A significant number of the world’s active volcanoes are unmonitored by ground-based sensors, yet constitute an important hazard to nearby residents and infrastructure, as well as air travel and global commerce.  Less than 35% of the volcanoes that have erupted since 1500 AD have continuous ground monitoring.  Data from an international constellation of more than 50 current satellite instruments provide a cost-effective means of tracking activity at such volcanoes around the world and potentially forecasting hazards.  These data span the electromagnetic spectrum -- ultraviolet, optical, infrared, and microwave (synthetic aperture radar--SAR) -- and can measure volcanic gas and thermal emissions, ground displacements, as well as surface and topographic change.  Satellites offer the unique potential to globally monitor all ~1414 subaerial volcanoes with a common set of instruments that can address one of the grand challenges in volcanology -- to overcome our current biased understanding of the relation between volcanic unrest and eruption based on only a few well-studied volcanoes.
