Relatively less dangerous mass downslope movement which involves the slow downslope movement of soil and weak rocks on the surface. This movement can tilt fences, power lines and tress. It is an indication that the slope is unstable.

• Creep

• Landslide

• Rock fall

• Flow

Rapid movement of rocks and soil. They are very dangerous because they flow at a speed of 100 to 300 km/hr and may contain boulders or large rocks.

• Landslide

• Debris Avalanche

• Flows

• Rock Flow

Loose natural material consisting especially of broken pieces of rock

• Avalanche

• Debris

• Rock

• Fragment

Is a geological process by which soil, sand and rock move downslope typically as a solid continuous or discontinuous mass, largely under the force of gravity.

• Limestone

• Flow

• Mass Movement

• Landslide

a sedimentary rock composed primarily of calcium carbonate (CaCO3)

• Limestone

• Sandstone

• Shale

• Clay

An aggregate of one or more mineral

• Fragment

• Debris

• Avalanche

• Rock

Science that studies the nature and history of landforms and the processes of weathering, erosion and deposition that created them.

Happens when the soil cover is thin and highly permeable so that acidic groundwater can seep easily through it and dissolve the underlying limestone bedrock.

• Cover Subsidence

• Dissolution

• Cover Collapse

Occurs suddenly and without warning. This is the deadliest among the three

• Dissolution

• Cover Subsidence

• Cover Collapse

This may result to numerous sinkholes
