Free Essays on San Francisco Earthquake

On April 18, 1906, shortly after 5:00 a.m., a great earthquake struck San Francisco and a long narrow band of towns, villages, and countryside to the north-northwest and south-southeast. Many buildings were wrecked; hundreds of people were killed; electric power lines and gas mains were broken. Fires broke out and burned wildly for days, utterly out of control because of severed water mains. The ground had broken open for more than 270 miles along a great fault - the San Andreas rift. The country on the east side of the rift had moved southward relative to the country on the west side of the rift. The greatest displacement had been 21 feet about 30 miles northwest of San Francisco. Nearly all the scientists in California began immediately to assemble observations on the results of the quake. Professor A.C. Lawson, chairman of the geology department at the University of California, took the first steps that led to Governor George C. Pardee's appointment, three days after the shock, of a State Earthquake Investigation Commission to unify the work of scientific investigations then under way. The members of this Commission were Professor Lawson, Chairman; J.C. Branner, professor of geology at Stanford University; Charles Burckhalter, director of the Chabot Observatory at Oakland; W. W. Campbell, director of Lick Observatory; George Davidson, professor of astronomy at the University of California; G.K. Gilbert, geologist of the U.S. Geological Survey; A. O. Leuschner, professor of astronomy at the University of California; and H.F. Reid, professor of geology at Johns Hopkins University. With the exceptions of Gilbert and Reid, none of the Commission members were the n known as students of earthquakes. Nevertheless, they were a distinguished and highly competent group of men. Two of the geologists and two of the astronomers were then members of the National Academy of Sciences and three others subsequently became members of that body. ...

The History and Geography of Iceland

The History and Geography of Iceland Population: 306,694 (July 2009 estimate)Capital: ReykjavikArea: 39,768 square miles (103,000 sq km)Coastline: 3,088 miles (4,970 km)Highest Point: Hvannadalshnukur at 6,922 feet (2,110 m)Iceland officially called the Republic of Iceland, is an island nation located in the North Atlantic Ocean, just south of the Arctic Circle. A large part of Iceland is covered with glaciers and snowfields and most of the countrys inhabitants live in the coastal areas because they are the most fertile regions on the island. They also have a milder climate than other areas. Iceland is highly active volcanically and has recently been in the news due to a volcanic eruption under a glacier in April 2010. The ash from the eruption caused disruptions all over the world. History of Iceland Iceland was first inhabited in the late 9th and 10th centuries. The main peoples to move to the island were the Norse and in 930 C.E., the governing body on Iceland created a constitution and an assembly. The assembly was called the Althingi.Following the creation of its constitution, Iceland was independent until 1262. In that year it signed a treaty which created a union between it and Norway. When Norway and Denmark created a union in the 14th century, Iceland became a part of Denmark.In 1874, Denmark gave Iceland some limited independent ruling powers, and in 1904 after a constitutional revision in 1903, this independence was expanded. In 1918, the Act of Union was signed with Denmark which officially made Iceland an autonomous nation that was united with Denmark under the same king.Germany then occupied Denmark during World War II and in 1940, communications between Iceland and Denmark ended and Iceland attempted to independently control all of its land. In May of 1940 though, B ritish forces entered Iceland and in 1941, the United States entered the island and took over defensive powers. Shortly thereafter a vote took place and Iceland became an independent republic on June 17, 1944.In 1946, Iceland and the U.S. decided to end U.S. responsibility for maintaining Icelands defense but the U.S. kept some military bases on the island. In 1949, Iceland joined the North Atlantic Treaty Organization (NATO) and with the start of the Korean War in 1950, the U.S. again became responsible for defending Iceland militarily. Today, the U.S. is still Icelands main defensive partner but there are no military personnel stationed on the island and according to the U.S. Department of State, Iceland is the only member of NATO with no standing military. Government of Iceland Today Iceland is a constitutional republic with a unicameral parliament called the Althingi. Iceland also has an executive branch with a chief of state and head of government. The judicial branch consists of the Supreme Court called Haestirettur, which has justices who are appointed for life, and eight district courts for each of the countrys eight administrative divisions. Economics and Land Use in Iceland Iceland features a strong social-market economy typical of Scandinavian countries. This means its economy is both capitalistic with free-market principles but it also has a large welfare system for its citizens. Icelands main industries are fish processing, aluminum smelting, ferrosilicon production, geothermal power, and hydropower. Tourism is also a growing industry in the country and the associated service-sector jobs are growing. In addition, despite its high latitude, Iceland has a relatively mild climate due to the Gulf Stream which allows its people to practice agriculture in the fertile coastal regions. The largest agricultural industries in Iceland are potatoes and green vegetables. Mutton, chicken, pork, beef, dairy products, and fishing also contribute considerably to the economy.   Geography and Climate of Iceland Iceland has a varied topography but it is one of the most volcanic regions in the world. Because of this, Iceland has a rugged landscape dotted with hot springs, sulfur beds, geysers, lava fields, canyons, and waterfalls. There are approximately 200 volcanoes in Iceland and most of them are active. Iceland is a volcanic island primarily because of its location on the Mid-Atlantic Ridge which separates the North American and Eurasian Earth plates. This causes the island to be active geologically as the plates are constantly moving away from each other. In addition, Iceland lies on a hotspot (like Hawaii) called the Iceland Plume which formed the island millions of years ago. As a result in addition to earthquakes, Iceland is prone to volcanic eruptions and features the aforementioned geologic features such as hot springs and geysers. The interior portion of Iceland is mostly an elevated plateau with small areas of forest but little land suitable for agriculture. In the north, however, there are extensive grasslands which are used by grazing animals such as sheep and cattle. Most of Icelands agriculture is practiced along the coast.Icelands climate is temperate because of the Gulf Stream. Winters are usually mild and windy and summers are wet and cool.
