CHAPTER 1
The Problem and Its Background
Introduction
Philippines is situated in the world’s hazard belts and are subject to floods, droughts, cyclones, earthquakes, windstorms, tidal waves and landslides, etc. The major natural disasters that occur periodically are largely due to climatic and seismic factors.
Disasters can result from meteorological phenomena such as typhoons and hurricanes, sheet flooding and marine and river-based floods, geological processes such as volcanic eruptions, earthquakes and tsunami and climatic phenomenon such as the El Nino Southern Oscillation that results in a lowering of mean sea level in the east of the region, failure of the monsoon rains in India, and drought in Indonesia and Australia.
The Philippines has a tropical marine climate dominated by a rainy season and a dry season. The summer monsoon brings heavy rains to most of the archipelago from May to October, whereas the winter monsoon brings cooler and drier air from December to February. Most of the lowland areas are hot and dusty from March to May. Annual rainfall measures as much as 5,000 millimeters in the mountainous east coast section of the country, but less than 1,000 millimeters in some of the sheltered valleys. Monsoon rains, although hard and drenching, are not normally associated with high winds and waves. But the Philippines do sit astride the typhoon belt, and it suffers an annual onslaught of dangerous storms from July through October.
In the last decade, the Philippines have suffered severely from natural disasters. In 1990 alone, Central Luzon was hit by both a drought, which sharply

    The Philippines are largely affected by geophysical hazards, mainly by tectonic hazards such as earthquakes and volcanoes, these hazards occur due to the Philippines geographical location, it is located between 2 destructive plate boundaries of the Eurasian plate and the Philippines plate which when submerging under one another create allot of friction which causes heat, this melts the submerging plate under the Philippine islands themselves which form volcanoes on the islands such as Mayon which prove to be quiet catastrophic when erupting. The friction created by the submergence of the plate can also be felt as an earthquake and as the plate boundaries are quiet close to the islands the earthquakes are generally more powerful like the Manila earthquake January 11, 1982 which was registered 6.9 on the Richter scale. As the Philippines are also surrounded by sea and oceans tsunamis is a large possibility, when an earthquake under sea occurs the water above it gets shaken causing waves which get larger as they close in to the shores. This is a large threat to the Philippines as it is formed of 7 thousand islands most of them relatively close to the sea level meaning that they can get submerged by waves not that high, a 7.9 magnitude earthquake hit the east cost of the Philippines on August 16th, 1976 12:11 A.M., this created a tsunami devastating 700km of coastline bordering Moro Gulf in the North Celebes Sea this tragedy left 5,000 dead, 2,200 missing, 9,500 injuries and a total of 93,500 people left homeless.…

    California is an MEDC, the 6th largest economy in the world with a GDP of US$65000 per capita. However, despite the high risk of hazards it is a very desirable place to live because of its relaxed lifestyle and natural beauty. The population is growing mainly due to immigration which means that cities such Los Angeles are becoming more vulnerable. The Philippines is a Newly Industrialised Country (NIC) and has low to middle income of US$5000 per capita. Their economy is mostly dependant on agriculture (because of the rich, fertile soils on the volcanic hills), manufacturing and tourism, which are all at risk from the natural disasters. Although it is only a small group of islands, the population is huge at 91 million (over twice the size of California's). Both California and the Philippines lie on plate boundaries and therefore both suffer from tectonic hazards. As with all plate boundaries, friction often builds up between the plates also causing regular earthquakes which can sometimes result in tsunamis as well. In the Philippines earthquakes have multiple impacts. This is partly to do with the physical geography of the land. Being a group of islands means that the epicentres of the earthquakes are often in the sea, which increases the likelihood of tsunamis. It is also very mountainous inland which means many areas are vulnerable to landslides. One earthquake in 2006 triggered landslides, a flood and a local tsunami 3 feet high. Another relatively minor earthquake was one of the causes of a catastrophic mudslide, killing1150 people. The Philippines does not have the economic resources to deal with the…

    Many people face dire situations everyday, but what about deadly? This is what about 43,000 Filipinos faced on October 15, 2013 when a deadly 7.2 magnitude earthquake struck the islands of Bohol and Cebu. The temblor was the largest to shake the area in 23 years. (BK Info) Also, 2211 aftershocks hit the region and most citizens were completely unprepared, and shocked. The cause of this disaster is likely the East Bohol Fault. The quake killed around 185 people and put at least 36,000 buildings (mainly homes) into a state of destruction. Various locations were now just heaps of wreckage, including ports, schools, airports, hospitals, and lots of houses. People respond to a natural catastrophe by gathering supplies, getting help, and trying to survive and get back upon their feet.…

