Composite Volcano Structure Diagram - Anatomy of a Stratovolcano #1810062 (License: Personal Use)

This annotated diagram illustrates the layered internal architecture of a composite volcano, including the magma chamber, conduit, branch pipes, sill, dike, parasitic cone, flank, side vent, summit, throat, crater, and eruptive products like lava flows and ash clouds. The stratified rock layers represent alternating deposits of lava and pyroclastic material, characteristic of explosive and effusive eruptions over time. Labels highlight both subsurface plumbing and surface features critical to understanding volcanic hazards.

Used in educational contexts-geology textbooks, science websites, classroom slides-to teach volcano types and eruption mechanics; matches user intent for visual learning, academic study, or curriculum development.
