The intermittent eruptions continued upto December 21,when the volcano became dormant. Thus, on the basis of the nature and intensity of eruptions volcanoes are divided into two types e. A third category of environmental hazard has been increasingly employed to describe events with the potential for catastrophic impact on the global environment.
A few of the severe damages wrought by volcanic eruptions may be summarized as given below: The lavas are so viscous and pasty that these are quickly solidified and hardened between two eruptions and thus they crust over plug the volcanic vents. In fact, volcanic eruptions are very closely associated with the plate boundaries.
Natural hazards are elements of circumstances in the natural environment that have the potential to cause harm to people or property or both.
The enlarged form of the volcanic vent is known as volcanic crater and caldera. Lava flow is divided into two types on the basis of Hawaiin language e. Social scientists using a human ecology framework began to investigate disaster prevention and the mitigation of its consequences. These are also known as tephra which means ash.
These are more or less similar to Vulcanian and Strombolian type of volcanoes, the difference lies only in the intensity of expulsion of lavas and gases. This example Environmental Hazards Essay is published for educational and informational purposes only.

Volcanoes are also associated with the meeting zones of the continents and oceans. The disastrous cyclones occur every five years.
Destructive or convergent plate boundaries are associated with explosive type of volcanic eruptions. Such volcanoes erupt quietly due to less viscous lavas and non-violent nature of gases.
In other words, two plates diverge in opposite directions from the mid-oceanic ridge. The first Yellowstone supervolcanic eruption 2. Environmental Hazards Essay An environmental hazard is a threat posed by the natural or built environment to humans and the things that are valued in human society.

geologic (especially seismic and volcanic), and wildfire phenomena that. The heavy rainfall, associated with volcanic eruptions, mixing with falling volcanic dusts and ashes causes enormous mudflow or ‘lahar’ on the steep slopes of volcanic cones which causes sudden deaths of human beings.
Natural Hazards Center - The Natural Hazards Center (NHC), in the Institute of Behavioral Science, at the University of Colorado, Boulder, was established in to enhance and contribute to the knowledge base of the then young, academic field of disaster research and.
