The program will include some sessions focused on the geochemical and hydrogeochemical characterization of lake waters, to better understand some processes that may be affecting these water bodies, and also, on the interaction of the lake water masses in volcanic environments. A special session on the Azores lakes will be part of the program. Characterization of the Azorean secondary manifestations of volcanism will also be included in this section. The main topics will be:

​

• Geochemical and geophysical studies of volcanic lakes;

• Gaseous emissions from lakes;

• The impact of volcanic lakes on society;

• Volcanic lake monitoring;

• Hazard assessment;

• Phreatic events.
