Why Is Kīlauea Considered One of the Most Active Volcanoes?
Kīlauea is considered one of the most active volcanoes in the world due to its frequent eruptions and continuous lava flow. As a shield volcano, it consistently produces low-viscosity lava, which enables it to erupt frequently, often over extended periods.
According to the United States Geological Survey (USGS), Kīlauea has erupted more than 30 times since 1952. This frequent activity categorizes it among the most active volcanoes globally.
The underlying causes of Kīlauea’s activity stem from its geological setting. Kīlauea sits on the Hawaiian hotspot, a stationary plume of molten rock rising from deep within the Earth. The hotspot supplies magma that feeds the eruptions. As tectonic plates move over this hotspot, magma accumulates, creating pressure that eventually results in volcanic eruptions.
Several technical terms help explain this process. Magma is the molten rock beneath the Earth’s surface. When it erupts onto the surface, it is called lava. Tectonic plates are large pieces of the Earth’s crust that float on the semi-fluid mantle below. Their movement can produce volcanic activity.
The specific conditions that contribute to Kīlauea’s eruptions include its location and composition. The magma at Kīlauea is relatively low in viscosity, allowing it to flow easily. This characteristic leads to frequent eruptions that produce extensive lava flows rather than explosive blasts. Additionally, the presence of underground storage chambers allows for the buildup of pressure, which culminates in eruptions.
For example, the 2018 eruption of Kīlauea led to the opening of numerous fissures, resulting in dramatic lava flows that destroyed homes and reshaped the landscape. These scenarios illustrate how Kīlauea’s unique attributes contribute to its status as one of the most active volcanoes in the world.
