The early morning helicopter overflight of the lower East Rift Zone shows lava continuing to enter the ocean at Ahalanui (view to the northeast). The southern margin of the flow remains about 500 m (0.3 mi) from the boat ramp at Isaac Hale Park this morning. The jetty along the launch ramp is visible near the center of the photo.

The fissure 8 channel continues to carry lava toward the coast on the west side of Kapoho Crater (vegetated cone, far left). Northwest of this cone, overflows (lower left) of the channel occurred overnight, but lava was confined to the existing flow field and did not threaten any homes or structures.

Hawaiian Volcano Observatory field geologists track activity at fissure 8 (pictured in the background). Crews collect fissure 8 tephra (airborne lava fragments, such as Pele's hair, pumice, and other lightweight volcanic glass fragments) for geochemical analyses and characterization of changes in lava fountain behavior.

As part of their ongoing monitoring work, HVO scientists measure temperatures at ground cracks along the fissure system in the Leilani Estates subdivision. On this day, temperatures ranged from from 100 to 145 degrees Celsius (200–300 degrees Fahrenheit), which is consistent with past readings.
