Video: Kilauea Eruption’s Spectacular Return
After giving the world a lovely early midwinter gift with the first eruption of Mauna Loa in 38 years, Madam Pele took the holidays off. Kilauea’s summit eruption paused on December 9th, possibly due to the relief of stress as its neighbor’s reservoir emptied.* Mauna Loa’s display ended on the 13th, and both volcanoes slumbered peacefully through the new year.
Pele returned to Kilauea with a spectacular lava show on January 5th. And I’ve got the videos all nicely arranged for you.

2021 was an excellent year for eruptions that were fascinating to watch and not terribly dangerous to humans! Let’s look back on the eruptions we covered, and see where they are now, and what might be in store for 2022.
Kilauea, United States
Tūtū Pele has celebrated the last couple of New Years with sweet summit eruptions. From late December 2021 through most of May of 2021, we were treated to a spectacular end to the water lake in the crater and entertained by the dancing islands of the new lava lake. Pele took the summer off before abruptly returning on September 29th. She’s been putting on a crater lava show ever since, with just a few breaks, including a pause over Christmas. By the new year, she was back in action and put on a lovely show over the holiday.
Since Pelee’s only taken one year off since the 1980s, I’m expecting this year to include some gorgeous lava action from her current home. And stay tuned to see if she does any remodeling at Mauna Loa!

A Kilauea Thanksgiving
Hello, my lovely people! It’s American Thanksgiving, and hopefully most of us subject to it have survived without too many kitchen mishaps and family feuds. If you’ve spent it alone, I hope you’ve had a lovely bit of solitude. And for those of you who, like me, worked the day, I hope everything went as smoothly as a holiday can.
Let us give thanks to Tūtū Pele, who has provided us with this lovely and relatively safe ongoing eruption in her home on Kilauea volcano:

A few days ago, I noticed a fairly large although fleeting increase in the output of lava from the summit vent. According to the USGS, it lasted just a few hours, and then all went back to the current normal. But it sure did look neat in the summit webcams! I grabbed the relevant bits and slowed them down for you.

Madame Pele Breezes Back In

Allow me to set the scene: bugger-all was going on at Kilauea Volcano. Madame Pele had shut up shop in May and taken a luana iki (little rest). Perhaps she paid a visit to Iceland’s bouncing baby shield volcano. She may have stopped by La Palma to give her cousin some encouragement.
Back at Kilauea, there were a few rumbles in late August, with an intrusion of magma to the summit. But after that delivery, nothing much happened for most of September. It seemed to many that Pele’s luana iki might turn in to a long winter’s nap.
Madame had no such plans.

The Lowdown on LAZE: La Palma Eruption’s Most Recent Hazard
The lava flow from La Palma’s ongoing eruption has reached the Atlantic Ocean. The news is full of people talking about how hazardous this is: you can get all kinds of explosive interactions between water and molten rock. There’s also the little matter of LAZE. Now seems like the perfect time to bring you this article, first published at Scientific American Blogs, telling you what to expect from those dense white plumes.
And I’d also like to take this opportunity to remind you why it’s a terribad idea to sail too close to an ocean entry. Keep your distance!
Kilauea’s most recent lava flows reached the sea over the weekend, and they’ve been beach bumming ever since. Few things are as dramatic as molten rock contending with seawater. We’ll be talking about all the neato things that are happening and that we may see if the eruption continues. We’re starting with LAZE, which in this case isn’t something you do on a hot summer afternoon. It’s this:

When blazing hot lava meets seawater, the interaction between them boils the water and produces enormous plume of mist, called LAZE (lava haze). These plumes are, of course, mostly water vapor, but they are so much more than that. They’re acidic beasts carrying appreciable amounts of hydrochloric acid, hydrofluoric acid, sulfate anion, carbon dioxide, and nitrogen dioxide, plus traces of volcanic glass and other particles. Even if you could find a safe place near where the lava is pouring into the ocean, you wouldn’t want to be hanging out there without industrial-grade protection.
Sounds super scary, right? Well, it’s concerning. But don’t panic. It, like so many of Kilauea’s other dangers, is something you can protect yourself against with a little common sense and caution. And it’s really pretty neat. (more…)
Kilauea Erupts! R.I.P. Kilauea Water Lake. Viva the Lava Lake!
Madam Pele awakened rather abruptly on the night of December 20th, 2020, and decided that water lake in her crater just had to go. Volcano goddesses remodel in a spectacular fashion.

Lakes are temporary features, geologically speaking. Some lakes are more temporary than others. When a lake makes its home in the crater of an active volcano, its life can be very short indeed. And what takes months or years to create can take only hours to destroy.
