‘The extent to which volcanic processes represent hazards depends on where and when they occur’. Discuss this statement A hazard can be defined as a situation that poses a threat to life‚ health‚ property or the environment. The severity and type of volcanic hazards that occur are mainly dependent on the type of magma. Volcanic processes can be split into two categories – primary hazards and secondary hazards. The primary hazards that can occur are pyroclastic flows‚ lava flows‚ tephra and poisonous

environment. Therefore‚ in this case a volcanic hazard is the threat posed from natural volcanic processes towards the populations and the environment. The extent of volcanic hazards can vary due to two factors; physical factors such as the type of volcano and human factors such as the population density in the area. Volcanic hazards can also be placed into two phases: primary hazards such as lava flows and gas emissions; there are also secondary hazards such as lahars and landslides. The management

Review questions 1-10 Pages 146-147 1. Describe the three different kinds of material that can erupt from a volcano. Products of eruption come in three forms; lave flow‚ which can be Basaltic‚ Andesitic or Rhyolitic lava. A volcano also erupts pyroclastic debris (when lava flies into the air and freezes) and gases. 2. Contrast a pyroclastic flow with a lahar. Pyroglastic debris are blasting clots of lava‚ and the lahar are like mudslides that can reach up to 50km per hour. When the

MOUNT VESUVIUS FACTS Mount Vesuvius is probably the most famous volcano EVER! I wrote a couple of interesting facts that you can copy and paste freely for your term paper or geography project. * Situated in Naples‚ Italy‚ Mount Vesuvius which is 19‚ 000 years old is a stratovolcano. This volcano can be recognized even from a distance‚ due to its characteristic feature of a ’humpback’ mountain. Volcanoes are classified according to their shapes and Mount Vesuvius is a stratovolcano.

VOLCANO DESTROYS ITSELF IN VIOLENT ERUPTION. After lying dormant for 123 years the build-up of pressure causes Mt St Helens to erupt violently. At least 57 people have died after the massive eruption of Mount St Helens volcano in Washington State‚ USA. Many more are missing and the death toll is expected to rise. A huge cloud of ash has turned day into night for towns and cities across north-western America. People have been told to stay indoors and wear gauze masks. Many roads have been closed
