The seismic recordings indicate a source beneath the summit area, which is normal for volcanic earthquakes and volcanic tremor at Ruapehu. The earthquake episode has ended.
The Crater Lake (Te Wai ā-moe) temperature has been around 24-25 ºC for the last few months. It is not unusual to observe volcanic earthquakes on Ruapehu and other episodes of increased seismic activity were observed during March 2018, April 2016 and September 2017. None of these resulted in a sustained increase in volcanic unrest.
Both the Volcanic Alert Level (level 1) and Aviation Code (Green) remain unchanged.
