Shield, Stratovolcano, Cinder cone. Here are some of the most popular ways students use Volcano Type Identifier every day:
Volcanoes come in strikingly different shapes and erupt in wildly different styles—but understanding why requires knowing the relationship between magma composition, viscosity, and eruption type. Applaa's Volcano Type Identifier transforms you into a volcanologist by teaching you the three main types: shield volcanoes (gentle slopes, fluid lava, Hawaii and Iceland); stratovolcanoes (steep cones, explosive eruptions, like Mount Fuji and Mount Vesuvius); and cinder cones (small, single eruption, often found clustered). This tool covers KS3 plate tectonics, GCSE Earth & Space volcanoes and hazards, and A-Level geography volcanic systems. Input magma composition (silica content), temperature, and gas content, and the tool predicts which volcano type will form and what kind of eruption to expect. See stunning photographs of real volcanoes, learn their formation history, and understand why a shield volcano in Hawaii flows gently while a stratovolcano in the Philippines explodes with pyroclastic flows. Grasp the science behind volcanic hazards and why predicting eruptions saves lives.
Answer the tool's guided questions about the magma: How much silica (SiO₂) does it contain? Is it hot or cool? Does it have lots of dissolved gas? These properties determine viscosity (thickness) and explosiveness. High-silica, cooler magma is thick and traps gas, leading to explosive eruptions and stratovolcanoes. Low-silica, hotter magma is fluid and releases gas easily, leading to gentle eruptions and shield volcanoes. Input these properties and the tool identifies the volcano type, shows you real examples (e.g. Stromboli is a stratovolcano, Mauna Loa is a shield), and predicts hazards: lava flows, pyroclastic flows, lahars, or ash columns. See cross-sections showing magma chambers, compare volcano shapes visually, and understand why Hawaiian volcanoes look completely different from Japanese ones.
The most ruinous error is assuming all volcanoes are the same—students lump them together and fail to predict hazards correctly. Stratovolcanoes are FAR more dangerous than shield volcanoes; a pyroclastic flow from a stratovolcano travels at 200+ km/h and incinerates everything in its path, while a shield volcano's lava flows at walking speed, giving days to evacuate. Another trap: forgetting that magma composition is fixed by geology, not choice; you cannot 'make' a shield volcano explode explosively—it's geologically impossible. Confusing volcanic arc (formed by subduction) with hotspot (formed by mantle plume) also costs marks on exams.

Because Vesuvius is a stratovolcano with high-silica, thick magma that traps gas and erupts explosively, creating pyroclastic flows that kill instantly. Hawaiian volcanoes are shield volcanoes with low-silica, thin magma that flows gently and releases gas easily—lava moves slowly, giving people time to evacuate. The tool shows these differences visually.
Usually yes—a tall, steep cone is almost certainly a stratovolcano (explosive). A broad, gently sloping dome is a shield volcano (gentle). But shape alone isn't diagnostic; the tool uses magma composition and location to confirm. A small, symmetrical cone might be a cinder cone (single eruption), not a stratovolcano.
No—most do (subduction zones produce stratovolcanoes; mid-ocean ridges produce shield volcanoes). But hotspots, like Hawaii, occur in plate interiors, far from boundaries. The tool shows both types and explains why geology differs in each setting.
Both—GCSE introduces volcano types and hazards; A-Level extends this to plate tectonics, magma generation, and volcanic systems over geological time. The tool covers both levels, so you'll use it in GCSE and find it equally valuable in A-Level geography and geology.
