## What is SnT2021?

The SnT2021 App provides easy access to relevant information about the CTBT Science and Technology Conference 2021. It contains the list of participants, speaker profiles, programme, abstracts and other useful information related to this particular event. It also includes voting, announcements, social walls and other functions as well as a built-in messaging service which allows participants to communicate with each other.

The CTBT bans all nuclear explosions everywhere, by everyone, and for all times. A verification regime to monitor the globe for nuclear explosions is nearing completion with around 92 percent of the 337 planned International Monitoring System facilities already in operation, ensuring that no nuclear explosion goes undetected. The data registered by the IMS can also be used for disaster mitigation such as earthquake monitoring, tsunami warning, and the tracking of the levels and dispersal of radioactivity from nuclear accidents.

CTBTO's multidisciplinary conferences attract scientists and experts from the broad range of the CTBT's verification technologies, from national agencies involved in the CTBTO's work to independent academic and research institutions, as well as policy makers. Members of the diplomatic community, international media and civil society also take an active interest.
