IPA: /ˌvɒl.kəˈnɒl.ə.dʒi/
KK: /vɑlˈkɑnəˌlədʒi/
The branch of science that focuses on studying volcanoes and the processes related to them.
Volcanology helps us understand how volcanoes work and predict eruptions.
Volcanology is formed from "volcanus" (from Latin, meaning volcano) and "-logy" (from Greek "logia", meaning study or discourse). The word refers to the study of volcanoes and volcanic phenomena.
Think of 'volcanus' as relating to volcanoes and '-logy' as the study of something, so volcanology is the study of volcanoes.
