough the population was spread out with 30% under the age of 18, 7% from 18 to 24, 30% from 25 to 44, 26% from 45 to 64, 7% who were 65 years of age or older; the median age was 36 years. For every 100 females, there were 109 males. There is a borough-wide government based in Soldotna, consisting of a strong mayor and an assembly of representatives from all areas of the borough, they collect sales and property taxes and provide services such as road maintenance, waste collection facilities, emergency services and major funding for public schools, along with mitigation of damage from spruce bark beetles that infested the borough in the late 1990s and early 2000s. Incorporated towns have their own local governments and city councils; the Alaska Department of Corrections operates the Spring Creek Correctional Center near Seward and the Wildwood Correctional Complex near Kenai.

The Kenai Peninsula is a large peninsula jutting from the coast of Southcentral Alaska. The name Kenai is derived from the word "Kenaitze" or "Kenaitze Indian Tribe", the name of the Native Athabascan Alaskan tribe, the Kahtnuht’ana Dena’ina, that inhabited the area, they called the Kenai Peninsula Yaghanen. The peninsula extends 150 miles southwest from the Chugach Mountains, south of Anchorage, it is separated from the mainland on the west on the east by Prince William Sound. Most of the peninsula is part of the Kenai Peninsula Borough. Gerasim Izmailov was the first European man to explore and map the peninsula in 1789, though Athabaskan and Alutiiq Native groups have lived on the peninsula for thousands of years; the glacier-covered Kenai Mountains, rising 7,000 feet, run along the southeast spine of the peninsula along the coast of the Gulf of Alaska. Much of the range is within Kenai Fjords National Park; the northwest coast along the Cook Inlet is marshy, dotted with numerous small lakes.
Several larger lakes extend through the interior of the peninsula, including Skilak Lake and Tustumena Lake. Rivers include the Kenai River, famous for its salmon population, as well as its tributary, the Russian River, the Kasilof River, the Anchor River. Kachemak Bay, a small inlet off the larger Cook Inlet, extends into the peninsula's southwest end, much of, part of Kachemak Bay State Park; the Kenai Peninsula has many glaciers in southern areas. It is home to both the Sargent Icefield and Harding Icefields and numerous glaciers that spawn off them; the peninsula includes several of the most populous towns in south central Alaska, including Seward on the Gulf of Alaska Coast, Kenai and Cooper Landing along the Cook Inlet and Kenai River, Homer, along Kachemak Bay, along with numerous smaller villages and settlements. Homer famously marks the terminus of the paved highway system of North America and is a popular destination for travelers who have driven to Alaska from the lower 48 states.
Seward is the southern terminus of the Alaska Railroad. There are airports with scheduled flights in Kenai and Homer as well as smaller general aviation airports in Soldotna and Seward; the Seward Highway connects Seward to Anchorage, the Sterling Highway is the backbone of Kenai Peninsula connecting the larger towns to Anchorage. The peninsula has a coastal climate, mild, with abundant rainfall, it is one of the few areas in Alaska that allow for agriculture, with a growing season adequate for producing hay and several other crops. The peninsula has natural gas and coal deposits, as well as abundant commercial and personal-use fisheries. Tourism is guiding services for hunters and fishers; the Kenai Peninsula is known as "Alaska's Playground"
