Andreas KarakonstantisDear colleagues, we look forward to receiving submissions in @FrontEarthSci (Frontiers - Earth Science) covering different areas of geoscience (#petrology, #geochemistry, #seismology).
The aim of this Research Topic is to explore the #volcanichazard near these areas using different methods, investigate current forecasting approaches, and highlight the importance of an exposure map outcome in order to produce an ameliorated volcanic risk assessment.

Volcanic Hazard Assessment Near Megacities
Volcanic hazard assessment and forecasting of upcoming eruptions is based on the record of past eruptions on various time scales, integrated with the results of volcano surveillance. More recent historical eruptions are often documented by observation, through scientific instruments, and/or eyewitness reports. Such information facilitates the understanding of the processβs systematics at individual volcanic centers or in broader areas. Megacities are typically defined as metropolitan areas with more than ten million inhabitants. They tend to occupy large areas; given a comparable hazard setting, they are statistically more likely to get affected by an event than smaller cities or even rural communities. The high growth dynamics, development speed, and the dense distribution of administrative and economic functions can lead to risks that extend to the national level. Cities near active volcanic chains, such as Manila, Mexico City, and Jakarta, urge close monitoring and detailed volcanic hazard assessment. A proper record of detailed demographic changes combined with the various types of volcanic hazards near megacities plays a vital role in the effective response of the civil authorities, minimizing possible casualties and the economic impact of an eruptive episode. For an all-encompassing hazard assessment, the main components that are taken into consideration are:β’ The typical style and magnitude of the eruptions;β’ The probability of occurrence of such an event;β’ And the ...
