The advancing lava flow continues to enlarge the lava delta on the western part of the island by emerging from the main conduit.

On 17 October, the Aviation Color Code was decreased to Green and the Alert Level for the volcano to Yellow, although mariners continue to be advised to avoid an area of 4 km distance from the island until further notice.

The Tonga Geological Services reported the current measurements of the island: 424 meters in a north-south linear area and 223 in an east-west line with a height of 15-18 meters above sea level.
