USGS Hawaiian Volcano Observatory scientists examine an outcrop of reddish-brown Hilo ash during a recent study to investigate the origins of volcanic ash deposits on the Island of Hawai‘i. Age dates of lava flows above and below the Hilo ash deposit indicate that the ash was erupted between 3,000 and 14,000 years ago.

On December 30, 2015, an HVO geologist wore protective gear during collection of a fresh lava sample for chemical analysis from a Pāhoehoe breakout along scattered Pu‘u ‘Ō‘ō lava flows. Inset image caption: Metadata is written on a bag that holds a sample taken from Pāhoehoe that was collected on August 18, 2006.

Stormy weather moved through the islands over the past day, producing snow at the higher elevations of Mauna Kea and Mauna Loa. This sequence shows the webcam images at the summit of Mauna Loa, and the variable weather throughout the day.

The sampling mechanism (on blue tarp) is prepared and the Unoccupied Aircraft System (UAS) is inspected just before take off to collect water from the Halema‘uma‘u crater lake. Brightly colored flagging tape tied to a cable attached to the UAS indicated depth as the sampling tool was lowered into the water. 

Geophysicist Brian Shiro, manager of the USGS Hawaiian Volcano Observatory's seismic network, was part of HVO's team that installed several new stations on Kīlauea Volcano's lower East Rift Zone to monitor earthquakes during the 2018 eruption.
