'Why California is considered a hazard hotspot and how it copes\r'

'A disaster hot spot is somewhere where there is a threat of twain or more hazards to the bea, ranging from geophysical to hydro-meteorological hazards. This is certainly the drive in calcium, where there are an abundance of hazards which threaten the safety of the population. These hazards include seisms, bushfires, landslides, flooding, drought and fog. A study threat to the 40million strong population of California is earthquakes, which are caused by a network of active faults which comport under the coastline of the state, including the San Andreas Fault and the Garlock Fault.\r\nThe San Andreas Fault is a buttoned-down boundary, which groundwork give rise to powerful earthquakes. The 1906 San Francisco earthquake was caused by a rupture on the San Andreas Fault, which is a strike-slip fault meaning it is a crack amidst two plates sliding past each other. This 7. 7 magnitude earthquake caused a hatful of closing in the San Francisco battleground, killing an estimate d 3000 passel and leaving an big-ticket(prenominal) bill of damage ($9. 5 billion in 2009 dollars). Much of the damage and death toll came as a result of the devastating fires which followed the earthquake, which lasted for four days.\r\nThe lot of California are vulnerable to earthquakes as the faults presently underlie the area and the earthquake events cannot be predicted. As California is part of one of the largest economies in the world, it can afford preventive measures such as an annual earthquake drill and building earthquake test copy buildings. Drought is another prevalent threat in California, which also gives rise to wildfires due to dry grand and air. Droughts are caused by a lack of precipitatefall, heightened by the onset of La Nina.\r\nA especially unfit example of a drought in California was in 1976-77 where they only had half the rainfall compared to a normal year, causing a major pare fail, which in less economically developed countries very much leads to a famine disaster. Droughts lead to health problems, particularly for the young and old who are at assay of malnutrition and heatstroke. 2007 was a bad year for wildfires. Prior to these fires the area was experiencing a drought, meaning the land was dry which created dandy conditions for fires to spread.\r\nAcross the 19 days of suntaning, there were 9 deaths, over 500,000 acres of land burned, along with 1500 homes. in that respect had been a build up in bushes in the previous decades of no fires which added to the reason the fires were so noxious as they had a lot of fuel to burn on. California is also at risk of flooding, both coastal and from rivers. These events are largely caused by ebullient rainfall. In 1964 the Alaskan earthquake caused a tsunami which devastated move of California, killing 14 residents.\r\nA more new-fashioned example of flooding was in December 2010 when hundreds of people were evacuated due to more than 12 inches of torrential rain falling, causing flooding and mudslides. This again caused a lot of economic damage. Other mudslides have occurred across the youthful decades, often caused by earthquakes or flooding and erosion. In La Conchita there have been two major mudslides, one in 1995 the other in 2005. The more recent event was far more destructive, burying 15 homes and killing 10 people and was caused by excessive rainfall.\r\nIn conclusion California is considered a disaster hotspot because its population is vulnerable to a variety of hazards which occur quite frequently and some terms lead on from one another, for example if there is an earthquake landslides could occur as well as the initial destruction caused by the earthquake itself. As a developed state it has invested money and time to ensure the safety of its residents as much as is possible when the events are unpredictable.\r\n'
