Man-made disasters are the result of human intent, error, or as a result of failed systems. They can be divided into categories such as terrorism, technological hazards, transportation hazards and environmental accidents.

  • Terrorism is defined as an act that is violent or dangerous to human life, with the intent of furthering political or social objectives. The threat of terrorism affects all communities around the world.  Terrorists, both Domestic and International, have demonstrated they have the knowledge and capability to strike anywhere in the world.
  • Domestic Terrorism involves groups or individuals whose terrorist activities are directed at elements of our government or population without foreign direction.
  • International Terrorism involves groups or individuals whose terrorist activities are foreign-based and/or directed by countries or groups outside the United States or whose activities transcend national boundaries.

Weapons of Mass Destruction

The term Weapons of Mass Destruction (WMD) is often used to refer to the group of threats consisting of chemical or biological agents, or radiological, nuclear, or explosive devices (CBRNE). These are weapons that have a relatively large-scale impact on people, property, and/or infrastructure. Information on WMDs can be found here  or below in the threat-specific pages.

National Terrorism Advisory System

The National Terrorism Advisory System (NTAS)  is the structure used in the United States to communicate terrorist threats. This system effectively relays timely, detailed information to the public, government agencies, first responders, airports, transportation hubs and the private sector. NTAS replaces the color-coded Homeland Security Advisory System (HSAS).

NTAS, which is run through the Department of Homeland Security, recognizes that Americans all share responsibility in the nation's security, and should always be aware of the heightened risk of terrorist attack in the United States. The NTAS website provides current and expired alerts as well as a sample NTAS alert.

Explosions can occur by accident or as the result of malicious intent. Bombs, explosives or other incendiary devices are one of the most common methods used by terrorists to inflict harm and create fear.  Although the purpose behind many bombs is to cause harm and destruction through an explosion, bombs can also be used to disperse chemical, biological, incendiary and nuclear agents. This link  will provide you with more information.

A chemical emergency occurs when a hazardous chemical (gas, liquid or solid) has been released and the release has the potential for harming people’s health. Chemical releases can be unintentional, as in the case of an industrial accident, or intentional, as in the case of a terrorist attack.
