USGS scientist Cordell Johnson points to the Raspberry Shake, a sensitive instrument used to detect ground shaking. Johnson mounted the Raspberry Shake to an aluminum pole which he will then drive into the ground to bury the instrument beneath the tundra. This process will help isolate it from the wind.

At 1:20 PM HST on July 5, a collapse explosion event occurred at Kīlauea's summit. The energy released by the event was equivalent to a M5.2 earthquake.

Rocks generate brown dust as they tumble down the western caldera wall during the collapse explosion event on July 5, 2018.

Lava enters the sea along the Kapoho coastline, building a delta that is now over 555 acres in size.

Lava, from small overflows, cools and congeals along the banks of the lava channel to build lava levees. The levees also build up as moving lava pushes cooled crust over the edge.

Near the Kapoho Crater, in the area called Four Corners, the lava channel makes a 90-degree bend. After lava exits the bend, it makes a short drop to form a lavafall. A side channel makes a short surface diversion before rejoining the existing channel.

Having crusted over about 0.8 km (0.5 mi) upchannel from the ocean entry, lava oozes from the flow's molten interior to enter the sea along a broad flow front on the northern (Kapoho) side of the flow.

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.
