    • Natural hazard

    • A natural hazard is a natural phenomenon that might have a negative effect on people or the environment. Natural hazard events can be grouped into two broad categories. Geophysical hazards encompass geological and meteorological phenomena such as earthquakes, volcanic eruption, wildfire, cyclonic storms, flood, drought ... Read »

    • 100-year flood

    • A one-hundred-year flood is a flood event that has a 1% probability of occurring in any given year. The 100-year flood is also referred to as the 1% flood, since its annual exceedance probability is 1%. For river systems, the 100-year flood is generally expressed as a flowrate. Based on the expected 100-year flood flow ... Read »

    • Burned area emergency response

    • Burned area emergency response (BAER) is an emergency risk management reaction to post wildfire conditions that pose risks to human life and property or could further destabilize or degrade the burned lands. Even though wildfires are natural events, the presence of people and man-made structures in and adjacent to the ... Read »

    • Catastrophe modeling

    • Catastrophe modeling (also known as cat modeling) is the process of using computer-assisted calculations to estimate the losses that could be sustained due to a catastrophic event such as a hurricane or earthquake. Cat modeling is especially applicable to analyzing risks in the insurance industry and is at the confluen ... Read »

    • Defensible space (fire control)

    • Defensible Space, (sometimes called 'firescaping'), in the context of fire control, is a natural and/or landscaped area, around a structure, that has been maintained and designed to reduce fire danger. The practice is sometimes called 'Firescaping'. "Defensible space" is also used in the context of wildfires, especiall ... Read »

    • Extreme weather

    • Extreme weather includes unexpectable, unusual, unpredictable severe or unseasonal weather; weather at the extremes of the historical distribution—the range that has been seen in the past. Often, extreme events are based on a location’s recorded weather history and defined as lying in the most unusual ten per ... Read »

    • Flood risk assessment

    • A flood risk assessment (FRA) is an assessment of the risk of flooding from all flooding mechanisms, the identification of flood mitigation measures and should provide advice on actions to be taken before and during a flood. The sources of water which produce floods include: For each of the sources of water, differen ... Read »

    • Near-Earth supernova

    • A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs (30 to 1000 light-years) away) to have noticeable effects on its biosphere. On average, a supernova explosion occurs within 10 parsecs (33 light-years) of the Eart ... Read »

    • Tsunamis in lakes

    • A tsunami is defined as a series of water waves caused by the displacement of a large volume of a body of water, such as an ocean. This is misleading as destructive water waves are not restricted to the ocean, in the case of this article the body of water being investigated will be a lake rather than an ocean. Tsunamis ...
