Perched lava lake surrounded by a levee. NPS Photo/J.Wei. Lava Levee. Levees develop on the chilled margins of a lava lake and may be higher than the surface of the lava depending on the flow rate and pressure within the shallow magma reservoir of Kīlauea. As in this picture, small overflows of lava over a levee can occur.

Continuous lava lake activity began in February 2010. The lake rose significantly in late 2010 and early 2011, before subsequently draining briefly in March 2011. This disruption of the summit eruption was triggered by eruptive activity on the East Rift Zone.
Volcano Watch — Kīlauea’s ongoing eruption: a rising lava lake
2020年12月31日 · As last week’s “Volcano Watch” went to press, lava continued to erupt from two vents on the west and north sides of Halemaʻumaʻu crater at a combined rate of approximately 30 cubic m (1060 cubic ft) per second. The rise of the lava lake was slowing due to the funnel-like shape of Halemaʻumaʻu.
