HVO reported that the summit eruption at Kilauea continued at a vent in the lower W wall of Halema`uma`u Crater.
By 16 November the total volume of erupted lava was an estimated 30 million cubic meters, and the lake which had risen a total of 60 m since 29 September.
During 17-23 November earthquake activity remained below background levels but volcanic tremor was elevated.
Spattering and ponded lava within the vent were visible; lava entered the lake through the E part of the W wall cone, feeding an active area of the lake.
Lava periodically oozed from the cooler, outer margins of the lake onto the lowest of the exposed down-dropped caldera floor blocks.
The sulfur dioxide emission rate remained above background levels, and was 3,000-3,800 tonnes per day on 18 and 23 November.
The Aviation Color Code and the Volcano Alert Level remained at Orange and Watch, respectively.
