Kilauea, Hawaii, USA

Based on observations during overflights, and web camera views when weather permitted, HVO reported that during 27 February-4 March activity from Kilauea’s fissure segment D was concentrated at the Thanksgiving Eve Breakout (TEB) shield and satellitic shields to the E and SE. A pahoehoe flow ponded between the rootless shields and Kalalua Cone. Two lava flow lobes advanced through Royal Gardens subdivision and destroyed three abandoned homes by 28 February. One lobe reached the base of the Royal Gardens kipuka and Campout flow from early 2007.On 1 March the lobes merged and cut off the road access to the homes of the last two known residents. Incandescence from the TEB vent was noted during 29 February and 2-3 March.Diffuse incandescence was observed in Pu’u ‘O’o crater through the fume during 27 February and 1-3 March. Earthquakes were located beneath Halema’uma’u crater, along the S-flank faults, beneath the summit, N of Makaopuhi crater, and along the upper E and SW rift zones. Sulfur dioxide emission rates from the summit area were elevated at 2-4 times background values where levels have been since early January. The emission rate was about 970 tonnes per day on 3 March, compared to a background rate of 150-200 tons per day.
