The Prelude to Eruption

Kīlauea's 2018 eruption was preceded by months of increased seismic activity. The U.S. Geological Survey (USGS) closely monitored the volcano, noting a rise in earthquake frequency and intensity.

Seismometers detected numerous small tremors in the East Rift Zone. These events signaled magma movement beneath the surface, as pressure built within Kīlauea's chambers.

Ground deformation instruments revealed subtle changes in the volcano's shape. GPS stations and tiltmeters measured slight swelling, indicating magma accumulation.

Scientists observed fluctuations in gas emissions from Kīlauea's summit. Increased sulfur dioxide levels suggested fresh magma rising closer to the surface.

While Kīlauea showed signs of unrest, nearby Mauna Loa remained relatively quiet. This allowed researchers to focus their attention on Kīlauea's evolving situation.

The USGS issued regular updates to local authorities and the public. These reports highlighted the potential for an eruption, though its exact timing and location remained uncertain.

As tensions grew, residents in high-risk areas prepared for possible evacuation. Emergency management officials reviewed response plans and conducted drills.

The final days before the eruption saw an intensification of earthquake swarms. These clusters of seismic events hinted at the impending volcanic activity that would soon reshape the landscape.

Anatomy of Kilauea

Kilauea's complex internal structure and dynamic magma system drive its frequent eruptions. The volcano's plumbing network and magma chambers play crucial roles in shaping its eruptive behavior.

Volcanic Structure and Plumbing System

Kilauea features a summit caldera atop a vast network of underground magma pathways. The caldera measures about 4 km wide and 3.2 km long, with steep walls dropping 120 meters to the crater floor. Beneath the surface, a complex plumbing system connects the summit to the East Rift Zone.

This rift zone extends 125 km from the summit to the ocean floor. It contains a series of fissures and vents, including the famous Puʻu ʻŌʻō crater. Magma moves through this system, causing ground deformation and eruptions along the rift.

Magma Chamber Complexities

Kilauea's magma storage system consists of multiple interconnected chambers. The primary summit reservoir lies 1-2 km below the caldera floor. It feeds smaller chambers along the rift zones through a network of dikes and sills.

Magma composition evolves as it moves through these chambers. Fresh, gas-rich magma from depth mixes with cooler, degassed magma in shallow reservoirs. This interaction affects eruption styles, ranging from effusive lava flows to explosive events.

Pressure changes in the magma chambers can trigger earthquakes and ground deformation. Scientists monitor these signals to forecast volcanic activity and potential hazards.

Eruption Chronology

The 2018 Kīlauea eruption unfolded in distinct phases, marked by intense geological activity and dramatic landscape changes. Fissures opened, lava lakes drained, and the summit experienced a massive collapse.

Initial Outbreak and Fissure Formation

On May 3, 2018, the first fissure erupted in Leilani Estates, signaling the start of Kīlauea's most destructive episode in modern times. Over the next weeks, multiple fissures opened along the Lower East Rift Zone.

Lava fountains reached heights of 300 feet, spewing molten rock and toxic gases. The fissures formed a chain of vents, feeding lava flows that consumed forests, roads, and homes.

By mid-May, Fissure 8 emerged as the dominant vent, producing a massive lava flow that reached the ocean.

Lava Lakes and Molten Pathways

As the Lower East Rift Zone eruption intensified, dramatic changes occurred at Kīlauea's summit. The lava lake at Halema'uma'u crater, active since 2008, began to drain rapidly.

The lake's surface dropped over 1,000 feet in just a few days. This drainage created a network of underground lava tubes, connecting the summit to the eruption site miles away.

These molten pathways allowed magma to flow freely from the summit reservoir to the active fissures, fueling the ongoing eruption in Leilani Estates.

Summit Collapse and Explosive Events

The continuous draining of magma from Kīlauea's summit led to a series of dramatic collapses. As the crater floor subsided, frequent earthquakes shook the volcano.

Explosive events at the summit sent ash plumes thousands of feet into the air. These explosions were triggered by rocks falling into the receding lava lake and interacting with groundwater.

The summit area experienced over 60 collapse events, significantly altering the volcano's topography. By August, the Halema'uma'u crater had more than doubled in width and deepened by over 1,600 feet.
