Aloha to the University of Hawai‘i's Newest Geology Professor — Volcano Watch

USGS Hawaiian Volcano Observatory — Dr. Lis Gallant has spent the last two and a half years at the USGS Hawaiian Volcano Observatory (HVO) as a National Science Foundation Postdoctoral Fellow studying the lava and cinder cones from the 2018 eruption of Kīlauea. She is making a short move up the hill this week to join the Department of Geology at the University of Hawai‘i Hilo (UHH) as an Assistant Professor. Volcanology was not always on the horizon for Lis when she started her academic journey in Troy, New York. She took courses at Hudson Valley Community College before receiving a Bachelor’s degree in Electronic Media, Arts, and Communications from Renssealer Polytechnic Institute. After several years working in the medical software industry, she returned to school and received a second Bachelor’s in Geology from Buffalo State University. As an undergraduate student Lis conducted research on tephra deposits of Santa Ana Volcano in El Salvador, which helped her discover a passion for science with real-world application. It was after this that Lis first came to the Island of Hawai‘i to work at HVO as an intern mapping lava flows on Mauna Loa and assisting in Puʻuʻōʻō eruption response from 2012 to 2013. Lis then went to the University of South Florida (USF) to pursue both a Master’s and PhD in geoscience. Her work focused on developing new computer-based lava flow hazard assessment tools. Lis also expanded her skill set by working with different kinds of radar to study subtle changes in the shapes of volcanoes and map eruptive deposits below the ground. In addition to her research, she was an avid teacher while working on her degree, instructing numerous courses and assisting with USF’s summer field courses. She taught students from Florida—many of whom had never seen mountains before—to map folds, faults, and geologic deposits for the first time! While at USF, Lis was part of the response to volcanic unrest at Nevado del Ruiz, in Colombia, and the eruption of Momotombo in Nicaragua. These experiences further bridged the gap between academic research and applied science, which set Lis on her path after she graduated with her PhD. Thereafter, Lis moved to the United Kingdom in 2020 and joined the IMAGINE project at the University of Cambridge Department of Geography. Although the COVID-19 pandemic prevented her from traveling to Chile and Argentina to examine the human and environmental geographies in these volcanic regions, she was able to forge strong connections with her colleagues and she looks forward engaging UHH students in this network. Lis returned to HVO in 2021 and continues to engage in both exciting research and eruption response efforts. She has helped respond to the 2020, 2021, and 2023 eruptions of Kīlauea and the 2022 Mauna Loa eruption. Lis brought several pieces of novel scientific equipment to study the volcanoes, including a magnetometer mounted on an uncrewed aerial vehicle, a ground penetrating radar, and a special radar that can detect rapid changes in the shape of the landscape (a terrestrial radar interferometer—TRI). The TRI was deployed during the waning phases of the Mauna Loa eruption. The flow front was difficult to continuously monitor due to inclement weather and logistical constraints of working at high altitude. Lis and graduate students from USF successfully located the flow front in near-zero visibility conditions and were able to image flow thickening along the margins. Lis has continued to teach during her time at HVO. She is a faculty member for the GeoSPACE project, a field course that focuses on improving the experiences of disabled students in the geosciences. Her efforts were recently recognized by the International Association for Geoscience Diversity when they presented her with their Inclusive Geoscience Education and Research Award in 2022. Lis is excited to bring all of these amazing assets—passion for teaching, diversifying the geosciences, and volcano research—to her students as she begins her first semester at UHH. Although we will certainly miss her at HVO, we look forward to collaborating with her as a UHH partner. UHH has been an active partner with HVO for many years and this relationship will continue to thrive with the Department of Geology’s newest professor.

