To survey the bathymetry off of the Pea Island DUNEX site WHOI investigator Peter Traykovski prepares to run into the surf with the ASV nicknamed "Robo Turtle" while USGS investigator Chris Sherwood handles the remote controller.

The Helikite in action, being walked by WHOI scientist, Peter Traykovski, at Pea Island DUNEX site, the helium powered balloon kite is used to survey the beach and dune to produce elevation models using Structure from Motion.

No changes were observed at Kīlauea's summit during a brief field visit on September 3, 2021. Sunny weather made for spectacular views, though strong winds were blowing. The solidified crust of the lava lake within Halema‘uma‘u—which was active from December 2020 to May 2021—is visible in the lower center of this image. USGS photo by K. Mulliken.

View from a temporary webcam, which is located just southwest of Kīlauea summit caldera, and looks south over the area of the August 2021 intrusion. The dark lava flow on the left of image (mid-ground) is where the 1982 lava flow spilled out of the south caldera.

To survey the bathymetry off of the Pea Island DUNEX site WHOI investigator Peter Traykovski, and USGS investigator, Chris Sherwood, prepare to launch the ASV into the water to measure the bathymetry of the Pea Island DUNEX site.

Station HRPKE is located southwest of Kīlauea's summit, in the upper Southwest Rift Zone region, within Hawai‘i Volcanoes National Park. The station measures sulfur dioxide (SO₂) concentrations in the air, as well as local meteorological data such as wind speed, wind direction, and rainfall.

HVO technician Steven Fuke checks the solar panel at station HRPKE while conducting station maintenance on September 1. HVO remote monitoring stations are powered via solar panels and a suite of batteries.

On August 31, the water level in Keller Well was measured at approximately 514.12 m (1686.75 ft) below the ground surface. Though an intrusion of magma took place beneath the ground surface in Kīlauea's south caldera region from August 23–30, water level in Keller Well does not show significant changes as a result of this event.

On Tuesday, August 31, Hawaiian Volcano Observatory (HVO) scientists and technicians visited the Keller Well in Kīlauea's south caldera region. Water from the well is typically sampled and analyzed quarterly to monitor how magma supply to Kīlauea's summit reservoirs might impact regional ground water.

This map depicts the detected intrusive activity over the past week at Kīlauea Volcano. The initial swarm of small earthquakes from August 23–25 was centered in the south caldera region, as labelled on the map.
