our india suffring from many disaster but mast important disaster is natural disaster . natural disaster is the impact of the human causing the wasteage of natural resoures andusing it very widly range becaus of using natural resoures in bulk amount it harmes pur planet as well as our country .the goverment should take action toward those industries which use the natural resoures in wide range. ande give them punishment to them and save our planet from natural disaters. A natural disaster is the effect of a natural hazard (e.g., flood, tornado, hurricane, volcanic eruption, earthquake, or landslide) that affects the environment, and leads to financial, environmental and/or human losses. The resulting loss depends on the capacity of the population to support or resist the disaster, and their resilience.[1] This understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability."[2] A natural hazard will hence never result in a natural disaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas. The term natural has consequently been disputed because the events simply are not hazards or disasters without human involvement.[3] Natural disasters which occur the movement of plate tectonics are earthquakes, volcanoes, geyser eruptions and tsunami.movement disasters


Avalanche on the backside (East) of Mt. Timpanogos, Utah at Aspen Grove trail Notable avalanches include:
The 1910 Wellington avalanche
The 1954 Blons avalanches
The 1999 Galtür Avalanche
The 2002 Kolka-Karmadon rock ice slide
The 2010 Pacaya Volcano ash disaster
Main article: Earthquake
An Earthquake is a sudden shake of the Earth's crust caused by the tectonic plates colliding.The vibrations may vary in magnitude. The underground point of origin of the earthquake is called the "focus". The point directly above the focus on the surface is called the"epicenter". Earthquakes by themselves rarely kill people or wildlife. It is usually the secondary events that they trigger, such as building collapse, fires, tsunamis (seismic sea waves) and volcanoes, that are actually the human disaster. Many of these could possibly be avoided by better construction, safety systems, early warning and evacuation planning.Earthquakes are caused by the discharge of energy accumulated along geologic fault. [edit]Lahars

A lahar is a volcanic mudflow or landslide. The 1953 Tangiwai disaster was caused by a lahar, as was the 1985 Armero tragedy in which the town of Armero was buried and an estimated 23,000 people were killed. [edit]Volcanic eruptions

Pu'u 'Ō'ō
An Eruption may in itself be a disaster due to the explosion of the volcano or the fall of rock but there are several effects that may happen after an eruption that are also hazardous to human life. Lava may be produced during the eruption of a volcano a material consisting of superheated rock. There are several different forms which may be either crumbly or gluey. Leaving the volcano this destroys any buildings and plants it encounters. Volcanic ash - generally meaning the cooled ash - may form a cloud, and settle thickly in nearby locations. When mixed with water this forms a concrete like material. In sufficient quantity ash may cause roofs to collapse under its weight but even small quantities will cause ill health if inhaled. Since the ash has the consistency of ground glass it causes abrasion damage to moving parts such as engines. Supervolcanoes : According to the Toba catastrophe theory 70 to 75 thousand years ago a super volcanic event at Lake Toba reduced the human population to 10,000 or even 1,000 breeding pairs creating a bottleneck in human evolution. It also killed three quarters of all plant life in the northern hemisphere. The main danger from a supervolcano is the immense cloud of ash which has a disastrous global effect on climate...
