The main aim of this WG is to promote the international collaboration among national landslide early warning systems operational and/or in a development stage, by discussing common strengths and limitations and by providing examples of best practices and lessons learned (especially under certain particular weather conditions). The WG aims also to prepare general guidelines of requirements for the organization, operation, maintenance, and periodic evaluation of the systems.
