1. 7. On February 17, a devastating landslide killed an estimated 1,800 Filipinos in Guinsaugon on the southern part of Leyte Island in eastern Philippines. What might be the cause of this tragic event? explain your answer.
Landslides are mainly caused by gravity acting on weakened rocks and soil that make up a sloping area of land. Both natural and human-related activities like illegal logging can increase the risk for landslides. Water from heavy rainfall is a frequent trigger for landslides.
2. The Guinsaugon landslide in Leyte in February 2006 claimed the lives of many people and buried their town. The authorities blamed it on the loss of trees due to illegal logging. What is the role of the trees that could have prevented the incident?
Explanation:
Trees are important for preventing landslides as they help to absorb rainfall, reduce soil erosion, and provide stability to the ground. During heavy rainfall, trees help to slow down the flow of water, allowing it to seep into the ground rather than quickly running off the surface. Trees also help to anchor the soil, making it less likely to be washed away. In the case of the Guinsaugon landslide, the trees may have been able to slow down the flow of water and reduce the amount of soil erosion, both of which may have helped to prevent the incident.

What is the role of the trees that could have prevented the incident? Enumerate how trees could prevent soil erosion:
the tree's roots could hold the soil firmly in its place, therefore preventing soil erosion, landslides massive flooding etc.
I couldn't number the trees but if I need to, I would estimate about.. 20 large trees stationed at the right place could totally save a lot of people

5. force of landslide?
Answer:
Gravity is the driving force behind landslide flow. Gravity is the attractive force between all massive objects. ... Gravity produces the weight of an object, which can cause an object to move down an inclined surface. The resisting forces are forces that cause the landslide material to resist the downward pull of gravity.

10. Types of landslide and factors that influence landslide development
Answer:
There are several different types of landslides, and they can be broadly classified based on the type of material involved and the manner in which the landslide occurs. Some common types of landslides include:
•Debris slides: These are landslides that involve a mix of rock and soil, and they can be further divided into debris flows (which involve a high degree of fluidity) and debris avalanches (which are more chaotic and involve a large amount of material).
•Rock slides: These landslides involve the sudden and rapid movement of large blocks of rock down a slope.
•Earth slides: These landslides involve the slow and gradual movement of soil and rock down a slope.
The factors that influence landslide development include:
•The type and structure of the underlying rock or soil: Different types of rock and soil have different properties and are more or less prone to landslides. For example, clay soils are more susceptible to landslides than sand or gravel soils because they are more easily weakened by water.
•The slope of the land: The steeper the slope, the greater the potential for landslides.
•The amount and distribution of moisture in the ground: Wetter conditions make the ground more unstable and can lead to landslides.
•The presence of vegetation: Vegetation can help to hold the ground in place and prevent landslides.
•Human activities: Human activities such as construction, logging, and mining can weaken the ground and make it more susceptible to landslides.

16. What are the two types of landslides?What are the conditions that trigger landslides?
Answer:
The two major types of landslides are rotational slides and translational slides.
Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.
Answer:
Rotational slides and Translational slides
Explanation:
Any geological mechanism in which gravity induces rock, dirt, artificial fill or a mixture of the three to move down a slope is a landslide. Several factors, including the slow weathering of rocks and soil erosion, earthquakes and volcanic activity, can cause landslides.

27. a volcanic landslide?
Answer:
Landslides are common on volcanic cones because they are tall, steep, and weakened by the rise and eruption of molten rock. Magma releases volcanic gases that partially dissolve in groundwater, resulting in a hot acidic hydrothermal system that weakens rock by altering minerals to clay.
Answer:
Landslides are common on volcanic cones because they are tall, steep, and weakened by the rise and eruption of molten rock. Magma releases volcanic gases that partially dissolve in groundwater, resulting in a hot acidic hydrothermal system that weakens rock by altering minerals to clay. Furthermore, the mass of thousands of layers lava and loose fragmented rock debris can lead to fault zones that move frequently.
Volcano landslides (debris avalanches) range in size from less than 1 km3 (0.24 mi 3) to more than 100 km3 (24 mi3. The high velocity and great momentum of landslides allows them to cross valley divides and run up slopes several hundred meters high. For example, the landslide at Mount St. Helens on May 18, 1980, had a volume of 2.5 km3(0.6 mi3), reached speeds of 50-80 m/s (100-180 mi/hr), and surged up and over a 400-m-tall (1300 ft) ridge located about 5 km (3 mi) from the volcano.Early on the morning of May 18, 1980, the landslide swept into the upper North Fork Toutle River valley and came to rest within about 22 km of the volcano. The landslide deposit, however, was saturated with water, and contained snow and ice blocks from the volcano's former glaciers. As soon as the landslide stopped moving, water percolated to the top of the deposit and poured across its irregular surface, forming many lahars that merged as they rushed down the valley. The peak flow swept from the deposit about 5 hours after the landslide was emplaced!
The lahar flowed down the Toutle River throughout the afternoon and evening, reaching its peak at midnight about 60 km downstream from the volcano. The lahar destroyed roads, bridges, and homes
