Investigating active volcanoes through remote sensing and teaching geography students how to analyze spatial images

This article deals with two aspects of the study of active volcanoes: 1) the role of remote sensing in investigating active volcanoes; 2) teaching geography students how to analyze spatial images of active volcanoes.
As far as the role of remote sensing in investigating active volcanoes is concerned, we will be examining the following aspects: the morphology of active volcanoes, with the changes that occur after each eruptive episode; identifying the signs that precede a volcanic eruption; monitoring volcanic eruptions and their impact on the environment and on the natural habitat.
Regarding the methods used to teach geography students how to analyze, in laboratory conditions, satellite images of active volcanoes (of areas with active volcanoes), the present article includes computer-aided demonstrations performed on different categories of images (visible, thermal infrared, radar, composite, 3D) and of volcanoes. The aim of these demonstrations is to prove the importance of satellite data in investigating active volcanoes and their relationship with the environment, as well as the fact that geography students should learn and apply appropriate methods in analyzing satellite images.