Help Ken Boyer in His Recovery Journey

Our friend Ken Boyer is facing some pretty serious health challenges right now. Ken was an early friend and contributor to Hawaii Tracker over 8 years ago now. Any support you can give him would be appreciated and please keep him and his ohana in your prayers! 🙏 If anyone would like to support Ken and his family you can do so at the link below. https://www.gofundme.com/f/liver-transplant-journey-recovery-nsvfc Here is the post Ken shared on social media today: "Hello my dear friends and family, this is gonna be a long one, sorry but I feel it’s time I share my story that very few know. The last few years have been extremely difficult for me and my family. We’ve suffered tremendous loss and I found myself feeling ill also. Very weak, extremely tired and fatigued, abdominal pain, unable to think clearly and at times not even being able to form sentences, unable to remember things, etc…I was very concerned and went to the doctor. After a series of tests and such I was ultimately diagnosed in November of 2023 with End Stage (Stage 4) Liver Disease (Cirrhosis) as well as several other related diagnosis, the worst being Hepatic Encephalopathy. Went to a few doctors to review the diagnosis. One was very hopeful and said may be able to get a transplant. Another said I had 6 months to live and it sure felt like it. Since then I’ve changed my diet, saw many specialists, been back and forth to Oahu and even to California. It is believed that this disease came on from a fall I had into stagnant water on a river back in 2008. At that time I contracted Leptospirosis. That was very difficult to navigate for quite some time but I did get better and I thought that was that. Apparently not… It’s heavily affected my ability to work. We tried many things attempting to keep Rico’s Taco Shop open but it just wasn’t able to operate successfully without me being present. My wife did an amazing job of trying to keep it going. She was just working herself to death though. She ultimately was able to secure a great job and I have since been unable to find a way to operate Rico’s. This has been crushing to us in so many ways. My dream business, emotionally, financially…. Needless to say, it’s been a roller coaster. This has pushed us to the breaking point in so many ways and continues to daily. The hardest part is what I see it doing to my wife and kids. They are amazing. My wife has been by my side through all of this and I can’t thank her enough for all that she’s done. The kids are affected a lot and it kills me. I don’t have the energy to be there with them and present like I’d like to be. They are strong. They know daddy has some health issues but don’t understand the extent of it. My oldest daughter is aware but living in the mainland at this time. Unfortunately the cirrhosis has progressed and has made it impossible to do much. A lot of days I’m unable to drive even. There’s been countless trips to the ER and stays in the hospital due to this as well as many procedures and medications. Currently I’m on 12 medications. I will need a transplant to live and I’m working towards that. However I will be having to move to either Oahu or California to do so. I’m working on getting disability but have been denied and have to keep pushing for it. My days consist of falling asleep at all times out of nowhere, even standing up. Or the opposite, extreme insomnia. The day to day of all the symptoms is overwhelming and I won’t bore you with it all. Some are very ugly too, you don’t wanna know lol. The cost of ongoing care has been a huge burden on us as well and we do need help there also, somehow. I decided I needed to be transparent about this. I owe it to you all. You’ve all been such amazing friends and family that it only seems right. I’m sure some have wondered “what happened to that guy, he used to always be online”. Well, I just can’t be like I used to be. Life has become very mundane. The last thing I wanted to do was ask for any donations. We’ve been trying to do anything and everything we can to sell off everything to raise funds. We’re just not nearly close enough and currently not able to cover bills even. But my main concern is being able to get to Oahu or California when the time comes for a transplant. Which will happen sometime in the near future. I don’t know any other way to make this a reality. We have a lot of loose ends here that we will have to deal with financially before it’s possible to even leave and once I’m there I’ll need to rent a place to stay. Medical should cover the majority of the medical bills. Depending where I go. If I have to go to California the medical will be different and won’t cover nearly as much. But Oahu doesn’t have nearly as many viable livers annually. So that’s where the concern is as to where I’ll be going. Either way, no matter what happens, if you donate, it will be going to the ongoing cost of care, travel, housing, and anything else that is going to be out of pocket. If you can help, that’s fantastic and I appreciate it more than I could ever explain but a share means just as much. Thank you all! I will try to get back with everyone as much as I’m able to. Even a prayer!!! Love you all 🙏🏼"

