Seismic array deployed to better understand magma transport during Kīlauea'
University of Utah seismologists install a nodal geophone on Kīlauea's lower East Rift Zone in June 2018. This instrument was part of a network of 82 seismometers deployed temporarily this summer to help scientists study the magma transport system beneath the volcano's eruption sites. USGS photo by B. Shiro.

GeoGirls Examing Tephra Deposits
The GeoGirls examined tephra (ash and pumice) deposits from Mount St. Helens’ eruptive past and learned how to create a stratigraphic column.

Kīlauea lower East Rift Zone
From September 4-7, the Unmanned Aircraft Systems flew several missions documenting changes within the fissure 8 cinder cone. On September 4, lava erupted from an opening on the surface of the flow, to build a small cone. Lava flowed onto the floor but did not flow outside the walls of the cone.

Kīlauea summit
The Unmanned Aircraft Systems (UAS) team completed its mission at Kīlauea Volcano's summit, mapping changes within the caldera. Since August 4, 2018, the number of earthquakes at the summit have decreased and the rate of subsidence has stabilized.

GPS monitoring station P709
GPS monitoring station P709 is located on The Promontory between the South Arm and Southeast Arm of Yellowstone Lake. It was installed in 2005 as part of the Yellowstone component of the National Science Foundation's Plate Boundary Observatory (PBO) under permit YELL-SCI-5546.

Kīlauea lower East Rift Zone
An Unmanned Aircraft Systems overflight yesterday (September 4, 2018) showed a small cone on the floor of the crater within fissure 8. The cone formed as lava erupted from an opening in the surface of the flow that covers the crater floor.

A closer view of the small cone forming on the floor of crater within fissure 8
A closer view of the small cone forming on the floor of crater within fissure 8 today (Sept. 5). By this morning, bits of molten lava emitted from the cone every few seconds had built it up to an estimated height of around 3-4 m (about 10-13 ft).
