Rising summit lava lake levels peaked overnight, producing small overflows onto the floor of Halema‘uma‘u Crater. This photo shows the largest overflow, on the north margin, which reached about 80 m (262 feet) from the lake margin.

A wider view of the lava lake and recent overflows. This photo is taken from the Halema‘uma‘u Crater rim, and looks northwest. Jaggar Museum and HVO can be seen on the skyline.

There were much smaller overflows on the west margin of the Overlook crater rim.

A line of spattering along the northwest lake margin. Note that the spatter is being ejected well above the level of the Halema‘uma‘u Crater floor, with occasional small bits landing on the rim. At the left end of the spattering, a piece of the thin, flexible crust on the lava lake is lifted and torn by a bubble burst.

This video shows an overview of the lake from the Halema‘uma‘u Crater rim, as well as some of the spattering that was occurring on the lake margin.
