The Effects of 1991 Mt. Pinatubo Eruption
PINATUBO: POSITIVE EFFECTS
Tourism: Many active and dormant volcanoes bring hundreds of thousands of tourists to those areas each year. In regard to transportation, restaurants, shops, and hotels, this tourism generated a lot of employment. Volcanoes can create new land for human habitation. In Building Materials like Granite, which is used in the construction industry, is formed by volcanic activity. And in the Fertile Soils, the Volcanic soils are very fertile. These rich soils are called laterite soils and are rich in minerals. Scientists from the US Geological Survey and the Philippine Institute of Volcanology and Seismology now closely monitor Mount Pinatubo.
PINATUBO: NEGATIVE EFFECTS
The effects of lahars and floods on people is not complete without mentioning damage to infrastructure and agricultural lands--damage that has profoundly affected livelihood and quality of life. Lahars inundated 15 km of roads, damaged 13 major bridges throughout the 1991-92 period, and threaten to affect another 10 bridges in the coming years. Most of these families once lived in the densely populated barangays of Pampanga, the province that bore the brunt of lahars in the first 2 years. Porac, one of the most severely affected of central Luzon's once bustling towns, symbolizes Pampanga's travails. Many of its residents have left. The former residents of barangays devastated by lahars, the disaster mitigated an internal process of social differentiation. Prior to the calamity, the population in these villages was divided into those with access to agricultural assets or opportunities for overseas employment and those without. Lahars buried agricultural lands, equipment, and houses in these communities regardless of the wealth of the owner.
