Mt Ruapehu’s crater lake – Te Wai ā-moe – sometimes goes via heating cycles, and GNS measurements present that early this month the temperature began constructing.
The mountain is presently at volcanic alert stage 1 – the bottom of 5 alert ranges.
GNS volcanologist Agnes Mazot mentioned what’s taking place on the mountain is typical for this time of 12 months.
“Stage 1 means its minor volcanic unrest it is the everyday stage for Mt Ruapehu in the intervening time and we’re anticipated to have a standard enhance of lake temperature within the close to future,” she mentioned.
Routine monitoring of the crater lake at Mt Ruapehu has been ongoing for the final 10 years together with common fuel measurements and crater lake water samplings.
“Now we have recorded cycles with lows of 15 levels and highs of 45 levels, it is annual, that is typical behaviour throughout the cycle.”
Mazot mentioned the crater lake Te Wai Wai ā-moe is initially of a heating cycle and that often coincides with a rise in fuel emission.
She mentioned there’s presently low threat of the lake stage rising.
“We additionally measure the lake stage similtaneously the lake temperature and we’ve an outlet so there isn’t a threat of the lake going greater than the extent till it switches water outlfow and goes to the Whangaehu River.”
