HONOLULU – Kilauea, one of the world’s most active volcanoes, continues to captivate and occasionally disrupt life on Hawaii’s Big Island. The volcano’s latest eruptive episode, marked by spectacular lava fountains reaching heights of 1,000 feet, prompted temporary closures at Hawaii Volcanoes National Park and along a key highway on Tuesday, March 10, 2026. The ongoing activity, which began in December 2024, highlights the dynamic geological forces shaping the Hawaiian Islands and the challenges of coexisting with an active volcano.
The fountaining, the 43rd episode since the eruption began, commenced Tuesday morning and was visible via a livestream provided by the United States Geological Survey (USGS). The USGS stream showed two distinct fountains of bright-red lava and plumes of smoke rising from Kilauea’s summit. Whereas the duration of these fountaining events varies – some lasting only hours, others stretching over several days – the current episode has already caused logistical challenges for both residents and visitors. The eruptions at Kilauea are a constant reminder of the power of nature and the need for preparedness in volcanic regions.
Volcanic Activity Prompts Park and Highway Closures
The primary concern stemming from the latest eruption isn’t lava flow directly threatening infrastructure, but rather the dispersal of volcanic tephra – glassy volcanic fragments and ash – downwind. This tephrafall led to temporary closures within Hawaii Volcanoes National Park, specifically in areas surrounding the summit, and a partial closure of Highway 11, a crucial transportation route around the island. The closures were implemented as a safety precaution to protect travelers and park visitors from the potential hazards of falling debris. Highway 11 remains a vital artery for commerce and tourism on the Big Island, and even partial closures can significantly impact travel plans.
Hawaii County officials proactively opened a shelter at a district gymnasium to accommodate residents and tourists affected by the road closures or the falling tephra. According to Tom Callis, a county spokesperson, the shelter was opened as a precautionary measure, though it initially saw limited utilize. The availability of such shelters demonstrates the county’s commitment to ensuring the safety and well-being of its population during volcanic events. The potential for tephra to disrupt daily life extends beyond immediate safety concerns, as it can likewise impact water catchment systems, a common source of freshwater on the Big Island.
Understanding Volcanic Tephra and its Impacts
Volcanic tephra, composed of fragmented volcanic material ejected during an eruption, poses several risks. County officials have warned that tephra can cause irritation to the eyes, skin, and respiratory system. More significantly, it can clog and damage water catchment systems, which are relied upon by many residents for their water supply. Past episodes of heavy tephrafall have necessitated assistance from Hawaii County civil defense workers to help communities clear ash accumulation from homes and infrastructure. The potential for widespread disruption underscores the importance of ongoing monitoring and public awareness campaigns.
The National Weather Service issued an ashfall warning in response to the eruption, advising residents to accept precautions to minimize exposure to the airborne particles. This warning highlights the broader regional impact of Kilauea’s activity, extending beyond the immediate vicinity of the volcano. The USGS continues to monitor the eruption closely, providing updates and assessments of the ongoing hazards. Understanding the composition and behavior of tephra is crucial for mitigating its effects and protecting public health.
Kilauea’s Eruptive History and Current Status
Kilauea is renowned as one of the world’s most active volcanoes, with a history of frequent eruptions. The current eruptive phase, which began in December 2024, has been characterized by intermittent fountaining and lava flows confined within the summit crater of Hawaii Volcanoes National Park. While previous eruptions have posed a direct threat to communities, the current activity is largely contained within the park boundaries, minimizing the risk to populated areas. However, the potential for changes in eruptive behavior remains a constant concern.
In November 2025, a previous eruption dispensed nearly 11 million cubic yards of lava – a volume sufficient to fill an Olympic-sized swimming pool every 5.5 seconds, according to the USGS. This demonstrates the sheer scale of volcanic activity at Kilauea and the immense power contained within the Earth. The ongoing monitoring efforts by the USGS and Hawaii County officials are essential for tracking the volcano’s behavior and providing timely warnings to the public. The livestream of the eruption provides a valuable tool for scientists and the public alike to observe the dynamic processes unfolding at Kilauea.
Impact on Air Travel
The volcanic ash plume also impacted air travel. Hawaiian Airlines announced the cancellation of five round-trip flights between Honolulu and Hilo on March 11, 2026, and diverted two flights to Kona due to the ash. This disruption highlights the broader economic consequences of volcanic activity, extending beyond local communities to affect regional transportation networks. The airline’s swift response underscores the importance of prioritizing safety in the face of volcanic hazards. Travelers planning to visit the Big Island are advised to check with their airlines for the latest flight information.
Looking Ahead: Continued Monitoring and Preparedness
The situation at Kilauea remains fluid, and the duration of the current fountaining episode is uncertain. The USGS continues to closely monitor the volcano’s activity, analyzing data from a network of sensors and providing regular updates to the public. Hawaii County officials are prepared to respond to any changes in the eruption’s behavior, including potential shifts in the direction of tephrafall or the emergence of new hazards. The ongoing collaboration between scientists and emergency management personnel is crucial for ensuring the safety of residents and visitors.

The Kilauea eruption serves as a powerful reminder of the dynamic forces shaping our planet and the importance of respecting the power of nature. As the volcano continues to erupt, ongoing monitoring, preparedness, and public awareness will be essential for mitigating the risks and ensuring the safety of communities on the Big Island. The next official update from the USGS is expected on March 12, 2026, providing further insights into the eruption’s evolution.
