This photo shows one of the islands near the inlet in the lava lake in Halema‘uma‘u, at the summit of Kīlauea. Over the past two weeks, the island has tilted 90 degrees, producing the vertical layering visible here. USGS photo by M. Patrick on March 22, 2021.

This photo shows the levee that bounds the southern margin of the active lake in Halema‘uma‘u. The levee is formed, in part, by numerous small crustal plates pushed over the rim. USGS photo by M. Patrick on March 22, 2021.

On Thursday, March 18, lava continued to erupt from the west vent in Halema‘uma‘u crater at Kīlauea Volcano's summit. Two lava inlets near the base of the west vent (center) supply lava into the lava lake. This photo was taken around 7:15 a.m.

On March 18, 2021, morning light illuminated the west vent in Halema‘uma‘u crater at Kīlauea Volcano's summit. Small collapses of the cone have accumulated into a loose pile of rubble (left) on the stagnant crust at its base—adjacent to the active lava lake (lower-right). USGS photo by K. Lynn.

USGS hydrologist Adam Birken cleans and inspects the water height reference staff at the USGS streamgage site on the South Fork of the Ogden River near Hunstville, Utah. This streamgage has been monitoring water levels and flow since March 21, 1921, making it one of 25 centennial gauges in Utah.

Outline of the Steamboat and Cistern plumbing systems, with two viewing angles. The structure, color-coded by depth, delineates the observed seismically active area during eruption cycles of Steamboat Geyser. The solid star, solid square, and open triangles denote Steamboat Geyser, Cistern Spring, and seismic station locations on the surface, respectively.
