Volcano Structure Diagram - Layers, Magma Chamber, and Eruption Process #1631311 (License: Personal Use)

This black-and-white line diagram depicts a stratovolcano in vertical cross-section, identifying major components: the magma chamber (F) at the base, the central conduit (B), and surface lava flows (L). An inset shows the eruptive plume with ash and pyroclastic material, while detached lobes on the right represent secondary lava flows or volcanic bombs. Labels highlight structural zones critical to understanding volcanic activity and hazard modeling.

Used in earth science education, geology textbooks, museum exhibits, and online learning modules to explain volcanic anatomy and eruption mechanics; matches user intent for academic study, lesson planning, or科普 content creation.