Episode 28

Update: Episode 28 of the ongoing Halemaʻumaʻu eruption ended abruptly at 1:20 p.m. HST on July 9, 2025, after 9 hours of continuous fountaining, the final 8 of which were high fountaining. The north vent stopped erupting at approximately 1:20 p.m. HST, marking the end of the episode. The south vent did not appear to activate at all during this episode and has been completely covered by new deposits. The growing cone around the north vent has begun to connect with the top of the surrounding cliff in some places. Lava fountains reached up to approximately 1200 ft (365 m) during this episode. Volcanic gas emissions have greatly decreased since the end of fountaining. Lava flows from this episode on the floor of Halemaʻumaʻu within the southern part of Kaluapele (Kīlauea caldera) may continue to exhibit slow movement or incandescence as they cool and solidify over the coming days. Slumping of molten cone material around the vent may also continue for the next 24 hours and can produce small, localized lava flows. The Uēkahuna tiltmeter (UWD) recorded about 15 microradians of deflationary tilt during this episode. The end of the eruption was coincident with a rapid change from deflation to inflation at the summit and a decrease in seismic tremor intensity. --------------------------------------- Episode 28 of the ongoing Halemaʻumaʻu eruption began at 4:10 a.m. HST on July 9 and is currently exhibiting a vent overflow and fountains reaching roughly 150 feet (45 meters). Past episodes have produced incandescent lava fountains over 1000 feet (300 meters) high that result in eruptive plumes up to 20,000 feet (6000 meters) above ground level. High fountaining associated with this episode has not yet begun but is expected to start soon, as tremor, deflation, and fountain height are all increasing. According to USGS weather stations just southwest of the summit, winds are blowing from the north-northeast direction at approximately 15 miles per hour, which suggests that volcanic gas emissions and volcanic material will be distributed south-southwest. Such trade winds typically turn more to the northeast during daylight hours. All eruptive activity is confined to Halemaʻumaʻu crater within Hawaiʻi Volcanoes National Park Three Kīlauea summit livestream videos that show eruptive lava fountains are available here: https://www.youtube.com/@usgs/streams

Episode 24

Episode 24

Episode 24 of the ongoing Halemaʻumaʻu eruption began at 8:55 PM HST on June 4 and is currently fountaining from the north vent. Episode 24 was preceded by sporadic spatter, gas pistoning, and hydrogen flames that began on the morning of June 3. At approximately 8:55 PM HST, episode 24 began with low dome fountaining accompanied by lava flows onto the crater floor. Small sustained lava fountains, less than about 100 feet (30 meters) high, began erupting from the north vent around 9:15 PM. Activity increased again around 10:10 PM, when fountain heights increased to 325 feet (100 meters) and by 10:40 reached over 980 feet (300 meters). Additionally, the fountain generated a plume that reached 16,500 feet (5,000 meters) above ground level by 10:50 PM and is increasing. At a tiltmeter near Uēkahuna (UWD), inflationary tilt reached just over 14 microradians since the end of the last episode; slightly more than the amount of deflationary tilt in episode 23. Seismic tremor began increasing and tilt at UWD switched from inflation to deflation at about 9:00 PM HST, close in time to the beginning of low fountaining. Most episodes of Halemaʻumaʻu lava fountaining since December 23, 2024, have continued for around a day or less and have been separated by pauses in eruptive activity lasting generally at least several days.

Episode 17 of the ongoing Halemaʻumaʻu eruption began at 10:15 p.m. HST on April 7, 2025 with the start of lava overflowing from the south vent. Low spatter fountains from the south vent have been increasing from initial heights of 15-30 feet to 30-60 feet by 3:00 am HST on April 8. Tremor continues to gradually increase as well and is accompanied by slow deflation of the summit. - USGS Volcanoes
