When Whirlwinds Meet Hot Lava: Lava Devils!
There are so many things to see while watching a livestream of a volcanic eruption. Lava fountains, spatter cones being built up and falling down, turbulence in lava flows… and lava devils?!
Yes, indeed! Keep your focus on the left in the video below, and you’ll see molten lava sucked up and flung about by a vigorous little whirlwind during Kilauea’s latest summit eruption: (more…)
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.
The Year in Volcanoes at Rosetta Stones
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.
Here ’tis in the thermal cam: (more…)
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.

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.
Rainbows Over Geology
Are you ready for some spectacularly beautiful images? It’s a tough time: of course you need some beauty in your life. Allow me to provide!
In between pandemic lockdown preparations, I’ve been spelunking the USGS website and watching the OG Knight Rider. K.I.T.T. is absolutely marvelous, but not quite as beautiful as some of these images I’m finding. USGS scientists are pretty talented photographers! And while most of the photos they take in the field are for strictly scientific purposes, they also turn their lenses to capture the ephemeral beauty that happens geology and meteorology combine.
I’ve lightly edited these photos to enhance their awesomeness. You can click the link in the titles to see the originals.
A Must-Have Book for Lava Loving Kids: What’s So Hot About Volcanoes?
Having enjoyed Wendell A. Duffield’s Chasing Lava immensely, I was beyond delighted to discover that Wendell had written a book for younger people. I couldn’t order it fast enough.
What’s So Hot About Volcanoes is a fantastic choice for anyone looking for a book about volcanoes for older kids and tweens, or even adults who want an authoritative but not too technical introduction to how volcanoes work. Younger readers should be able to handle it, too, with assistance from older kids and adults. And it’s got a hook absolutely no one can resist: what happened to Wendell when he was standing on a fresh Kilauea lava field and the seismologist at Hawaiian Volcano Observatory told him the pattern of seismicity right underneath him suggested he should probably run away immediately!
Chasing Lava: A Fun and Fascinating Memoir of Hawaiian Volcanology
If you’re looking for a light, breezy, but informative book about volcanoes from a genuine volcanologist, I’ve got it right here for you. Chasing Lava: A Geologist’s Adventures at the Hawaiian Volcano Observatory by Wendell Duffield is a delightful memoir of his years working at the Hawaiian Volcano Observatory. There’s a wonderful sense of adventure infusing the whole book, and he gets us up close and personal with Madame Pele’s handiwork.
Newly-hatched USGS geologist Wendell, his wife Anne, and their pets were stationed on the Big Island from 1969-1972. He worked on Kilauea Volcano at a time when the theory of plate tectonics was still brand new, our instruments were still bulky and somewhat primative, and volcanoes were much less understood than they are now.
