Episode 15 might be starting very soon!
Update: the cycles are continuing with gaps of about 4 minutes. I started documenting these not thinking there would be this many cycles before the main fountaining started on this episode 😂. I'm going to head to bed so I won't be filling any more of the data in tonight. Have a good night everyone and enjoy the show. Episode 15 might be starting very soon! The lake was just visible with a good bit of fountaining, and now has dropped down. This cycle will keep repeating until the more vigorous fountains are continuous and much higher. When will the large fountains arrive? We shall see! Nort... See more
Lava Fountain Reaches 700+ Feet
When lava stopped fountaining in the north vent, the south vent fountain increased in height significantly around 8am to possibly just over 700 feet as seen in this video!
Episode 14 Fountaining Underway
Update: Episode 14 is fountaining very high right now, as of 7:49am HST. It was way over the top of the crater rim! Sustained fountaining from Episode 14 began in the south vent at 6:30 a.m. HST, followed by the north vent at 6:50 a.m. HST. Fountain heights are reaching 400-600 ft and lava flows cover ~50% of the Halema'uma'u crater floor at 7:20am HST.
Episode 14 could begin significant fountaining soon and lava is starting to pour out the north vent right now. The small fountaining has been starting and stopping for the last several hours but it’s beginning to increase in size and frequency.
Episode 13 ended at 3:13 pm HST on March 11 when the south vent shut down. The north vent shut down 2 minutes earlier at 3:11 pm HST. Small amounts of lava drained from the south vent for a few minutes after fountaining stopped. - USGS Volcanoes
Thanks for the notice about 13! Hopefully family can make it up to see. Blessings to all of you!!
Episode 13 Has Started
Episode 13 has begun! According to USGS Volcanoes, Episode 13 started at 2:36 AM HST on March 11 with small lava flows from the north vent. Within 10 minutes, high fountains erupted, reaching 300 feet (100 meters) by 3:05 AM HST. By 3:20 AM HST, the north vent fountains grew to 400-500 feet. 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 of the ongoing Halemaʻumaʻu eruption ended at 10:37 am HST just after fountaining stopped at 10:35 am HST on March 5. The continuous part of this eruption lasted for just under 22 hours before pausing. - USGS
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 co... See more
