shield volcanoes are only explosive if water somehow gets into the vent
Hawaii has shield volcanoes, which are broad, gently sloping volcanoes characterized by eruptions of relatively fluid lava that creates a wide base. These volcanoes are formed by repeated eruptions of low viscosity basaltic magma.

A broad volcano with gently sloping sides describes a shield volcano. These types of volcanoes are characterized by their low, wide profile and are formed by the slow accumulation of fluid lava flows over time, which create a shield-like shape. This type of volcano tends to have non-explosive eruptions due to the low viscosity of the lava.
It was formed by a neighbouring volcano called Chato. The successive eruptions from Chato formed Arenal.
Explosive eruptions will produce pyroclastic rocks such as scoria, pumice, and tuff.
Diagram 1: Stratovolcano (composite volcano) - Formed by layers of ash, lava, and volcanic rocks building up over time. Diagram 2: Shield volcano - Formed by repeated eruptions of low-viscosity basaltic lava, which spreads out in thin layers, creating a wide, gently sloping shape.
A shield volcano is a very large, gently sloping mound composed mainly of basaltic lava flows. These volcanoes have a broad, dome-like shape and their eruptions are typically non-explosive. Examples include Mauna Loa in Hawaii and Galapagos Islands.
