Volcano Watch: On the surface of Kilauea’s new landscape, a story is told

Kilauea’s 2018 summit collapse dramatically transformed the geometry and appearance of Halema‘uma‘u crater and Kilauea caldera. Last week’s “Volcano Watch” article described how the 2018 events impacted the magma plumbing system beneath the surface of Kilauea’s summit. This week, we’ll explore how the 2018 events impacted the geologic deposits on the surface.

Volcano Watch: Water was in Kilauea caldera before the 2018 summit collapse

On July 4, 2018, an observer at the Volcano House Hotel was watching the evolving collapse of Halema‘uma‘u Crater, 2.5 miles away. Suddenly, he did a double take, blinked a couple of times, but couldn’t erase the dark line descending the wall of Kilauea caldera above Halema’uma’u. Not knowing what it was, he dubbed it the “black streak.”

Volcano Watch: Kilauea Volcano’s summit water lake is 1 year old

On July 25, 2019, ponded water was first observed within Halemaumau at the summit of Kilauea Volcano. Over the past 12 months, the USGS Hawaiian Volcano Observatory (HVO) has watched this amazing body of water grow from a nascent pond into a veritable lake, the first observed within Kilauea caldera in at least 200 years.

Volcano Watch: HVO looking to install seismographs in your community

The Youth and Education in Science (YES) program at USGS in collaboration with the Hawaiian Volcano Observatory (HVO) is launching a community outreach and educational project called Bridging Local Outreach &Seismic Signal Monitoring (BLOSSM) in Hawaii. BLOSSM aims at engaging local students and communities through seismology.

Volcano Watch: A legendary part of the Wailuku River is again revealed

The “Hawaiian Sup‘pa Man,” demi-god Maui, had several adventures on the Wailuku River in the legendary past. He rescued his mother, Hina, who lived in the cave behind Waianuenue (Rainbow Falls), from Kuna, a threatening mo‘o (legendary giant lizard), eventually killing him and leaving his body as a small island in the pool fronting Hina’s cave.

Tech talk part 2: Schematic diagram of one HVO technician’s position

Last week’s “Volcano Watch” article introduced the role of “technician” at the USGS Hawaiian Volcano Observatory (HVO). This week, we present the introspective of Steven Fuke’s life (schematic diagram) as an “electronics technician” at HVO through his experiences, starting with his introduction to HVO.

M-4.6 earthquake shakes Big Island

The U.S. Geological Survey’s Hawaiian Volcano Observatory recorded a magnitude-4.6 earthquake beneath Kilauea Volcano’s south flank at 11:20 p.m. Thursday.

Volcano Watch: Electronic ‘doctor’ tracks health of monitoring stations

As part of Volcano Awareness Month earlier this year, “Volcano Watch” featured five articles focused on different roles at the USGS Hawaiian Volcano Observatory (HVO). These articles described the roles of “geodesist,” “Scientist-in-Charge,” “gas geochemist,” “seismologist,” and “geologist.” This month, we continue that series, focusing on the role of “technician.”

Volcano Watch: Extraordinary tenure ends for leader of Hawaiian Volcano Observatory

The extraordinary leadership of Tina Neal as Scientist-in-Charge (SiC) of the USGS Hawaiian Volcano Observatory (HVO) comes to an end this week, when she returns to the alaska Volcano Observatory after fulfilling her five-year commitment to HVO. David Phillips, HVO’s Deputy SiC, will take the helm until Tina’s successor arrives.

Volcano Watch: Assessing Kilauea’s SO2 emissions

If you were around Hawaii Island — or even other Hawaiian Islands, or Guam — between May and August 2018, you likely know that Kilauea’s lower East Rift Zone (LERZ) eruption released a lot of sulfur dioxide (SO2). But how much is a lot?
