About this Research Topic
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 process’s 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:
• The typical style and magnitude of the eruptions;
• The probability of occurrence of such an event;
• And the current activity of the monitored volcanic center.
Investigating the volcanic hazard in these areas is vital for decision-makers in order for the Civil Authorities to have better territorial management and future planning in case of emergencies. Mitigation measures informed by hazard assessment provide the potential to reduce the exposure. The increasing impact of sharing such information on social media platforms is essential in connecting the science community with the local populations exposed to such hazards, which plays a vital role in risk reduction.
The aim of this Research Topic is to explore the volcanic hazard 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 for future studies.
We look forward to receiving submissions covering the different aspects of this topic from a variety of geoscience fields (petrology, geochemistry, seismology), using different approaches that lead to the amelioration of the result and their insights in the interconnection of such studies to disaster risk minimization and collaboration with the civil authorities of each country/region.
