Document Summary
Natural hazards: a natural hazard is any geologic/geomorphological process/event which has an adverse socio-economic or life-threatening impacts on humans. Where humans live/work/change the landscape and the natural processes can become hazardous. Generally, there tends to be greater loss of life in undeveloped countries where as developed countries have better resource but the financial impact is greater. Flooding naturally replenishes nutrients and that is a benefit of rivers throughout the land. Hurricanes can bring new life to long-polluted ecosystems. When ocean water is brought to a land basin. Volcanoes can create more land on it as the magma meets the water. Volcanic activity can release huge amounts of ash and deposit a lot of ash around the venting area and the ash is mineral rich and is nutritious and the agriculture community is benefited. Rivers flood quite frequently in canada especially with winter melting. Volcanoes can erupt along the pacific caldera in bc and yukon.
