Based on the above, a critical review of the current state of knowledge on the distribution of the different types of hazards occurring on Ischia is presented. This is accomplished by a spatial analysis of volcanic and seismic events (SDEs) up to 1991, focusing on the distribution of both the T and E Hazard Categories (T&E). At the same time, an assessment of the hazards related to the non-eruptive volcanic phenomena is also addressed, since earthquakes and PDCs are typically characterized by a limited spatial extent and/or very short recurrence time. The analysis is conducted by interpreting the information in the present-day distribution of the different hazards on the basis of the spatial and temporal characteristics of the phenomena generating those hazards. As a result of the analysis, a hazard map for Ischia is created, where each area of the map is characterised by one main hazard (eruptive, non-eruptive, or both) and each cell is associated to a specific hazard category. In this context, it is assumed that an area with a higher intensity of a hazard will have a higher likelihood of occurrence than an area with a lower intensity of the same hazard. However, we are aware that the mapping of hazards does not provide a measure of the risk of occurrence.
Owing to the multi-causality, MRC episodes are quite complex phenomena. We must distinguish between the interaction between hydrothermal systems, ground deformation and related volcanic activity (e.g., effusive eruptions, ignimbrite, lava flows, hydrothermal explosions). The episodic progression is influenced by: i) the physical and chemical (hydrogen isotopes, composition, and osmotic pressure) properties of the fluids involved (e.g., ground water, hydrothermal fluids); ii) the surface orientation and roughness; iii) the internal state and driving process of fluids (pressure, flow-rate, temperature, and composition); iv) the presence of rocks and/or sediments with potential lower permeability (e.g., coal- and shale-units); v) the closeness of interaction of hydrothermal systems to the tectonic setting (e.g.
