THE PHILIPPINES
INTRODUCTION
-
Made up of 7000 islands
-
Population of 91 million
-
GDP in 2006 was $50,000 per capita (classed as a middle-income by the World Bank)
-
Mostly a mountainous landscape with coastal lowlands.
-
Philippine Plate and the Eurasian Plate
-
Eurasian Plate is forced beneath the Philippine Plate, creating the deep Manila Ocean Trench
-
Destructive plate boundary
-
In the Ring of Fire
Volcanoes:
-
Near a destructive plate boundary, where the Philippine plate is being subducted beneath the Eurasian plate
-
Islands were formed by a combination of folding at the boundary and volcanoes formed from magma that had risen
-
Mount Pinatubo is a volcano that erupted in 1991- Many people were evacuated, buildings collapsed, crops were destroyed and agricultural land was ruined by falling ash
Earthquakes:
-
The Philippine plate and Eurasian plate can become locked together as one moves under the other- This causes the pressure to build up- When the pressure is too much the plates jerk past each other, causing an earthquake
-
Earthquakes also occur at fault lines in the area, where the plate has cracked under pressure
-
An earthquake of magnitude 7.8 occurred on Luzon Island in 1990, killing over 1500 people
Landslides:
-
The Philippines gets a lot of rain- If a lot falls in a short space of time in areas with steep slopes, landslides can occur
-
Landslides can also be triggered by earthquakes
-
A landslide occurred on Leyte Island in 2006 after heavy rainfall for 10 days. A whole village was buried, killing hundreds
Typhoons:
-
The Philippines has around 10 typhoons every year
-
They develop over the Pacific ocean and move westwards over the islands.
-
Typhoon Xangsane swept across Manila and the surrounding denselt populated area in the North in 2006- High winds and torrential rain destroyed homes and caused flooding, landslides and the loss of power and water
Tsunamis:
-
Earthquakes in any of the oceans surrounding the Philippines could cause a Tsunami
-
In 1976 an earthquake of magnitude 7.9 caused a tsunami that hit the coastline around the Moro Gulf on the southern island of Mindanao- Thousands were killed and several cities were devastated
Droughts:
-
Some parts of the Philippines have a distinct wet and dry season, for example Manila is dry between November and April, and wet between May and October
-
Droughts can occur when the wet season hasn't brought enough rain to last the dry season or the dry season is particularly harsh
-
There was a drought on Luzon Island in 2005- The reduction in rainfall decreased water flow in rivers which affected power production in hydroelectric power plants- This affected power supply to the entire region Without power for an extended period, economic and social activity was severely reduced.
Flooding:
-
During the wet season, floods can be caused by typhoons and heavy rain
-
Flooding affects many areas, even some that are also affected by drought
-
Major floods occurred in the lowland areas around Manila in the 1970's and in recent years- Crops were devastated in this major rice growing region
