ABSTRACT

The problem of monitoring the consequences of volcanic activity for landresources remains underdeveloped, while existing systems are focused primarily on eruption forecasting. The aim of the study was to develop a comprehensive system of controlled indicators for assessing land conditions in areas of active volcanism. Based on a retrospective analysis of eruption impacts, remote sensing data, and fieldresearch, a system of controlled indicators was created. This system includes key quantitative metrics such as the area of impact, proportion of damaged vegetation and soil cover, normalized difference vegetation index anomaly, deposit thickness, and infrastructure damage level. A scale of the degree of development of the negative process with three grades (severe, moderate, weak) was developed based on the system of indicators. This scale uses threshold values for the disturbance of soil and vegetation cover (70% and 30%). The proposed system enables a transition from descriptive assessments to standardized quantitative monitoring, forming a basis for state land monitoring, land zoning, and planning restoration measures in volcanically active regions.
