The Tonga Geological Services reported that a new submarine eruption at Home Reef began at 0139 on 10 September based on a volcanic gas plume detected in satellite images. By 1259 material had formed a new small island, about 70 m in diameter and an estimated 10 m above the ocean surface. Gas emissions rose less than 1 km above the sea.
Submarine activity was detected during 12-13 September, and a thermal anomaly was identified in a satellite image acquired at 1400 on 13 September. The Aviation Color Code was raised to Yellow (the second lowest level on a four-color scale) and mariners were advised to stay 5 km away from the volcano. Gas emissions persisted at least through 14 September, with plumes rising less than 1 km.
