Trends in Security Information
The HSD Trendmonitor is designed to provide access to relevant content on various subjects in the safety and security domain, to identify relevant developments and to connect knowledge and organisations. The safety and security domain encompasses a vast number of subjects. Four relevant taxonomies (type of threat or opportunity, victim, source of threat and domain of application) have been constructed in order to visualize all of these subjects. The taxonomies and related category descriptions have been carefully composed according to other taxonomies, European and international standards and our own expertise.
In order to identify safety and security related trends, relevant reports and HSD news articles are continuously scanned, analysed and classified by hand according to the four taxonomies. This results in a wide array of observations, which we call ‘Trend Snippets’. Multiple Trend Snippets combined can provide insights into safety and security trends. The size of the circles shows the relative weight of the topic, the filters can be used to further select the most relevant content for you. If you have an addition, question or remark, drop us a line at info@securitydelta.nl.

Explosion
An explosion is a chemical or nuclear reaction, followed by a rapid expansion in volume. An explosion can for example be caused by a bomb, rocket, missile or natural pressure build up. An explosion produces shock waves, loud noise, heat and light. A bomb is an explosive weapon that uses the exothermic reaction of explosive material to provide an extremely sudden and violent release of energy. Bombs can have a variety of delivery mechanisms, including be dropped from the air or by missile, attached to a car or a boat, delivered by a robot or drone, left behind or attached to for example a suicide vest.
There are several types of bombs, including chemical, biological and radiological bombs. In a dirty bomb, conventional explosives are combined with radioactive material. The radiation is often not enough to cause severe illness or death as is the case with a nuclear explosion. With a nuclear explosion, a single bomb has the potential to destroy an entire city, kill millions and contaminate air, land and water for many kilometres surrounding the original blast site. A bomb can be triggered by wire, radio, mobile signal or otherwise. Countermeasures depend on the delivery mechanism, type of bomb and type of trigger.
