UPDATE: The ongoing eruption at Kilauea, which began on December 23, 2024, is showing signs of a potential new episode, with forecasts indicating that Episode 39 could erupt between December 22 and 27, 2025. This dynamic activity has captivated visitors at Hawaii Volcanoes National Park for nearly a year, showcasing stunning lava fountaining that has not been observed for nearly 40 years.
The eruption has produced intense lava fountaining, with molten lava reaching heights of 460 meters (1,500 feet). This phenomenon has dramatically reshaped the landscape surrounding Halema‘uma‘u, leading to the formation of a new 42-meter (140 ft) tall pu’u and a significant rise in the caldera floor by 223 feet (68 meters). However, this beauty comes with inherent dangers, making safety a priority for park officials and visitors alike.
Recent reports from the USGS Hawaiian Volcano Observatory (HVO) detail the urgency of the situation. The latest episode, Episode 38, occurred on December 6, 2025, and lasted for 12 hours, showcasing powerful inclined fountaining that reached over 300 meters (1,000 feet). This rapid escalation of hazards serves as a reminder of the unpredictable nature of volcanic activity.
As the eruption continues, HVO officials emphasize that life-threatening hazards exist within the closed areas of the park. The risk of hot tephra falling extends beyond the immediate vicinity of the vents, especially when winds shift. During previous episodes, tephra has been documented falling on Uekahuna Bluff, just a mile away, highlighting the importance of adhering to park guidelines.
The HVO team is actively monitoring Kilauea’s activity, utilizing advanced technology to track ground deformation and seismic activity. Engineers are navigating thick tephra deposits to maintain monitoring stations, while geologists collect vital data to understand the eruption’s evolution. This concerted effort ensures that the public receives timely updates and safety information.
As of December 15, 2025, the eruption is temporarily paused, with intermittent glow visible at the south vent. The summit is currently reinflating, indicating that another fountaining episode may be imminent. Visitors to the park are urged to stay informed about ongoing developments and to respect the closed areas for their safety.
This unprecedented eruption is a once-in-a-lifetime opportunity for many to witness the power and beauty of Hawaiian volcanoes. As the situation develops, staying informed through official channels is crucial. For the latest updates, please visit the HVO website and follow their guidance.
In the coming days, as the window for Episode 39 approaches, the eyes of the world will be on Kilauea. Be prepared and stay safe!
