Whakaari/White Island Shows Signs of Eruption, Aviation Alert Raised to Orange Level

In a concerning development, Whakaari/White Island is showing signs that it may be entering a new eruptive episode, prompting authorities to raise the aviation colour code to orange, while the volcanic alert level remains at 2. The elevation to orange indicates heightened unrest, suggesting an increased likelihood of an eruption or that an eruption is already underway, albeit with little to no ash emission at this stage. The situation unfolded during a routine gas measurement flight on December 14, when scientists noted a change in emissions from the active vent of the volcano. The findings revealed an increase in volcanic ash compared to the emissions recorded just an hour earlier. This dramatic shift, along with satellite observations, indicated a rise in sulphur dioxide (SO2) and carbon dioxide (CO2) emissions, which are often precursors to volcanic activity. Mazot, a representative from GNS Science, stated, "The results from the gas flight along with satellite observations show a general increase in sulphur-dioxide and carbon dioxide emissions from the volcano." This increase, together with the minor volcanic ash emissions observed, raises concerns that a new eruptive episode may be on the horizon. Further illustrating the volcano's heightened activity, on December 10, a large steam and gas plume was recorded above Whakaari, captured by GNS webcams in Whakatāne and Te Kaha, as well as in satellite imagery. Mazot explained that, depending on the weather, the plume might be visible from the Bay of Plenty coast, demonstrating the volcano's potential impact beyond its immediate vicinity. While there have been reports of minor ash emissions, Mazot emphasized that these have yet to be visually confirmed through webcam monitoring or satellite analyses from Metservice. In the absence of sensors directly on the island, scientists are relying heavily on remote monitoring techniques to assess ongoing activity. The observations made from May to September indicated that the changes in activity might be driven by the presence of fresh magma. Although recent emissions have been minor, the volcanic landscape remains unpredictable. Mazot warned that the volcano could escalate to more dangerous levels of activity with little to no warning. The GNS Science volcano monitoring group, alongside the national geohazards monitoring centre, will continue to closely observe Whakaari/White Island for any signs of increased activity. "We will provide further updates when information becomes available," Mazot assured. As the situation develops, GNS has advised the public to stay informed about the potential impact of the steam and gas plume, especially if it reaches the coast. Safety protocols and advice should be closely followed as the region navigates this uncertain and potentially hazardous phase in the life of Whakaari/White Island.
