Why are some volcanoes more hazardous than others? There are several reasons that influence volcanic hazards‚ these include the viscosity of the magma‚ proximity to population centres‚ materials that are ejected from the volcano‚ the magnitude of the eruption and the plate margin that the volcano rests upon. The viscosity of the magma depends on 3 things‚ the temperature‚ dissolved gasses and the chemistry involved in the magma. These factors produce 2 main types of magma called acid and basic

This reduces the scientists’ credibility in the eyes of government and local people‚ and can cause problems the next time an eruption seems likely. 7. Prediction‚ forecasts and reactions - Active volcanoes all over the world are monitored using a vast array of scientific equipment. Satellites look for infrared radiation that indicates rising magma and ground instruments measure gas emissions‚ ground deformation and resulting earthquake activity. - Geologists use evidence from past eruptions

the crater never gets plugged. This is the calculated risk that people take in order to live productive farming lives on the sides of volcanoes. The other main factor that is the cause for people living so close to volcanoes is geothermal energy. Heat from the earth’s crust is being converted into heat energy. In very cold countries with a high number of volcanoes this can therefore be very useful. For example in Iceland this method is used. The volcano Eldfield‚ Haemaey here has created many positive

Volcanoes are big erupting mounting that shoot out hot lava/magma. Volcano eruptions produce a lot of toxic gases which can damage the environment. When a volcano is about to erupt there is rain‚ thunder‚ and lightning. Volcanoes can also be bigger or smaller than a mountain. There are many different types of volcanoes that cause destruction throughout the entire world. Volcanoes occur all over the world anytime of the day. Volcanoes occur at the mid-ocean ridges because they are divergent plate

Some competitive advantages are fleeting. The successful companies are those that leverage their competitive advantage successfully and repeatedly. As understood by us in the above example the competitive advantage that the cyrptoses enjoy is a direct outcome of its natural habitat and hence the circumstantial gain over its rivals
