The Emergency Broadcast System (EBS), sometimes called the Emergency Action Notification System (EANS), was an emergency warning system used in the United States. It was the most commonly used, along with the Emergency Override system. It replaced the previous CONELRAD system and was used from 1963 to 1997, at which point it was replaced by the Emergency Alert System.
CONELRAD was a method of emergency broadcasting to the public of the United States in the event of enemy attack during the Cold War. It was intended to allow continuous broadcast of civil defense information to the public using radio stations, while rapidly switching the transmitter stations to make the broadcasts unsuitable for Soviet bombers that might attempt to home in on the signals.
The Emergency Alert System (EAS) is a national warning system in the United States designed to allow authorized officials to broadcast emergency alerts and warning messages to the public via cable, satellite, or broadcast television, and both AM/FM and satellite radio. Informally, Emergency Alert System is sometimes conflated with its mobile phone counterpart Wireless Emergency Alerts (WEA), a different but related system. However, both the EAS and WEA, among other systems, are coordinated under the Integrated Public Alert and Warning System (IPAWS). The EAS, and more broadly IPAWS, allows federal, state, and local authorities to efficiently broadcast emergency alert and warning messages across multiple channels.
Protect and Survive was a public information campaign on civil defence. Produced by the British government between 1974 and 1980, it intended to advise the public on how to protect themselves during a nuclear attack. The campaign comprised a pamphlet, newspaper advertisements, radio broadcasts, and public information films. The series had originally been intended for distribution only in the event of dire national emergency, but provoked such intense public interest that the pamphlet was published, in slightly amended form, in 1980. Due to its controversial subject, and the nature of its publication, the cultural impact of Protect and Survive was greater and longer-lasting than most public information campaigns.
Continuity of government (COG) is the principle of establishing defined procedures that allow a government to continue its essential operations in case of a catastrophic event such as nuclear war.
The BBC Home Service was a national and regional radio station that broadcast from 1939 until 1967, when it was replaced by BBC Radio 4.
The Diefenbunker, formerly known by its military designation, Canadian Forces Station Carp (CFS Carp), is a large underground four-storey reinforced concrete bunker and nuclear fallout shelter located in the rural area of Carp, Ontario approximately 30 km (19 mi) west of downtown Ottawa. Between 1957 and 1961, during the Cold War the Government of Canada led by then Prime Minister John Diefenbaker authorized the Diefenbunker to be designed and built as the Central Emergency Government Headquarters (CEGHQ Carp) in an attempt to ensure the continuity of government subsequent to a nuclear weapons attack by the Soviet Union. In 1994, CFS Carp was decommissioned and closed.
The four-minute warning was a public alert system conceived by the British Government during the Cold War and operated between 1953 and 1992. The name derived from the approximate length of time from the point at which a Soviet nuclear missile attack against the United Kingdom could be confirmed and the impact of those missiles on their targets. The population was to be notified by means of air raid sirens, television and radio, and urged to seek cover immediately. In practice, the warning would have been more likely three minutes or less.
An emergency population warning is a method where by local, regional, or national authorities can contact members of the public to warn them of an impending emergency. These warnings may be necessary for a number of reasons, including:
Peter Ian Donaldson was an English newsreader on BBC Radio 4.
Wood Norton Hall is a Grade II* listed Victorian stately home to the northwest of Evesham, Worcestershire, England. It was the last home in England of Prince Philippe, Duke of Orléans, who claimed the throne of France.
The United Kingdom Warning and Monitoring Organisation (UKWMO) was a British civilian organisation operating to provide UK military and civilian authorities with data on nuclear explosions and forecasts of fallout across the country in the event of nuclear war.
The Central Government War Headquarters (CGWHQ) is a 35-acre (14 ha) complex built 120 feet (37 m) underground as the United Kingdom's emergency government war headquarters – the hub of the country's alternative seat of power outside London during a nuclear war or conflict with the Soviet Union. It is in Corsham, Wiltshire, in a former Bath stone quarry known as Spring Quarry, under the present-day MoD Corsham.
The BBC Forces Programme was a national radio station which operated from 7 January 1940 until 26 February 1944.
Transition to war (TTW) is a North Atlantic Treaty Organization (NATO) military term referring to a period of international tension during which government and society move to an open war footing. The period after this is considered to be war, conventional or otherwise, but the term TTW found its origins in the peak of the Cold War as a key NATO concept within the tripwire escalation of the DEFCON status. This could include the suspension of peacetime services, closing motorways to all but military traffic and the internment of subversives without charge or trial. The Federal Emergency Management Agency would declare this period as Increased Readiness in a move to expedite Civil Defense training and to an extent is similar to Transition to War.
WGU-20 was an emergency government civil defense preparedness radio station in Chase, Maryland USA, operated by the United States Defense Civil Preparedness Agency in the 1970s.
The Kelvedon Hatch Secret Nuclear Bunker at Kelvedon Hatch, in the Borough of Brentwood in the English county of Essex, is a large underground bunker maintained during the Cold War as a potential regional government headquarters. Since being decommissioned in 1992, the bunker has been open to the public as a tourist attraction, with a museum focusing on its Cold War history.
The Public Warning System (PWS) is a network of civil defense sirens installed by the Singapore Civil Defence Force on over 2,000 strategic points in Singapore to warn Singaporeans of impending dangers, air raids and atomic bomb blasts. Thus far, the siren network has only been used for occasional public awareness drills, monthly noon chimes and for commemorating the island's Total Defence (February 15) and Civil Defence Days (September 15). It was also used to mark a minute's silence nationwide for the passing of former prime minister Lee Kuan Yew on the evening of 23 March 2015 and on 1 and 9 August 2020 to mark the first National Day at home.
