Kilauea is a young stage 4 basaltic shield volcano, the youngest volcano in the Hawaiian islands. It’s located on the southernmost and largest of the island chain, the Big Island of Hawai’i, about 45 miles from the city of Hilo.
Unlike many other volcanoes, which can sit dormant for many years at a time, Kilauea is almost contently erupting from vents at the caldera or from smaller surrounding rift zones.
If you’re planning a trip to Hawai’i, make sure you don’t miss the chance to see this wonder up close! Kilauea has been erupting continuously since 1983, and sees over two million visitors each year at its home in the Hawai’i Volcanoes National Park.

Like all the volcanoes in the Hawaiian islands, Kilauea formed as a result of the Pacific tectonic plate moving over the Hawaiian hotspot in the Earth’s mantle. These island volcanoes are the most recent evidence of a 70-million-year-long process which created the 3,700-mile-long Hawaiian-Emperor seamount chain.
Kilauea is widely known as the most active volcano on the Big Island, and as one of the most active volcanoes in the entire world. It’s one of the most famous on Earth due to this frequent activity.
While ‘most active’ can be tricky to say for sure, geologists don’t seem to have too much issue with putting Kilauea at the top of the list.Other competitors for the top spot are Sakurajima in Japan and Mount Etna in Sicily.
The name ‘Kilauea’ actually means “much spreading” or “spewing” in the Hawaiian language, referring to the volcano’s frequent lava outpourings. Really tells you everything you need to know about the volcano!
Even though Kilauea is the youngest of the volcanoes in the island chain, it’s not exactly a kid! The volcano is estimated to be between 210,000 and 280,000 years old. It emerged above sea level roughly 100,000 years ago.
While it is generally safe to travel to Hawai’i even with all the volcanic activity in the region, you’ll want to use some extra caution if you plan to visit Kilauea. The volcano’s home, the Hawai’i Volcanoes National Park, is open every day of the year and tours can be taken to the volcano when it is in a dormant state.
The volcano receives over two million visitors each year, so if you’re planning a trip to Hawai’i and want to get a look at this natural wonder, be prepared to navigate the crowds.
Activity at the volcano is caused by an upwelling of hot mantle which gives off enough heat to create magma underneath the volcano. This magma then has the opportunity to erupt through a number of different vents around the caldera.
Its activity level is also helped along by the fact that the region is a volcanic hotspot, seeing much more activity on average than the surrounding areas.
Kilauea’s elevation is measured at 4,091 feet above sea level. Unlike stereotypical volcanoes, which are a mountain-like structure with a clear top, Kilauea is more spread out. It has a main caldera as well as around two dozen smaller craters in the surrounding rift zones, which frequently erupt as well.
For comparison, the tallest volcano in the Hawaiian islands is Mauna Kea, which stands at 13,803 feet above sea level.
Kilauea is a basaltic shield volcano. It erupts a type of basalt called tholeiite, the dominant basalt type erupted on Earth. This makes Kilauea a fairly common volcano in that regard.
Kilauea is a young stage 4 volcano.
Both. Kilauea erupts in both explosive and effusive phases and is generally considered to be in the sheild-building phase of Hawaiian volcanism.
The last eruption of Kilauea began on December 20th, 2020 and ended May 23rd of 2021. The volcano is now considered dormant since there is no longer any active lava on the surface.
Kilauea is about 45 miles southwest of Hilo, in Hawai’i Volcanoes National Park. The park was actually one of the very first established in the United States.
Kilauea’s near-constant eruptions results in a lot of sulfur dioxide gas being poured into the atmosphere. The result of this is volcanic air pollution downwind of Kilauea. This sulfur dioxide is hard on the environment around the volcano and can not only cause health issues in people, but can eventually lead to the death of livestock.
In Hawaiian mythology, Kilauea is said to be the home of a family of fire gods. One of the sisters, Pele, is the Hawaiian goddess of fire and volcanoes. She is said to mind Kilauea and be responsible for controlling the volcano’s lava flows. There are many traditional legends that involve Pele and Kilauea.
