Shield Volcano Formation
A shield volcano is a type of volcano that is formed by the eruption of low-viscosity lava that flows easily and spreads out in all directions. The lava forms a broad, gently sloping cone-shaped mountain, resembling a warrior’s shield, hence the name shield volcano. These volcanoes are typically found in areas with hot spots or along mid-oceanic ridges. The Kilauea volcano in Hawaii is a famous example of a shield volcano. Its formation is characterised by multiple eruptions over time, with each eruption adding layers of lava to the volcano’s structure. The result is a massive, shield-shaped mountain that is constantly growing and changing due to ongoing volcanic activity.
Hotspot Theory
The Hotspot Theory is a geological theory that explains the formation of volcanic islands, such as the Kilauea Volcano in Hawaii. According to this theory, a hotspot is a stationary area of intense volcanic activity beneath the Earth’s surface. As the tectonic plate moves over the hotspot, magma rises to the surface, creating a volcano. The hotspot remains in the same location, while the tectonic plate continues to move, resulting in a chain of volcanic islands. The Kilauea Volcano is one of the most active volcanoes in the world and is a prime example of the Hotspot Theory in action.
Current Status of Kilauea Volcano