    How would you feel if someone told you that in the next 5 seconds that your life would be turned upside down? The same exact thing happened to people in central Philippines, the only thing different is that they got no warning. A deadly earthquake with a magnitude of 7.1 struck central Philippines on a national Islamic holiday. The temblor was the strongest to shake the area in 23 years. Powerful aftershocks continue to hit widely across Bohol and Cebu. More than 2.6 million people live in Cebu, and about 12 million people live in Bohol (Background Essay). People respond to a natural disaster by getting involved with organizations that help the victims of the natural disaster, gathering supplies, and by evacuation centers opening up…

    All communities - urban or rural - are vulnerable to most hazards. However, different regions will be more prone to certain types of hazards than others. Floods and windstorms are the hazards that most frequently lead to disasters in Asia, the Pacific, Europe and North America, while it is droughts and epidemics that are reported in African countries. In contrast, Pacific and Caribbean islands are most vulnerable to the effects of tropical cyclones. El Niño events, floods, volcanic eruptions and earthquakes affect in greater degree the Andean and Meso-American countries. Even within a specific region, such as the Pacific, the frequency and intensity of specific hazards varies from one country to another. Hydrometeorological hazards are most common and floods alone account for two-thirds of people affected by natural hazards…

    Nations abroad, individuals, families and entire communities are experiencing unprecedented disasters. Disasters occur suddenly and unexpectedly, and they often cannot be prevented. A disaster is any natural or human made incident that causes disruption, destruction or devastation requiring external assistance (Stanhope & Lancaster 2014). It seems as though more and more disasters are occurring more frequent than in years past. There are two types of disasters, natural disasters as well as human-made disasters. Natural disasters are defined as unpreventable…

    I learned how to read at a very early age of five. Not only did I know how to read in English but I also learned how to read in Spanish. For kindergarten I went to an imersion program which taught me both English and Spanis. My parents were very suprised I was able to read in both languages since I wasnt fluent at the time. I had no idea it was such ancawesome accomplishment until later on. I am really thankful for the teacher I had Señora Carmona. She was the one who really developed my reading skills and I am very thankful for tha. At five years old you dont know how smart you are until you look back amd you're like Wowwww! I was able to do that. For some people it is still hard to read in their first language let alone in another. One day Señora Carmona called my parents in for a parent teacher conference. At the time my parents were a little worried that I had gotten in trouble. When my parents went into class my Dad and Señora Carmona realized they went to high school together so it broke the ice a little. They spent a little time catching up and then she began to talk about me.she told them how amazed she was on how I was doing compared to the rest of the kids in the class. My parents were so proud of me. They couldnt believe I was reading better than both the American kids in English and the hispanic kids in Spanish. As parents they felt a sense of accomplishment. I look back and I really appreciate what I had learned back then because it has helped me out in so many ways. I will never forget Señora Carmona and if I saw her today I would thank her for all she had taught me.…

    case study of mount pinatubo

    • 7231 Words
    • 29 Pages

    Mount Pinatubo volcano erupted in June 1991 in the main island of Luzon belonging to the Philippines archipelago. Huge economic losses and population exodus have followed. This major crisis has been relayed with other crisis due to lahars which have been supplied with eruption deposits. These lahars have occurred every year since 1991 during the rainy season. They will probably last until 2005. After a brief presentation of the Philippine official response system to disasters, this paper draws up a critical analysis of the different kinds of institutional and social responses deployed to manage the different crisis and post-crisis phases of this event. Based on three viewpoints: from population, media and other actors, this analysis attempts to point out the strengths and weaknesses of the official management system, especially by studying the efficiency and the range of the taken solutions. So, it appears that the management of the June 1991 main crisis (eruption) was a success. On the other hand, difficulties have occurred with lahars risk management. Indeed, these lahars have obliged the authorities to protect and reaccommodate thousands of people. In spite of persistent problems, the management system (monitoring/warning/evacuation) of lahar crises improves year after year. Failures appear especially about rehabilitation program (protection/rehousing). Many of direct (lack of means, of preparedness, of coordination, of dialog, etc.) and indirect (politico-administrative, socio-economic, cultural contexts) factors come to lock the wheels of the institutional response system. They defer the socio-economic start of this north Philippines vital area.…

    Natural Disaster

    • 2262 Words
    • 10 Pages

    A natural disaster is the effect of a natural hazard (e.g., flood, tornado, hurricane, volcanic eruption, earthquake, heatwave, or landslide). It leads to financial, environmental or human losses. The resulting loss depends on the vulnerability of the affected population to resist the hazard, also called their resilience. This understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability." A natural hazard will hence never result in a natural disaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas. The term natural has consequently been disputed because the events simply are not hazards or disasters without human involvement. A concrete example of the division between a natural hazard and a natural disaster is that the 1906 San Francisco earthquake was a disaster, whereas earthquakes are a hazard. This article gives an introduction to notable natural disasters, refer to the list of natural disasters for a comprehensive listing.…
