A natural hazard[1] is a threat of a naturally Nature, in the broadest sense, is equivalent to the natural world, physical world, or material world. "Nature" refers to the phenomena of the physical world, and also to life in general. It ranges in scale from the subatomic to the cosmic occurring event that will have a negative effect on people or the environment. Many natural hazards are interrelated, e.g. earthquakes An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Earthquakes are recorded with a seismometer, also known as a seismograph. The moment magnitude (or the related and mostly obsolete Richter magnitude) of an earthquake is conventionally reported, with magnitude 3 or lower earthquakes being can cause tsunamis A tsunami (English pronunciation: /(t)suːˈnɑːmi/) is a series of water waves (called a tsunami wave train) that is caused by the displacement of a large volume of a body of water, such as an ocean. The original Japanese term literally translates as "harbor wave." Tsunamis are a frequent occurrence in Japan; approximately 195 events and drought A drought is an extended period of months or years when a region notes a deficiency in its water supply. Generally, this occurs when a region receives consistently below average precipitation. It can have a substantial impact on the ecosystem and agriculture of the affected region. Although droughts can persist for several years, even a short, can lead directly to famine A famine is a widespread scarcity of food that may apply to any faunal species. This phenomenon is usually accompanied by regional malnutrition, starvation, epidemic, and increased mortality. A concrete example of the division between a natural hazard and a natural disaster is that the 1906 San Francisco earthquake The San Francisco earthquake of 1906 was a major earthquake that struck San Francisco, CA and the coast of Northern California at 5:12 A.M. on Wednesday, April 18, 1906. The most widely accepted estimate for the magnitude of the earthquake is a moment magnitude of 7.8; however, other values have been proposed, from 7.7 to as high as 8.25. The main was a disaster, whereas earthquakes are a hazard. A natural hazard becomes a natural disaster A natural disaster is the effect of a natural hazard 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. This understanding is concentrated in the formulation: "disasters occur when hazards when it affects people, officially causing more than 10 deaths, injuring more than 100 people, and/or causing US$16,000,000 of damage.[citation needed]
