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.
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.”
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.
On June 27, 1952, an eruption started at the summit of Kilauea Volcano, ending a period of quiescence that had lasted nearly 18 years.
As many people have noted, the last global pandemic was raging one hundred years ago. Kilauea was erupting 100 years ago, although it was certainly not quite as significant of an event on the world stage.
The past two years of “Volcano Watch” articles from late May focused on commemorating the 49th and 50th anniversaries of the Mauna Ulu eruption. However, the end of May has several other notable Kilauea eruption beginnings, changes, and endings. Here we reflect on some selected anniversaries spanning 1823 to 2018.
Two years after the start of the Kilauea eruption in lower Puna, lava from the eruption is still estimated to be only half-cooled.
An increase in seismic activity around the youngest Hawaii volcano poses no immediate danger to the Big Island, geologists report.
The mission of the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) is “to monitor, investigate, and assess hazards from active volcanoes and earthquakes in Hawaii, and communicate results of this work to the public, emergency managers, and scientific community.”
Many messages to AskHVO (askHVO@usgs.gov) request resources relating to geologic maps and geographic information systems (GIS) data. “Is there a map of a certain lava flow?” “Where can I find the associated GIS data?” All HVO and USGS publications are searchable at https://pubs.er.usgs.gov/, but this service is most effective if you already know what to look for.
Understanding the immediate causes of volcanic eruptions is necessary for timely warnings. The topic, therefore, is of great interest to volcanologists, and each eruption offers an opportunity to add insight.
The May 3, 2018, eruption of Kilauea volcano caused property damage worth $800 million and injured two dozen people —a catastrophe for the area, but nothing unusual for a volcanic event. But researchers now think there might be something extraordinary about the eruption, after all. Scientists at the University of Miami argue that record-breaking rainfall in preceding months may have helped trigger the blast.
Mount St. Helens was exploding! The first eruption in the Cascades since 1914-17 (Lassen Peak) started on March 27, 1980. April became a frenzied, exciting, challenging, sometimes frustrating, once-in-a-lifetime experience for several scientists with experience at the U.S. Geological Survey (USGS) Hawaiian Volcano Observatory (HVO), called on to measure the deforming volcano.
With heavy heart, the USGS Hawaiian Volcano Observatory (HVO) bids aloha to Janet Babb, outreach geologist and educator extraordinaire who retired from federal service in late March. Because of her dedication and guidance over the years, HVO is well-positioned to carry on a tradition of quality media and public engagement.
Nearly 6,000 earthquakes have been recorded in the past eight months beneath Kilauea’s lower Southeast Rift Zone near Pahala in Ka‘u.
Mauna Loa, the largest active volcano on Earth, has erupted, on average, every 5–6 years during the past 3,000 years.
The presence of water in Halema’uma’u has sparked an important discussion about what the pond means for future eruptions at Kilauea Volcano. There are no written records of water at the summit, so to guide the discussion we need information about magma-water interaction from deposits of the past.
In the past, HVO would occasionally post images of people collecting lava samples on our website. These photos usually featured a person (with little-exposed skin) holding a rock hammer, with a metal bucket nearby. The bucket contained water to quench the sample, solidifying the hot lava into a cold glass. Natural-fiber or heat-resistant gloves, and sometimes a face mask, protected the sample collector from heat radiating off the 2,100-degree lava. The hammer was used to scoop some of the molten material into the bucket, which would hiss and steam in reaction; more water would be added to cool down the sample so it could be placed in a cloth bag.
