landslides and avalanches : Avalanches occur in mountainous regions with a thick snow cover while a landslide occurs in sloppy places with loose and muddy soil. Landslides involve the movement of a large mass of earth down a slope and they can be caused by various factors including poor soil structure, rainfall, drought, erosion, and seismic activities (earthquakes). An avalanche is the movement of large snow volumes. An avalanche can be caused by vibrations from an earthquake or in severe conditions loud sounds can disrupt the snow.
earthquake and volcanoes : Volcanoes form at Earth's surface whereas earthquakes originate from deeper within the crust. ... Volcanoes are formed by release of gas and magma. Earthquakes are caused by movement along a fault. Volcanoes lead to the formation of new rock whereas earthquakes simply cause waves which disturb the rock.23-Jul-2018
