30 years of Volcano Watch - USGS Volcano Watch

It’s hard to believe that the “Volcano Watch” weekly article and volcano activity update started 30 years ago. On November 3, 1991, the USGS Hawaiian Volcano Observatory (HVO) “Volcano Watch” had its debut in the Hawaii Tribune-Herald, beginning a long and fruitful partnership. David Clague, former HVO Scientist-In-Charge, initiated this series of weekly articles in late-1991. He was the primary author until March 1995, when the HVO staff—and eventually other partners—began contributing. Clague recently commented, "I did not think I would be starting a weekly newspaper column that would continue for 30 years. [Volcano Watch] has exceeded my expectations in longevity and has served Hawaii well by teaching the populace about how Hawaiian volcanoes work, but more importantly, about how science and the scientists who do it constantly incorporates new observations and ideas to improve understanding." The “Volcano Watch” started as a weekly eruption and earthquake update to inform the public about the activity taking place at Pu‘u‘ō‘ō and Kupaianaha, which were erupting in the middle East Rift Zone of Kīlauea. These updates provided the public with current information that didn’t warrant a Press Release. Occasionally, they included lava flow field area or earthquake location maps. Short articles addressing volcano-related topics of interest to the community were added before the “Volcano Activity Update” section in 1992, the forerunner of our present-day format. Over the past 30 years, many subjects have been highlighted in these articles ranging from volcanic activity and processes, earthquakes, monitoring techniques, HVO staffing updates, and much more. Topics are typically focused on Hawaiian activity, but also include interesting observations about global volcanism and seismicity, news from other USGS volcano observatories, and some additional special topics. Thirty years’ worth of articles have formed a treasure trove of information that can be used as a reference for almost any volcano-related questions you have. In addition to the articles being printed in the Hawaii Tribune-Herald, the full “Volcano Watch” archive of more than 1,500 articles is available on the HVO website. HVO staff have written most of the articles, but there have also been numerous contributions from volunteers, other Volcano Science Center staff, university partners and affiliates, and the USGS Pacific Island Ecosystems Research Center (PIERC). The effort put into the “Volcano Watch” has not gone unnoticed. In November 2000, the “Volcano Watch” received a Customer Service Excellence Award from the U.S. Geological Survey for communicating science to a diverse audience. The National Association of Government Communications awarded the HVO “Volcano Watch” column First Place in the Electronic Publication category during the annual Blue Pencil and Gold Screen award program on June 26, 2019. Since the founding of HVO in 1912, a large part of our mission has been to communicate science, volcanic activity and earthquake updates, and hazards to the public, emergency managers, and other scientists. HVO has published many different informational products over the years to keep the public informed, but the “Volcano Watch” remains one of the longest-running and timely series. “The Volcano Letter” was a collection of short scientific articles along with volcano activity and earthquake updates started by Thomas Jaggar and published monthly from 1925 to 1955. After this publication was terminated in 1955, HVO no longer had regularly scheduled, publicly available volcano updates. A few short-lived products, similar to “Volcano Watch” were written by HVO, news outlets, and other scientists, however none lasted for more than a few years. The most notable of these short-term publications, titled “Volcano Watching,” was written weekly by Bob and Barbara Decker, while Bob was a geology professor at Dartmouth. These ran in the Hawaii Tribune-Herald from July 1978 to February 1979, but stopped when Bob became Scientist-in-Charge at HVO. When David Clague restarted the “Volcano Watch” in 1991, it filled a void in HVO’s public communications. Before the USGS began releasing volcano updates through the Volcano Notification Service (VNS) in 2006, the “Volcano Watch” updates kept residents apprised of weekly changes that were not substantial enough to issue a Press Release. “Volcano Watch” articles continue to be an important and timely means of distributing information to both local and global audiences. HVO’s founder, Thomas A. Jaggar, believed—as we do now—that effective communication of volcanic hazards and eruption information, especially to the residents of Hawaii, is crucial.

Interesting. I had not realized that it hadn't been there before 1991.

Help Ken Boyer in His Recovery Journey

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
