We undertook an observation and gas flight today to obtain updated information on the activity. The observations confirm minor geysering activity has continued within the crater lake. The lake level is lower than before this activity started, and has not fallen over the weekend, and the lake has progressively changed to a grey colour. The activity level today was lower than seen late last week. We have obtained gas data and will shortly be undertaking an analysis; we will report any significant changes.

As we have no sensors on the island we are currently relying on webcams, satellite imagery and other remote sensing to assess the situation. These remote techniques are complemented by our observation and gas flights. Based on our limited information there have been no clear indications of the current volcanic episode intensifying or declining. No volcanic ash plumes have been noted.

Volcanic activity witnessed over the weekend indicates that Whakaari may be entering into an eruptive episode. To date we have only seen short lived periods of energetic steam and gas emissions. No activity has been sustained.

There are no clear signs that the current level of minor eruptive activity is increasing, decreasing or stable. This could change with little to no warning. Should future eruptions become larger they may produce volcanic ash.

GNS Science volcanologists are monitoring the volcano and further information will be released as available. As that information becomes available, we may change the Volcanic Alert Level to more accurately reflect the current situation.
