Comparison of photographs taken on June 13 and 26 from near Keanakāko'i Crater overlook in Hawai'i Volcanoes National Park shows a subsidence scarp that formed as the Kīlauea Crater floor subsided. Scientists estimate the dramatic dropping of the crater floor in this area occurred sometime between June 23 and 26. The view is to the west. Halema‘uma‘u crater is in upper

Kīlauea Summit UAS footage shows an ever growing Halema‘uma‘u

A UAS mission on June 24, 2018, filmed details of the dramatic changes occurring within Halema‘uma‘u crater at Kīlauea's summit since explosive eruptions of ash and gas and ongoing wall collapse began in mid-May. Clearly visible are the steep crater walls that continue to slump inward and downward with ongoing subsidence at Kīlauea's summit. The deepest part of Halema‘uma‘

Kīlauea Volcano — Documenting Fissure 8 Activity

USGS Hawaiian Volcano Observatory geology field crews maintain watch over the eruptive activity in the lower East Rift Zone and at Kīlauea's summit. Here, a geologist documents the behavior of lava as it exits the Fissure 8 cone. Lava enters the upper channel traveling as fast as 30 km/hour (18 mi/hour).

Lava is entering the sea on the southern side of the entry area primarily through the open channel, but also along a 1 km (0.6 mi) wide area. The entry areas are marked by billowing laze plumes. The interaction of lava with the ocean creates "laze", a corrosive seawater

The U.S. Geological Survey's Hawaiian Volcano Observatory (HVO) recorded a magnitude-4.3 earthquakebeneath the Island of Hawaiʻi on Friday, July 22, 2016, at 9:16 p.m., HST. The Pacific Tsunami Warning Center determined that no damaging tsunami was generated (http://ptwc.weather.gov/?region=2).

July 7, 2016

Two years ago, Kīlauea Volcano's "June 27th" flow advanced to the northeast, threatening Pāhoa and creating major disruptions to thousands of residents in the lower Puna district on the Island of Hawai‘i. Today, a new flow from Pu‘u ‘Ō‘ō is moving to the southeast along the boundary of Hawai‘i Volcanoes National Park and could eventually reach the ocean.

Readers of Volcano Watch might recall past articles that have described various ways in which the USGS Hawaiian Volcano Observatory (HVO) studies and monitors the active volcanoes of Hawaii. Today, we focus special attention on just one of those techniques: gravity.

The engagement of written history and geology, two ordinarily separated academic disciplines, has—once more—proven unexpectedly fruitful in our understanding of Hawai‘i’s natural environment.

Early on the morning of May 24, 2016, USGS Hawaiian Volcano Observatory scientists were alerted by text message that a tiltmeter on the Pu‘u ‘Ō‘ō cone on Kīlauea Volcano's East Rift Zone had detected rapid change. Soon after, an HVO field crew reported that lava had broken out from the flanks of Pu‘u ‘Ō‘ōO.

June 9, 2016

During the past 148 years, Mauna Loa Southwest Rift Zone eruptions have sent massive lava flows across Hawai‘i Island's main road six times: in 1868, 1887, 1907, 1919, 1926, and 1950.

Where (and how) you gonna go when the volcano flows?...
June 2, 2016

Island of Hawai‘i residents, especially those living in South Kona and Ka‘ū Districts, which are at particular risk from Mauna Loa's Southwest Rift Zone, might wonder where they're gonna go when the volcano erupts—even if it flows, rather than "blows." But, more than knowing where to go, a greater challenge might be how to get there.
