Kilauea Eruption: February 12 Update

Volcano Watch Remains High as Kilauea Continues its Spectacular Show

The Kilauea volcano on Hawai'i Island continues its eruptive activity, captivating scientists and onlookers alike. This update provides a summary of the situation as of February 12th, drawing from the latest observations and reports from the United States Geological Survey (USGS) Hawaiian Volcano Observatory (HVO). While the eruption remains relatively stable, it's crucial to remember that volcanic activity is inherently unpredictable.

Current Eruptive Activity at Halemaʻumaʻu Crater

The current eruption, confined to Halemaʻumaʻu crater within Kilauea's summit caldera, shows no signs of significant changes in intensity. Lava continues to fountain and fill the crater floor, creating a mesmerizing spectacle of glowing lava lakes and spatter cones. The USGS HVO continues to closely monitor lava effusion rates, gas emissions, and ground deformation to detect any potential shifts in activity.

Lava Lake Levels and Observations

Lava lake levels have fluctuated in recent days but remain generally high. Observers have reported robust lava fountaining, with occasional surges and pulses adding to the dynamic nature of the eruption. The exact dimensions of the lava lake are constantly evolving, making precise measurements challenging. However, HVO scientists diligently collect data using a variety of methods, including thermal imaging and visual observations.

Gas Emissions and Air Quality

Significant amounts of volcanic gas, including sulfur dioxide (SO2), continue to be released. These gases can create vog (volcanic smog) that can impact air quality downwind. Residents and visitors in affected areas should be aware of potential health hazards and check air quality reports regularly. HVO provides regular updates on gas emissions and their potential impact.

Seismic Activity and Ground Deformation

Seismic activity around the summit remains relatively low, indicating that the current eruptive activity is well-contained within Halemaʻumaʻu crater. However, minor earthquakes are still being recorded, which are typical during periods of volcanic unrest. Ground deformation measurements continue to provide valuable insights into the movement of magma beneath the surface and aid in predicting potential changes in eruption style.

Hazard Zones and Safety Precautions

It is crucial to remember that the area around Kilauea volcano remains hazardous. The active lava lake and associated gas emissions pose significant risks. Visitors should strictly adhere to safety guidelines and only observe the eruption from designated viewing areas. Never enter restricted zones or approach the active lava flows. Always stay informed by monitoring official updates from the USGS HVO.

Kilauea Eruption: Long-Term Implications

While the current eruption is spectacular, it is important to view it within the broader context of Kilauea's volcanic history. Kilauea is one of the world's most active volcanoes, and its eruptive activity can vary dramatically over time. This current event, while impressive, is just one chapter in its long and complex geological narrative.

Monitoring and Future Predictions

The USGS HVO's continuous monitoring is vital for understanding the volcano's behavior and for issuing timely warnings to protect public safety. Predicting the future course of the eruption remains challenging, however, constant observation and data analysis provide the best possible insights into potential changes. HVO scientists work tirelessly to provide accurate and up-to-date information to the public.
