Kilauea Volcano is one of the most active and well-known volcanoes in the world, located on the southeastern side of the Big Island of Hawaii in the United States. With its frequent lava flows and eruptions, Kilauea has been a significant geological feature and cultural icon in Hawaii for centuries. The volcano has been erupting almost continuously since 1983, making it one of the longest-lasting eruptions in recorded history. Kilauea’s history stretches back over 300,000 years, with the earliest eruptions creating the foundation for the Big Island of Hawaii. Today, Kilauea is a popular destination for visitors to Hawaii, who come to witness the power and beauty of one of the world’s most active volcanoes.

Geology and Formation of Kilauea Volcano
Kilauea Volcano is a shield volcano, meaning it has a broad, gentle slope that resembles a warrior’s shield lying on the ground. It is considered one of the most active volcanoes in the world, with frequent eruptions and lava flows.
Kilauea was formed through a process of volcanic activity that began over 300,000 years ago. It is located on the southeastern side of the Big Island of Hawaii, which sits on a hotspot in the Earth’s mantle. This hotspot is responsible for the creation of all the Hawaiian Islands and has been moving northwestward over millions of years.
The magma that feeds Kilauea is sourced from a chamber located deep beneath the surface of the Earth. When the pressure in the magma chamber builds up, it can cause an eruption. The magma flows out of the volcano’s vent and creates new land as it solidifies into lava rock. Over time, this process builds up the shield volcano.
Kilauea is known for its frequent lava flows, which can occur both from the summit caldera and from fissure vents on the volcano’s flanks. The lava that flows from Kilauea is typically low-viscosity, meaning it is thin and flows easily. This type of lava creates long, thin streams that can flow for miles and can also create lava tubes – hollow tunnels left behind after the surface lava has solidified.
Overall, the geology and formation of Kilauea Volcano is a complex and ongoing process, shaped by the movement of the Earth’s crust and the internal forces that drive volcanic activity.

- Safety Precautions: Visitors should be aware of the potential dangers associated with visiting an active volcano. These include toxic gas emissions, falling rocks, and lava flows. It is important to stay within designated viewing areas and follow all safety warnings and instructions from park rangers.
Overall, a visit to Kilauea Volcano can be a once-in-a-lifetime experience that offers a glimpse into the power and beauty of the natural world. However, visitors should be aware of the potential dangers and take appropriate precautions to ensure their safety.
Recent Eruptions of Kilauea Volcano
Kilauea Volcano has a long history of eruptions, with its most recent major eruption occurring from 1983 to 2018. During this time, the volcano produced a steady flow of lava that covered over 50 square miles of land and destroyed more than 700 homes. The eruption also created several new landmasses, including a new lava delta at the ocean entry point and a new island off the coast of the Big Island.
The 2018 eruption began in May of that year, when lava began to flow from several fissures on the volcano’s eastern flank. The lava flows destroyed dozens of homes and forced thousands of residents to evacuate their homes. The eruption also created a massive ash cloud that rose to over 30,000 feet, which disrupted air travel to and from the Big Island.
The eruption continued for several months, with lava flows changing direction and destroying new areas. By August 2018, the eruption had significantly decreased in intensity, and the majority of the active lava flows had ceased. The eruption officially ended in September 2018.
Since then, Kilauea has remained relatively quiet, with no major eruptions reported. However, the volcano remains active, and small eruptions and earthquakes continue to occur regularly. The United States Geological Survey monitors the volcano closely and provides updates on any changes in activity. Visitors to Kilauea should be aware of the potential dangers associated with visiting an active volcano and follow all safety guidelines and instructions from park rangers.
