Kilauea (United States) - Report for 12 September-18 September 2018

HVO reported minor incandescence from a collapse pit in the central part of Kilauea?s Fissure 8 cone during 12-15 September, and that small amounts of fuming rose from a small spatter cone located towards the back of the Fissure 8 cone during 12-18 September.
Seismicity and ground deformation remain low at the summit, and aftershocks from the M 6.9 earthquake in early May were located along faults on the south flank.
The combined rate of sulfur dioxide emission from the summit and the LERZ (less than 1,000 tonnes/day) were lower than any time since late 2007.
Small collapses at Pu'u 'O'o Crater during 12-14 September generated visible dust plumes.
The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange.
