Exam Question - Choose either the Philippines or California and explain why it is considered a disaster hotspot. (10 marks) The Philippines is considered a disaster hotspot, susceptible to volcanoes, earthquakes, typhoons, tsunamis and floods. The Philippines in very vulnerable to hazards as poverty and human development is so variable; in outlying areas and small islands. Increasing urbanisation can add to earthquake and typhoon vulnerability. Physical factors have also affected the vulnerability of The Philippines, such as slopes, increase land degradation and deforestation have increased susceptibility to secondary hazards such as landslides during earthquakes and flash flooding during typhoons. A disaster hotspot is a location with risk from two or more hazard groups: tectonic hazards (geophysical)
The plates move in a series of 'jerks' producing an earthquake each time they do so, this kind of plate boundary is called a destructive plate boundary. The harshest volcanic eruptions occur along destructive plate boundaries. As the subducted Eurasian plate melts the earth's mantle, the molten rock forms a magma chamber, some of this magma then becomes explosive when combined with gases within the chamber. The magma then solidifying just below the earth's surface producing a solid cap over the volcanoes outlet or vent. Pressure grows beneath, so when a volcanic blast does happen, it does so with incredible force.
80 000 hectares of farmland were buried beneath ash, disrupting the livelihoods of 500 00 farmers and their families. Economic losses were US$710 million, mainly on agriculture and building. Some hazard risks in The Philippines are complex because they have multiple effects; In October 2009 the country was hit by three Typhoons all in the space of one month. More than 100 000 people were moved out of their homes, many of those had just moved back after escaping earlier typhoons, which dropped a month's rain on the island in one day. Around 1100 killed in landslides, floods and related bacterial infections after the earlier typhoons. Another example is one Earthquake in 2006 which generated 3 tsunamis, also triggered landslides and created floods which washed away houses. ?? ?? ?? ?? Amrit Singh Thabal 16MB Geography
