Summary

The study of volcanic activity is a critical field of research with direct applications in the prediction of volcanic eruptions and the mitigation of risks to human life and the environment. Volcanoes are dynamic geological systems whose activity is associated with complex geophysical and geochemical mechanisms. One of the most significant indicators of a potential eruption is increased seismic activity, which is caused by magma movement and changes in the geological conditions within the Earth. At the same time, variations in surface or subsurface temperature may serve as an indication of intensified volcanic activity.The aim of this thesis is to investigate the relationship between seismic activity and temperature variations using statistical methods and data analysis techniques. Specifically, it examines whether changes in temperature can act as a precursor indicator of volcanic activity, in conjunction with seismic fluctuations, and to what extent the statistical processing of data can contribute to the development of volcanic eruption prediction models. The analysis is based on historical temperature and seismic data from volcanic regions, with a focus on the case of the Eyjafjallajökull volcano in Iceland, whose 2010 eruption was one of the most significant volcanic events in recent decades.This study aspires to contribute to a better understanding of the dynamics of volcanic systems and to the development of improved predictive tools that can assist in implementing protective measures for populations living in volcanic areas.
