Meanwhile, lava flows from the south vent began at 3:12 AM HST, with fountains starting by 3:30 AM HST and hitting 200 feet by 3:40 AM HST. If this episode follows recent patterns, it will erupt for 13-22 hrs, or until somewhere between 4pm Tuesday afternoon to 1am Wednesday morning. 🤙

Episode 12 Underway

Update: lava fountaining started just after 2 PM HST Update: Lava stopped flowing into the crater at 8:04 am HST. Episode 12 has started erupting out of the south vent around 7:30 hst and lava is flowing into the crater! If you are considering driving up to the national park, I would probably wait to see if this episode starts to fountain before making the trek. It’s behaving differently than prior episodes. From USGS at 2:24 pm HST: "Episode 12 of the ongoing Halemaʻumaʻu eruption began at 7:30 a.m. HST on March 4 with sporadic small lava flows alternating between the south and north cones. The transition to continuous fountaining started at 2 p.m HST. The first morning lava flow came from the south vent and lasted for approximately 20 minutes. It was followed by another sluggish flow from the north vent at 9:33 a.m. HST that lasted for about 12 minutes. Small fountains within the south vent fed a third small flow beginning at about 12:45 p.m. HST, which continued until 2:00 p.m. HST, when fountaining began at the north vent. Fountains from the north vent were within the north cone and about 20-30 feet (5-10 meters) high at the start. By 2:20 p.m. HST fountains were reaching 150-165 feet (45-50 m) and are expected to grow in the next hour. Inflationary tilt reached just over 10 microradians since the end of the last episode; nearly balancing out the amount of deflationary tilt during episode 11. Seismic tremor began increasing and tilt at UWD switched from inflation to deflation at 2:00 p.m. HST, at the same time fountaining began. Each episode of Halemaʻumaʻu lava fountaining since December 23, 2024, has continued for 13 hours to 8 days and episodes have been separated by pauses in eruptive activity lasting from less than 24 hours to 12 days."

Watching Episode 10 With Family and Friends

I had the privilege of witnessing episode 10 with my three boys and our friend Josh this past week. It was one of the most awesome things we’ve ever witnessed. It’s easy to take events like this for granted, and even take our time with friends and family for granted as well. If you get the opportunity to see one of these eruptive episodes, I encourage you to check it out and take some loved ones with you! 🤙 Video by Elijah Finlay
