Stratovolcanoes, also known as composite volcanoes, are recognized for their explosive eruptions due to several key characteristics. These volcanoes are typically formed from a mixture of thick, viscous magma that is more capable of trapping gases compared to the fluid lava found in shield volcanoes. As pressure builds up within the volcano from the gases, it can lead to highly explosive eruptions when the magma finally makes its way to the surface.

The structure of stratovolcanoes is another factor contributing to their explosive nature. They are composed of multiple layers of hardened lava, tephra, and ash, creating steep profiles. During eruptions, these volcanoes can produce large amounts of ash and pyroclastic flows, which are fast-moving currents of hot gas and volcanic matter. Such explosive activity makes stratovolcanoes among the most dangerous volcano types.

In contrast, shield volcanoes are built from fluid lava flows that travel long distances, resulting in gentle slopes and non-explosive eruptions. Fissure volcanoes typically erupt from cracks in the ground and produce basaltic lava flows, leading to a more effusive eruption style. Dome volcanoes, on the other hand, feature thick lava that piles up near the vent, leading to
