Environmental Hazards, 3: 93-109. A disproportionately high number of these active volcanoes lie in less economically developed countries, where rapid urbanisation and growing populations have increased the risk of future volcanic eruptions affecting public health. Communities throughout the world continue to live within areas of active volcanism despite repeat, catastrophic eruptions, and some have developed measures to mitigate volcanic hazards, including engineering solutions, monitoring systems, evacuation plans and land-use restrictions. While these measures address the
