The Zhouqu landslide in China, in 2010: This landslide was triggered by heavy rainfall and resulted in the deaths of over 1,700 people.
Geological hazards are natural processes or phenomena that can cause damage, destruction, or loss of life to humans and their built environment. These hazards arise from geological processes such as earthquakes, volcanic eruptions, landslides, and floods, which can occur at any time and in any location.Â
Landslides occur when soil and rock suddenly slide down a slope, often due to heavy rainfall or earthquakes. Landslides can destroy homes, and infrastructure, and cause significant loss of life. Landslides can be triggered by a variety of factors, including heavy rainfall, earthquakes, volcanic activity, and human activities such as mining and deforestation. It is important for individuals and communities to be aware of the risks and take necessary precautions to mitigate the impacts of landslides.
Sinkholes are formed when the ground collapses due to the dissolution of soluble rocks such as limestone or dolomite. Sinkholes can be difficult to predict and can occur suddenly, posing a risk to people and infrastructure. To minimize the risk of sinkholes, it is important to properly manage groundwater resources and to avoid building on areas with unstable geological conditions.
The 2006 Guinsaugon landslide in Southern Leyte: This landslide was triggered by heavy rainfall and resulted in the deaths of over 1,000 people.
The 2018 Cebu City sinkhole in Cebu: This sinkhole opened up in the middle of a road and was caused by the collapse of a large underground cavity. No injuries were reported.
