Benefits of Volcanic Eruptions Volcanic eruptions present various dangers to humans and to wildlife habitats. But volcanoes also provide benefits to humans and to the environment. These benefits include fertile soils, a renewable energy source, and construction materials.ey Concept The effects of volcanic eruptions can change human and wildlife habitats. â¢ Volcanic eruptions can cause the loss of human life and the devastation of wildlife habitats. â¢ Volcanic eruptions can cause the average global temperature of Earth to decrease.
It's not possible to prevent earthquakes and volcanic eruptions. However, careful management of these hazards can minimise the damage that they cause. Prediction is the most important aspect of this, as this gives people time to evacuate the area and make preparations for the event.he higher the sulfur content of these gases, the closer the volcano is to erupting. Gas samples may be taken and chemical sensors used to measure sulfur levels. The techniques available for predicting and monitoring volcanic activity are becoming increasingly accurate.
