HVO reported that web camera views of fissure D from Kilauea’s 21 July fissure eruption were mostly blocked by fog and fumes during 5-9 December. A brief view on 5 December revealed several overflows on the W side of Pond 1, a perched lava pond in the eruption channel formed by fissure D. A pilot report from an overflight on 6 December noted that all of the activity was close to fissure D and none of the SE Thanksgiving Eve breakout (TEB) flows traveled beyond 1.5 km. On 8 December, minor incandescence was observed in Pu’u ‘O’o crater for the first time since 31 August, and was accompanied by a possible inflationary signal. Clear web camera views on 9 and 10 December revealed that the TEB shield continued to build vertically and was an estimated 15 m high. A few small earthquakes were located beneath the summit area and along the upper E rift zone and S-flank fault.
