To assess your vulnerability to the threat of a Winter Storm or Extreme Cold event to your family and property, perform an assessment to determine if you have knowledge of, are prepared and/or have a plan by answering certain questions.
Storm surge is a very complex phenomenon because it is sensitive to the slightest changes in storm intensity, forward speed, size (radius of maximum winds-RMW), angle of approach to the coast, central pressure (minimal contribution in comparison to the wind), and the shape and characteristics of coastal features such as bays and estuaries.
Ignition of a wildfire may come from a lightning strike or, more frequently, one of many possible human sources (most often arson or debris burns). Once a fire has started, certain conditions influence its behavior and homeowner risk is based on nearby land use, vegetation near homes and building design and materials.
Volcanic eruptions are most likely to occur in the Pacific Rim states and the danger area around a volcano covers approximately a 20-mile radius, although there is some danger to people within 100 miles or more. Airborne ash from a volcano can affect people hundreds of miles away from the eruption.
The largest source region for tsunamis is in the Pacific Ocean with 71% of all occurrences. The remaining occurrences of tsunamis happen in the Mediterranean Sea (15%), Caribbean Sea and Atlantic Ocean (7%), Indian Ocean (6%), and finally the Black Sea (1%). Of all tsunamis, 83% are produced directly by earthquakes.
Terrorists seek to weaken a hated political authority that is responsible — in their eyes — for illegitimate policies and/or rule. They rely on the use and threat of violence. Like crime, but unlike war, their actions are totally illegal.
Severe Thunderstorm vulnerability depends on the incidence of and societal exposure to them for a particular location. The greatest potential for severe weather develops in geographical regions that are subject to warm, humid air at low levels, while dry, conditionally unstable air prevails aloft and are most likely to occur in the spring and summer and during the afternoon and evening.
To assess your vulnerability to the threat of a Nuclear Plant Incident to your family and property, perform an assessment to determine if you have knowledge of, are prepared and/or have a plan by answering certain questions.
Assess your vulnerability to the threat of a Landslide/Mass Movement to your family and property, perform an assessment to determine if you have knowledge of, are prepared and/or have a plan.
You and your community are at risk if a chemical is used unsafely or released in harmful amounts into the environment where you live, work or play. Hazardous materials come in the form of explosives, flammable and combustible substances, poisons and radioactive materials. These substances are most often released as a result of transportation accidents or because of chemical accidents in plants.
Excessive heat events (EHEs) are and will continue to be a fact of life in the United States. Distinct groups within the population, generally those who are older, very young, or poor, or have physical challenges or mental impairments, are at elevated risk for experiencing EHE-attributable health problems.
Levels of earthquake preparedness and disaster resilience determine how vulnerable people are to seismic hazards. In any geographic area, three main factors together determine earthquake hazard vulnerability: the strength and/or duration of the seismic hazard, the proximity of people and property are to the hazard, and the number of people and amount of property that are exposed to the hazard.
One in three Americans is at risk of a poison gas disaster by living near one of hundreds of chemical facilities that store and use highly toxic chemicals. A chemical disaster at just one of these facilities could kill or injure thousands of people with acute poisoning
