Kilauea Volcano Eruptions Provide Data on Lava Fountains
Key points
- Kilauea volcano experienced lava fountaining episodes.
- Underground lava reservoirs refilled rapidly since 2019.
- Researchers are analyzing data to understand fountaining mechanisms.
- Kilauea has 35 data-gathering stations for monitoring.
Lava Fountains Under Study
Hotspot-driven volcanism typically involves slow lava flows, but some locations like Hawaii exhibit dramatic lava fountains. The mechanisms powering these fountains, which can reach hundreds of meters, are not fully understood.
Recent eruptions at Kilauea volcano have provided extensive documentation, allowing US Geological Survey researchers to study these phenomena. Their findings are being compared with existing theories on lava fountain generation.
Kilauea's Recent Activity
Kilauea, Hawaii's youngest and most active volcano, has had three fountaining episodes since 1823. Its structure is well-understood due to intensive study, with identified lava residues near the surface.
The volcano is equipped with 35 data-gathering stations, including seismic, infrasound, geodetic, gas, and visual/thermal cameras, providing comprehensive monitoring.
Reservoir Refilling and Inflation
Following a major eruption in 2018 that partially drained an underground lava reservoir, indications showed steady refilling. This refilling accelerated starting in 2019, with the local peak inflating at over 22 cm per year.
By 2023, the inflation rate doubled to 57 cm per year and spread to a nearby caldera, indicating significant subsurface activity.
