A closer view of a gravity reading at a station located in the south part of KÄ«lauea caldera. When repeated over time, gravity measurements can detect changes in subsurface mass that might not be detectable by other monitoring methods. Scientists track this data because the changes could be related to magma movement within the volcano. USGS photo by M. Poland, 03/20/2019.

Sediment runoff enters Pelekāne Bay following a wildfire and flash flooding in 2015. Overgrazing by feral ungulates and cattle are the most significant contributors to erosion, which can be exacerbated by heavy rainfall and wildfires. Photo courtesy Andrew Richard Hara.

Efforts underway to improve Pelekāne Bay water quality

The primary purpose of the project is to protect and improve the quality of water resources and reduce pollution flowing into Pelekāne Bay

This image is from a temporary monitoring camera on the west rim of Kilauea Caldera. The camera is looking East towards the bottom of the newly enlarged Halemaʻumaʻu crater, although the deepest part of the crater is not visible from this vantage point. The crater from left to right (roughly NNE to SSW) is approximately 1 km (0.6 mi) across. The depth of the crater in the visible image from the rim is several hundred meters.

This aerial view of the western part of Kīlauea Volcano’s caldera was taken on August 6, 2018. The down-dropped block is faulted about 120 m (400 feet) below the caldera floor. Many 19th-century lava flows are exposed in the fault scarps. Halema‘uma‘u (not visible) is to the left of this photo. USGS photo by D.Swanson.

Volcano Watch: New outcrops make good geology

As Halemaʻumaʻu sank and widened, its crater wall began to expose lava flows that formed during earlier eruptions and were covered by later flows.

Explosive eruption columns of ash rising from Halema‘uma‘u at 11:15 a.m. on May 18, 1924 (left) and at 11:05 a.m. on May 15, 2018 (right) look similar. Researchers are re-evaluating early assumptions about the role groundwater played in triggering these explosive eruptions at the summit of Kīlauea Volcano and are now looking at the build-up of gases from retreating magma as a likely trigger. USGS photos.

Volcano Watch: Did groundwater trigger explosive eruptions at KÄ«lauea?

An explosive eruption at Halema‘uma‘u in 1924 looks similar to the column of ash rising from Halema‘uma‘u in 2018.

After magma drained from Pu‘u ‘Ō‘ō on April 30, 2018, the crater was roughly 356 m (1168 ft) deep, with the upper part of the crater flared and the deeper part a narrower cylindrical shaft. Collapses on the crater walls have since enlarged sections of the crater and filled the deepest part with rockfall debris, creating a much different crater geometry—as shown in this comparison of models from May 11, 2018, and March 18, 2019. Today, the deepest portion of the crater is 286 m (938 ft).
