The National Terrorism Advisory System (NTAS) of the Department of Homeland Security (DHS) notifies the public and appropriate government and private sector partners about prospective or existing threats, identifying whether the danger is "imminent" or "elevated." Threat Alerts will provide information on the impacted area. Emergency Response Guides will help citizens prepare for emergencies.
What are the differences between a threat alert and an emergency response guide? A threat alert is issued when there is sufficient information to indicate that a terrorist attack may be imminent. An emergency response guide is published when there is insufficient time to issue a threat alert, but enough information is available to guide responders how to best protect themselves during an incident.
Threat alerts are released at the federal level through the DHS Office of Integrated Communications and Risk Management. These notices are sent via email to more than 6,000 recipients including state and local officials who are responsible for issuing emergency declarations. They also are posted on the NTAS website and communicated through social media platforms such as Facebook and Twitter.
Threat alerts are issued for five priority threat categories: natural disasters, man-made disasters, medical incidents, criminal acts and other elevated risks. For each category, there is a list of potential threats that can be activated by state, local, tribal, or foreign governments or non-governmental organizations.
A: NTAS advises apply to Americans living in the United States and its territories; but, as previously stated, NTAS Bulletins may address broad terrorist trends and developments, including trends and developments in other countries, that do not constitute a specific threat to the United States. Therefore, it is important for Americans to read all Bulletin announcements before they expire.
The Homeland Security Alert System in the United States was a color-coded terrorist threat advisory system. The media in the United States referred to it as the "terror alert level." On April 27, 2011, the system was replaced with a new system known as the National Terrorism Advisory System. The change was made by President Barack Obama during his daily briefing on national security issues.
It was created after the September 11 attacks to provide federal agencies with the ability to issue alerts to the public about threats to safety and security. The original system was designed to be easy to understand and use by all levels of government employees and the public. It consisted of four levels: red, yellow, green, and blue. These levels were intended to guide agency responses to threats, with red alerts indicating a serious threat requiring immediate action; yellow alerts indicating a possible threat that should be monitored closely; green alerts meaning there is no current indication of a threat; and blue alerts used to indicate minor administrative matters.
The system was revised on April 27, 2011, when President Obama issued an executive order establishing the NCTAS. The new system is based on the same four levels but uses different colors to represent them: red for highest risk; orange for high risk; yellow for moderate risk; and green for no risk. There is also a new purple alert level that can be used for extreme circumstances such as a chemical attack or other emergency situation where the use of traditional warning systems may not be feasible.
The Homeland Security Advisory System, which was established in March 2002, was created to distribute information about the danger of terrorist activities to federal, state, and local government entities, as well as the general public. The system uses an advisory format that allows for quick dissemination of important security information.
An advisory is issued when there is credible information that an incident may occur within the United States. It is not required that an attack actually take place for an advisory to be issued. Seven categories of advisories are used: national, regional, county, city/town, tribal nations, and special event. Each advisory contains both a description of the potential threat and recommendations for actions that should be taken to protect citizens from harm.
Advisories are distributed through multiple media channels, including email, social media, television, radio, and the telephone.
In addition to distributing security information, the Homeland Security Advisory System also serves as an emergency notification system. This capability is useful in cases where there is no immediate threat to life but significant damage could result if certain actions were not taken immediately to prevent loss of property or disruption of business operations.
If an incident does involve a threat to life, then officials will issue a warning. A warning reduces the likelihood of injury or death by instructing people what they should do to prepare for the incident.
A systematic national effort to prevent terrorist attacks within the United States, lessen America's susceptibility to terrorism, and mitigate and recover from assaults that do occur. The Department of Homeland Security is the federal government's principal department in charge of homeland security. It was created by Congress in 2002 after the September 11 attacks.
The Federal Bureau of Investigation (FBI) is a federal law enforcement agency that conducts investigations to protect the nation from violence, including terrorism. The FBI is part of the Department of Justice. It is charged with investigating crimes against individuals as well as acts of terrorism. The FBI's role includes criminal investigation and prevention, protection of federal facilities, cooperation with foreign governments, and training of their police forces.
The Transportation Security Administration (TSA) is a government agency responsible for aviation security at the airports.
The Office of Anti-Terrorism (OAT) is a unit within the Department of Defense (DOD) responsible for providing leadership on counterterrorism issues for the Secretary of Defense and Chairman of the Joint Chiefs of Staff. Its mission is to prevent terrorist attacks against the United States through interagency coordination and collaboration.
The National Counterterrorism Center (NCTC) is a joint United States government organization that collects information on terrorists groups around the world and shares it among federal agencies.
