This device, called a Raspberry Shake, is a sensitive instrument used to detect ground shaking. It is being carefully buried in this shallow hole in the tundra, to isolate it from wind.

Black streak on caldera wall (center) is about 50 m (yards) long, and white steam plume (lower right) rises from northwestern part of Halema‘uma‘u. Photo from Volcano House Hotel on July 4, 2018. The configuration of this area changed considerably after the photo was taken, as collapse continued into early August.

This animated GIF shows a sequence of radar amplitude images that were acquired by the Agenzia Spaziale Italiana CosmoSkyMed satellite system. The images illustrate changes to the caldera area of Kīlauea Volcano that occurred between May 5 and July 4 at about 6:00 a.m. HST.

Near the coast, the northern margin of the flow field is still oozing pasty lava at several points in the area of Kapoho Agricultural and Beach Lots.

The lava channel from fissure 8 jumped its banks near Kapoho Crater where the channel makes a 90 degree bend. The flow within the channel was diverted around a constricted area and joined the channel again "downstream" to the south (left).

Lava within the fissure 8 cone roils and churns where it eupts from the vent and flows rapidly down the well-established channel. This image was captured via a Mavic Pro drone courtesy of the DOI/USGS Unmanned Aircraft Systems team.

Evolution of a blocked channel, photo 1. A blockage of rafted material within the lava channel causes lava to flow over its banks near the Kapoho cone. In this section of the lava channel a cold lava flow from the 1960 eruption forms a barrier on the north side, which initially directed the channel to the southeast.

During the overnight hours, the UAS (Unoccupied Aircraft Systems) team flew sections of the lower East Rift Zone, monitoring fissure 8 activity and reports of small overflows from the lava channel.

Fissure 8 and the upper lava channel, viewed from the early morning helicopter overflight of the lower East Rift Zone. Recent heavy rains have soaked into the still-warm tephra and the moisture rises as steam (right side of lava channel).

Inward slumping of Halema‘uma‘u continues in response to ongoing subsidence at Kīlauea Volcano's summit. This image, taken from a temporary observation post located at Volcano House, shows steep walls on the western side of the crater and sloping piles of rubble from rockfall events.
