According to the United States Geological Survey (USGS), Kilauea is categorized as an active volcano that continually shows signs of eruptive activity. The USGS, a reputable organization, monitors and studies volcanoes to provide reliable information about their activity and potential hazards.
The primary underlying causes of Kilauea’s activity stem from its geological setting and magma dynamics. Kilauea is located on the Big Island of Hawaii, situated over a hotspot in the Earth’s mantle. This hotspot generates molten rock, or magma, which rises to the surface. The movement and pressure of this magma lead to eruptions.
Key technical terms include:
– Hotspot: A location where molten rock ascends from deep within the Earth, creating volcanic activity.
– Magma: Molten rock beneath the Earth’s surface; when it erupts, it becomes lava on the surface.
Kilauea’s eruptions are influenced by several mechanisms. The accumulation of magma beneath the volcano creates pressure. When this pressure exceeds the strength of surrounding rock, it results in an explosive eruption or a gentle lava flow. The summit caldera and the rift zones also play essential roles in how eruptions develop.
Specific actions contributing to Kilauea’s activity include tectonic movements and the influx of new magma. The Hawaiian Emperor seamount chain indicates plate movement. This movement creates fractures in the Earth’s crust, allowing magma to travel towards the surface.
