Kīlauea Volcano — Kapoho Ocean Entry

An aerial view of the Kapoho ocean entry, as of 6:30 a.m. HST today, shows the extent of the lava delta, now about 200 acres in size, that has formed over the past six days (lava first entered the ocean on the night of June 3). Across the front of the delta, plumes of laze—created by molten lava interacting with seawater—appeared diminished this morning, but was probably

Kīlauea Volcano — Halema`uma`u Cracking and Slumping

Cracking and slumping of the Halema‘uma‘u crater walls are clearly evident in this aerial view captured during HVO's overflight of Kīlauea's summit this morning. Steam plumes have been rising from within the crater, as well as from cracks adjacent to the crater.

Kīlauea LERZ lava flows and fissures, June 9, 10:00 a.m.

Map as of 10:00 a.m. HST, June 9, 2018. The fissure 8 flow has created a lava delta approximately 200 acres in size, filling Kapoho Bay and shallow reefs along the nearby coastline.
Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown

Kīlauea Volcano — Halema‘uma‘u Cracking

Another aerial view showing prominent cracking around Halema‘uma‘u from the ongoing subsidence at Kīlauea's summit. The steaming cracks in the background have been observed for several days.

Fissure 8 and lava channel in the lower East Rift Zone of Kīlauea Volcano during this afternoon's overflight, with no apparent slowing in the eruption rate. The lava channel remained incandescent all the way around Kapoho Crater before entering the ocean.

Kīlauea Volcano — Summit Outgassing

Outgassing from Halema‘uma‘u produced twin pillars that rose in the still morning air and merged into a towering cap above the summit of Kīlauea just after sunrise.

Kīlauea LERZ lava flows and fissures, June 8, 12:00 p.m.

Map as of 12:00 p.m. (noon) HST, June 8, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

Characterizing earthquakes is one of the most important activities we do at the USGS Hawaiian Volcano Observatory (HVO). Seismicity helps us monitor the "pulse" of volcanoes and can be a first indication of an impending eruption.

Visitors to the Jaggar Museum and Ka‘ū Desert in Hawai‘i Volcanoes National Park, struck by the appearance of three dark, symmetrical volcanic cones on the western slope of Kīlauea Volcano, often ask "what are they?" and "why are they there?"

In early September 2016, USGS Hawaiian Volcano Observatory (HVO) monitoring instruments on Kīlauea began recording increased rates of inflation and slightly elevated shallow earthquake activity. These changes indicate a higher rate of magma accumulation within the volcano's summit magma reservoir.
