Question

Make a collection of news,photos and cutting about land slides

and rift collapse and explain.​

Answer 1

A variety of ground movements, including rockfalls, deeply seated slope failures, mudflows, and debris flows, can occur during landslides, also known as landslips.

• A rift zone is a characteristic of some volcanoes, particularly shield volcanoes, where a series of linear fissures (or rifts) occur in a volcanic edifice, usually forming into two or three distinct zones along the flanks of the vent.

• In a number of locations, including mountain ranges, coastal cliffs, and even underwater, where they are known as submarine landslides, landslides can occur and are characterised by either steep or gradual slope gradients.

• Rift zones enable the intrusion of magmatic dykes into the volcano's slopes and are thought to be primarily caused by internal and gravitational stresses generated by magma emplacement within and across various parts of the volcano.
• In addition to causing fissure eruptions from those dykes that reach the surface, the addition of these magmatic materials typically adds to the slope's continued rifting.
