Deploying two seismic sources
Jenny McKee and Peter Dal Farro of the USGS Pacific Coastal and Marine Science Center swing a pair of seismic sources, also called air guns, and the gun hanger, out over the water to deploy them during the 2018 MATRIX cruise. Scripps Institution of Oceanography's seismic streamer is coiled on the blue winch in the foreground.

Kīlauea summit
Kīlauea Volcano’s summit, seen here from the northeast rim of the caldera, has remained quiet, with no collapse events since August 2. It remains too soon to tell if this diminished activity represents a temporary lull or the end of summit collapses.

View Into Fissure 8 Cinder Cone
The Unmanned Aircraft Systems (UAS) team assessed conditions at the fissure 8 cone and upper lava channel on August 17, 2018. At the time of the flight, the lava pond within the cone had crusted over with no observed incandescence.

3D Model of Fissure 8 Cone
This 3-dimensional computer model shows the structure of the fissure 8 cone on Kīlauea Volcano's lower East Rift Zone. The model was created from thermal images acquired during a helicopter overflight on August 15, 2018. The cone is currently about 30 m (100 ft) tall with a broad base.
