New Zealand: Officials increase warning level at Mount Ruapehu volcano in Manawatu-Whanganui Region as of March 21

Event

Officials have raised the warning for Mount Ruapehu to Level 2 as of March 21 due to increased activity at the volcano. GeoNet has detected another heating phase at the volcano and crater lake together with high levels of volcanic earthquakes. The strong tremors may indicate an increase in gas flux through the system. The slow response of the lake temperatures suggests a partial blockage in the vent beneath the lake, which could result in pressure building up in the volcano and leading to a stronger eruption. Authorities warn that an eruption is increasingly likely.

As part of Level 2 measures, officials have created a 2-km (1.25-mile) radius exclusion zone around the center of the crater lake. An eruption could cause localized transport disruptions; flight delays are possible at Taupo Airport (TUO) if an eruption creates a significant ash plume. Ground transport disruptions could also occur. Authorities could suspend or delay rail service. Falling ash could cause slick driving conditions on nearby roads and reduced visibility, leading to localized traffic disruptions.

Advice

Heed the advice of local authorities and obey restrictions around the volcano. If larger eruptions occur, confirm flight schedules, especially at TUO. Drive cautiously, as roads may be slippery from volcanic ash. If operating in areas affected by an ash cloud, consider remaining indoors when possible. Individuals who must be outdoors should use face masks and observe other precautions to avoid ash inhalation. Volcanic ash and gases can cause eye irritation and respiratory problems. Do not rub irritated eyes; flush them with water. Seek medical attention if you have trouble breathing.
