TYPES OF DISASTERS

NATURAL DISASTERS

Hurricane
Hurricanes are dangerous and destructive. It is also known as cyclones and typhoons in other parts of the world, hurricanes cause high winds, flooding, heavy rain, and storm surges (high tidal waves). 
​​
In most situations, you will reduce your chance of injury from falling objects (and even building collapse) if you immediately:

Earthquake
Earthquakes are sudden rolling or shaking events caused by movement under the earth’s surface. Earthquakes happen along cracks in the earth's surface, called fault lines, and can be felt over large areas, although they usually last less than one minute.
Earthquakes cannot be predicted!  All 50 states are at some risk for earthquakes.  Earthquakes can happen at any time of the year.
 
Tsunami
Tsunamis, also known as seismic sea waves (mistakenly called “tidal waves”), are a series of enormous waves created by an underwater disturbance such as an earthquake, landslide, volcanic eruption, or meteorite. 


Flood
Floods, big or small, can have devastating effects on your home and your family. You can take steps to reduce the harm caused by flooding.  

Wildfires
More and more people live in areas that are prone to wildfires. You can take steps to be ready for a wildfire and prepare your home and landscaping to reduce your risk.

Landslide
Landslides occur when masses of rock, earth, or debris move down a slope. Debris flows, also known as mudslides, are a common type of fast-moving landslide that tends to flow in channels.


Natural disasters are extreme, sudden events caused by environmental factors that injure people and damage property.  The natural disasters listed above are just a handful of disasters that threaten the Wai'anae Coast. Other natural disasters that may threaten the Wai'anae Coast are drought, storm surges, thunder storms, high winds, and erosion. Most natural disasters can strike at anytime with little or no warning.

MAN-MADE DISASTERS

Active Shooter
An active shooter is an individual actively engaged in killing or attempting to kill people in a confined or populated area; in most cases, active shooters use firearm(s) and there is no pattern or method to their selection of victims.

Active shooter situations are unpredictable, often occur without warning and evolve quickly. Typically, the immediate deployment of law enforcement is required to stop the shooting and mitigate harm.

Explosives
Terrorists have frequently used explosive devices as one of their most common weapons. Terrorists do not have to look far to find out how to make explosive devices; the information is readily available in books and other information sources. Explosive devices can be highly portable, using vehicles and humans as a means of transport. They are easily detonated from remote locations or by suicide bombers.

Power Outages
Most common reasons for power outages are power equipment failure, storms, wildlife, tree limbs, public damage, and overloading of the electricity main.

Power outages are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, mines, shelters and the like will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost.

Chemical, Biological, Radiological, and Nuclear (CBRN)
Chemical agents are poisonous vapors, aerosols, liquids and solids that have toxic effects on people, animals or plants. They can be released by bombs or sprayed from aircraft, boats and vehicles.

Biological agents are organisms or toxins that can kill or incapacitate people, livestock and crops. A biological attack is the deliberate release of germs, bacteria, viruses or toxins that can make you sick.

Terrorist use of a Radiological Dispersion Device (RDD) — often called “dirty nuke” or “dirty bomb” — is considered far more likely than use of a nuclear explosive device. An RDD combines a conventional explosive device — such as a bomb — with radioactive material.

A nuclear blast is an explosion with intense light and heat, a damaging pressure wave, and widespread radioactive material that can contaminate the air, water, and ground surfaces for miles around. A nuclear device can range from a weapon carried by an intercontinental missile launched by a hostile nation or terrorist organization, to a small portable nuclear device transported by an individual.

Man-made disasters are disastrous events caused directly by one or more identifiable deliberate or negligent human actions that cause injury to people and damage to property.  The man-made disasters listed above are just a handful of disasters that may threaten the Wai'anae Coast community. Other man-made disasters that may threaten the Wai'anae Coast are cyber attacks, hazardous materials, and pandemic. Most man-made disasters strike at anytime, often without warning
