The Troubles The Troubles (Irish: "Na Trioblóidí" ) was an ethno-nationalist conflict in Northern Ireland during the late 20th century. Also known internationally as the Northern Ireland conflict, it is sometimes described as a "guerrilla war" or a "low-level war". The conflict began in the late 1960s and it is usually deemed to have ended with the Good Friday Agreement of 1998. Although the Troubles mainly took place in Northern Ireland, at times the violence spilled over into parts of the Republic of Ireland, England and mainland Europe.
Explosive train A triggering sequence, also called an explosive train, is a sequence of events that culminates in the detonation of explosives. For safety reasons, most widely used high explosives are difficult to detonate. A primary explosive of higher sensitivity is used to trigger a uniform and predictable detonation of the main body of the explosive. Although the primary explosive itself is generally a more sensitive and expensive compound, it is only used in small quantities and in relatively safely packaged forms. By design there are low explosives and high explosives made such that the low explosives are highly sensitive (i.e. their 'Figure of Insensitivity' is low) and high explosives are comparatively insensitive. This not only affords inherent safety to the usage of explosives during handling and transport, but also necessitates an explosive triggering sequence or explosive train. The explosive triggering sequence or the explosive train essentially consists of an 'initiator', an 'intermediary' and the 'high explosive'.
