There are several different types of volcanoes in the world, varying in form and activity level. The Hawaiian volcanoes are a well known group among scientists and visitors from around the world. Kilauea, in particular, is renowned as one of the most active volcanoes on Earth. 

So, what type of volcano is Kilauea? Let’s explore a bit more about shield volcanoes and specific characteristics of Kilauea. 

Shield Volcanoes in Hawaii

Haleakala is a famous Hawaiian shield volcano that forms Maui.

The volcanoes in Hawaii were created by an active hotspot and formed from basaltic lava. Basalt is a type of lava that is very fluid when released in eruptions, and is commonly found at volcanic hotspots. These volcanoes fall into the category of shield volcanoes.

Shield volcanoes are among the largest volcanoes on Earth. The Hawaiian volcanoes, such as Kilauea and Mauna Loa, are the most famous examples of this particular type.

Shield volcanoes aren’t steep. They have a flatter, more rounded shape as the lava is very fluid and can flow quickly over large distances. The eruptions are generally characterized by ‘low-explosivity fountaining’ of lava. The fact that visitors can get up close to lava flows to take pictures and explore hints at the fact that people can easily outrun this lava. It typically isn’t of immediate danger.

Explosive eruptions do sometimes occur, but they tend to be infrequent. Water that seeps into the vents can cause explosive eruptions. The broad profile created by the more gentle eruptions and lava flows resembles the shape of a shield lying on the earth.

Characteristics of Kilauea

kilauea shield volcanoKilauea is the youngest and most active volcano on the Big Island. It sits to the Southeast of the largest shield volcano, Mauna Loa. Currently, Kilauea has been in a continual state of eruption since 1983. As a result, the volcano is on its way to become the longest eruption known on Earth. Scientists have documented the activities of Kilauea since the 1820s. The eruptions also play a large role in shaping Hawaiian legends.

At the summit of Kilauea, there is a large caldera with a central pit crater, named Halemaumau. According to Hawaiian legends, Halemaumau is the home of Pele, the goddess of fire. A caldera is a large, bowl-shaped volcanic depression that forms when the volcano collapses into itself. This is usually the result of a large eruption that empties the magma chamber beneath it. The Kilauea caldera is three kilometers by five kilometers, and formed in stages around 15,000 years ago.

Due to frequent volcanic activity, around 90% of Kilauea consists of lava flows that are less than 1,100 years old. In addition, 70% of the surface is under 600 years old. The eruption that started in 1983 is in the East Rift Zone. It has caused many lava flows covering an area of 100 square kilometers, and destruction to over 200 homes and buildings. Lava flowing to the ocean has added new coastline to the island. 

Kilauea is a prime example of an active shield volcano made of basalt lava that also has the characteristic shield shape. The youngest on the island, it is the most active volcano in the world.
