History has shown that successful volcanic risk and crisis management strongly correlates with proactive risk reduction policies and practice being in place before a volcanic crisis begins. Such policies and practice should ideally be co-developed by scientists and stakeholders based on comprehensive understanding and analysis of the volcanic risk that encompass the characterization of elements at risk and the full spectrum of vulnerability types associated with volcanic hazards. Volcanic risk assessments and related products and services are useful for decision makers such as national and local civil protection organization authorities before the event (long term), during the event (short term) and after the event (long-term). The UN Sendai Framework for Disaster Risk Reduction (SFDRR) recognizes that national and federal authorities have the primary role to reduce disaster risk; however local governments, communities, the private sector and other stakeholders need to be involved in the process. Hence, comprehensive and effective risk assessments and related products and services should be co-designed and co-produced by scientists and stakeholders to answer specific needs and to enhance preparedness for effective response (e.g. SFDRR Priority 4). We welcome contributions presenting innovative strategies and good practice on how volcanic risk assessments and related products and services facilitate real-time decision-making processes, improve emergency planning for future events, development of early warning systems and resilience action planning. Contributions describing the main challenges communicating risk to the public and local authorities are also invited.
