Two new additions to the U.S. Geological Survey Great Lakes Science Center's fleet of large research vessels are currently being constructed. The two new USGS research vessels will replace the aging vessels on lakes Erie and Ontario.

Lava, erupting from the southwestern vent of the Kamoamoa eruption, fountains above the surrounding forest.

Overview of the Kamoamoa eruption looking northeast toward Pu'u 'O 'o, in the background. The southwestern vent is in the foreground, while the northeastern vent is the distant fume at the base of Pu'u 'O 'o.

View looking down onto the northeastern vent.

Lava fountains from the northeastern vent of the Kamoamoa eruption. Though it is an impressive sight, the Pu'u 'O 'o cone in the background, and several hundred meters higher, puts the current activity into perspective.

Overview of the Kamoamoa eruption looking south. The northeastern vent is to the left, and the southwestern vent is to the upper right. A river of lava, erupting from the southwestern vent, can be seen advancing toward the southeast through forest within Hawai'i Volcanoes National Park.

Views into the Halema'uma'u vent have been largely obscured by fume over the past several days, and the only consistent views have been with a thermal camera, which can "see" through the fume. This thermal image was taken at a nearly vertical angle from a helicopter, in order to see the bottom of the extremely deep and narrow vent cavity.

Lava was reaching heights above the tree line.

Lava from the erupting fissure produced a large flow that is moving southeast through the adjacent forest.

With lava retreating deeper into the Halema'uma'u vent cavity over the past two days, the cavity walls have experienced more frequent collapses. At 2:23pm today (March 7), a collapse from the upper portion of the vent cavity produced a robust brown plume, but did not eject any large particles.

On the west end of the fissure system, spatter ramparts are forming as the lava fallout solidifies in a mound upwind from the source.
