Geophysics

Natural hazard events can be classified into two broad categories: geophysical and biological.
Geophysics is applied to societal needs, such as mineral resources, mitigation of natural hazards and environmental protection.

Avalanche

avalanchesavalanchingavalanche research
Geophysical hazards encompass geological and meteorological phenomena such as earthquakes, volcanic eruptions, wildfires, cyclonic storms, floods, droughts, avalanches and landslides.
In mountainous terrain, avalanches are among the most serious objective natural hazards to life and property, with their destructive capability resulting from their potential to carry enormous masses of snow at high speeds.

Natural disaster

natural disastersnaturaldisaster
An example of the distinction between a natural hazard and a natural disaster is that the 1906 San Francisco earthquake was a disaster, whereas living on a fault line is a hazard.
A natural disaster is a major adverse event resulting from natural processes of the Earth; examples are floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, and other geologic processes.

Human impact on the environment

anthropogenichuman activityhuman impacts
Some natural hazards can be provoked or affected by anthropogenic processes (e.g. land-use change, drainage and construction).
Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires.

Act of God
In legal usage throughout the English-speaking world, an act of God is a natural hazard outside human control, such as an earthquake or tsunami, for which no person can be held responsible.

Natural Hazards of the U.S. Geological Survey
The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology.

Social vulnerability
In its broadest sense, social vulnerability is one dimension of vulnerability to multiple stressors and shocks, including abuse, social exclusion and natural hazards.
