Unoccupied Aircraft System is inspected by pilot just before take off

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.

Timelapse video of the water pond at Kīlauea summit

This timelapse video covers 1.5 hours and shows the motion of the water surface at the summit of Kīlauea. Along the shoreline, areas of apparent water influx are visible, often with a slightly greener color. Shifting steam on the surface attests to the high temperature of the water and the winds at the bottom of the crater. The contrast has been enhanced to highlight the

Water appears in Halemaʻumaʻu - Kīlauea Volcano

USGS Hawaiian Volcano Observatory scientists Matt Patrick and Jim Kauahikaua talk about the water that appeared at the bottom of Halemaʻumaʻu, a crater at the summit of Kīlauea Volcano, in July 2019 and continues to rise today. They address why it appeared, how it’s monitored, and its potential hazards.

Timelapse view of the Kīlauea summit water pond

This timelapse video covers about 30 minutes of activity at the water pond in Halema‘uma‘u at the summit of Kīlauea. Water appears to be flowing into the pond from several locations, including the southern boundary (right side in this image). A small amount of material is also seen floating on the surface at the eastern end of the pond (top of image). The video is shown

Video of circulation in the Halema‘uma‘u water pond

This time-lapse video shows circulation in the water pond in Halema‘uma‘u over a period of about 25 minutes. There appears to be an influx of water along the southern (right) shoreline. A broader eastward flow of water (toward top of image) is evident. The video is shown twice. USGS video.

Two views of the Halema‘uma‘u water pond

Views of the water pond in Halema‘uma‘u on Friday, September 6, and Monday, September 9 are shown in this video. Ripples are evident on the pond, presumably due to wind moving over the water surface. No significant changes in the pond were observed over the weekend, and the water level continues to slowly rise. USGS video by M. Patrick.

Changing activity on the surface of the Halema‘uma‘u water pond

Shown at 30x speed, this video highlights changing activity on the surface of the water pond. Steam wafting above the pond shifts in the wind, and circulation of the water is evident in areas of sharp color boundaries. USGS video by M. Patrick, 09-17-2019.

830-year-old explosion deposit
April 12, 2018

Three deposits from explosive eruptions at the summit of Mauna Loa are located west, northwest, and east of Moku‘āweoweo, the volcano's summit caldera. In map view, these deposits are fan-shaped. Along the ‘Āinapō Trail, 2.8 to 3.5 km (1.7 to 2.2 mi) southeast of the caldera, several kīpuka expose a fourth distinct explosive deposit.

Degraded coral reefs at Kahekili Beach Park, west Maui, Hawai‘i.
March 30, 2018

According to a study by USGS scientists, polluted, low-pH groundwater discharging onto a shallow coral reef off Kahekili Beach Park in west Maui, Hawai‘i, further increases seawater acidity and exposes corals to nitrate concentrations 50 times higher than normal.
