Instead, the lake temperature has fluctuated between approximately 14 and 19 °C. While this represents some variation, it is relatively minor and falls within the range observed over the past 16 years. Recent data suggests that the inflow of hotter fluids has decreased over the last few months. Similar patterns were recorded in 2012–13, 2014, 2019, and 2022. ... [read more] ... [show less] Although the current inflow of hot fluid beneath the lake is relatively low, sulfur dioxide (SO₂) emissions remain at typical levels, indicating that the hydrothermal system is still open. Volcanic tremor activity continues to be weak. Taking all monitoring data into account, we assess the present activity as low-level and consistent with minor volcanic unrest. Accordingly, the Volcanic Alert Level remains at 1, and the Aviation Colour Code stays at Green.Kilauea (Hawai'i): The United States Geological Survey - Hawaiian Volcano Observatory (USGS-HVO) reported that there was a pause in eruptive activity at Kilauea between 23 February 2026 (local) and 24 February 2026 (local).
