Only 10% of volcanoes are monitored around the world from which 90% of these are located in MEDC’S ( More Economically Developed Countries) Volcanoes can pose different type of hazards separating into primary and secondary.

Fun Facts Presently‚ 80 per cent of municipal and industrial solid waste in Canada is disposed of by landfilling processes‚ with the remainder disposed through recycling‚ resource recovery and incineration. Recycling one aluminum can saves an amount of energy equivalent to half that can filled with gasoline. Every year nearly 900‚000‚000 trees are cut down to provide raw materials for American paper and pulp mills Benefits:disease control control of vermin that spread disease less chance

Geomorphology - is the science of landforms‚ their origin‚ evolution‚ form‚ and spatial distribution. Denudation - is any process that wears away or rearranges landforms. Processes include weathering‚ mass movement‚ erosion‚ transportation‚ and deposition. Differential Weathering - the effect of different resistance in rock‚ coupled with variations in the intensity of physical and chemical weathering. Dynamic Equilibrium Model - the balancing act between tectonic uplift and reduction rates

Disadvantages: Sea - during a volcanic eruption earthquakes happen‚ and tsunamis may be created. Also‚ if it is a volcanic island‚ the island may be destroyed‚ and there is no escape. Lava flow - these are very slow moving‚ but destructive as they cannot be stopped and they set fire to everything in their path. Pyroclastic flow - these are impossible to outrun‚ travelling at about 300 km/h‚ and are extremely destructive Mudflow/lahar - these are mud rivers that have the consistency of cement
