Improving global multi-hazard arrangements for volcanic eruptions

If we are serious about multi-hazard early warning systems, we need to address shortcomings in our global structures, for example with volcanoes. Volcanoes produce many different natural hazards that cross-disciplines and borders. Unlike in hydrometeorology, which has the World Meteorological Organization with clear responsibility for international coordination, there is no UN treaty level organization tasked to assist the world’s volcano observatories in running a globally coordinated system. This is a fixable problem and addressing it would provide great benefits.
