Mass Wasting Hazards in The Philippines



There are many types of mass wasting hazards that exist. Some are landslides, mud flows, and avalanches. In the islands of the Philippines, there are many volcanoes and mountains. This meaning, there can be a lot of opportunities for avalanches. Avalanches are when a mass of snow, ice, or rocks fall down a mountainside fairly quickly. The Philippines has also been affected by landslides. Landslides include a wide range of movements in the ground such as a deep failure of slopes.


Back in 1999, on August 3, a huge landslide hit Antipolo City tin the Philippines due to a lot of heavy rain approaching the typhoon Olga. This landslide caused a lot of damage and loss of life, it became a death trap when the foundations were filled with water and the whole complex slid down hills. The Philippines began to alert citizens and residents were told to evacuate to the nearest town once the walls of their houses began to crack. They observe and look out for sudden changes in elevation and ground movements to try and prevent citizens from being hurt. Local authorities had warned residents to evacuate hours before the hazard occurred when cracks started to appear on the roads and walls, however, houses higher up on the hill began to slide down and crush those below.

Unfortunately, you cannot prevent such a hazard. Therefore, the Philippines could only prepare for what was coming. The government made sure various tropical cyclone warnings were shown and made sure the public was well aware it was coming. Officials made sure residents living in low areas seeked higher grounds, schools closed, and multiple buildings opened up storm shelters. Emergency shelters were available for those who left their homes.





On February 17, 2006, a huge rock slide and debris avalanche happened in the Philippines leaving over 1,000 people dead. This landslide was followed by 10 days straight of heavy rain and a minor earthquake. Burying a village and an elementary school affecting over 200 students and teachers.
