Two NZ Volcanoes Show Signs of Unrest

Mt Ruapehu

A volcanic earthquake swarm has been reported at Mt Ruapehu. The seismicity began on April 26. The Crater Lake temperature, which has been rising since October 2015,  has now reached 40°C (from 25°C in mid-April). Mt Ruapehu remains at Volcanic Alert Level 1 (Minor volcanic unrest), Geonet reported.

White Island

A minor eruption occurred at White Island (Whaakari) at about 11:00 pm on Wednesday, 27 April 2016. Moderately elevated seismic activity is occurring, said Geonet. Additionally:

  • Water level in the Crater Lake has fallen by 2m in the last 2 weeks.
  • Lake temperature has increased by 2°C, to 58°C, since February.
  • SO2 output ranging from 90 to 480 tons per day reported over the last 5 weeks, but said to be typical values for White Island.

“A dark-green ash deposit from the eruption covers at least 80% of the floor of Main Crater, and up the sides of the crater wall on both the north and south sides. At a distance of 500 m from the eruption site the ash deposit is about 5 mm thick. The green colour is due to minerals on the ash.”

Alert Level was initially raised to Level 3 (Minor Volcanic Eruption) and the Aviation Color Code to Orange. The Alert Level was lowered to 2 from 3 on Thursday.
