Kea is kay-a, not Kia. The pit craters are another feature that reminds us that lava is inflationary. It inflates, fills, drains and can leave a void that propagates upward as overlying material falls in.
I love this channel. I've never been so interested in Geology though admittedly I'm mostly here for the volcano stuff. Great work on covering all the interesting topics. You really earn my click every time with good topics and titles on your videos. The content is top notch to match which is like a perfect combo here on RUclips. You're going to go far keep up the good work. I'd love to see a video about how the grand canyon was carved if you ever were to do other geological content. It's taken me a very long time to understand it and I've only seen one video that every explained it satisfactorily and that was PBS Nova I believe. Anyway great work cheers 🥂
I am glad that you enjoy my content! I also have an eventual video planned on “fake” shield volcanoes that form in a manner similar to fake cinder cones, aka littoral cones
When I interned at HVO, I once visited the Devil's Throat pit crater just south of the Kilauea caldera along Chain of Craters road. It's a terrifying feature, deep, but also with an extremely small diameter, and it opens up a bit as you go down, so when you're standing on its edge, you know there is void space just a metre or two beneath your feet (and it's a long way down). Very cool place, the Hawai'i Volcanoes National Park. Lots of textbook volcanogenic landforms to explore, and the youth of the volcanoes means that erosion hasn't obscured most of them. Everything from hornitos and tumuli to littoral cones and tree molds are accessible to the determined hiker and volcanophile. Everyone should visit at least once in their life.
Dang - I wouldn't be messing around with any "void spaces" only a meter or 2 beneath my feet. That's tempting fate. Fate's already got enough temptations. Ms.Pele might be happy to oblige some day. I got to visit a cinder cone outside of Hilo many years ago. It was awesome. Stay safe out there.
Yes I agree with you about visiting Volcanoes National Park. I went to Volcanoes National Park last January. Even though that I had arrived at about midnight. I got up and went to Volcanoes National Park and I witnessed the orange glow coming from Halemaumau Crater. This is was a sight that I will never forget.
Void spaces moving upwards like that can also happen in mines. If the void space is small or deep enough, the swell factor of broken up rock will eventually fill the entire hole before it reaches the surface and stop its upward migration.
Thats why I have Mine Subsidence insurance. Theres an old mine shaft 2 miles below my house but that could give way some day in a similar fashion as this so, i have insurance in case that ever happens
This is exactly the way Etna's Bocca Nuova formed. Only this time, the magma at the bottom of the pit was still active. The crater started its life as a 10m wide vent in 1969, which was spewing flaming gas and some ash, but no lava. A few month later, it started widening by collapse into the gigantic crater it us today, intersecting Etna's Central Crater. South east crater also started its life as a pit in 1971, caused by withdrawal of magma from a large scale flank eruption. This was quite atypical though, as the eruption gases concentrated at the top of the magma column and turned the pit into a violently explosive ash vent.
Devils throat is quite impressive when you are standing on the edge! There are no marked trails only an app that takes you bushwhacking thru the ohia forest….it isn’t very far at all from road but not marked….I’m glad you mentioned two pineapples gave you permission to use his footage🤙
The earth is amazing... There's a moving mud pit near Salton sea in CA, heading towards San Andreas or walker Lane. Thank you for this video.... Interesting to see it's being pulled in three directions. I visited the island in pre lava activity, I have family in Hilo.
Could it also mean the roof collapse of a large Lava Tube? Perhaps there might not be any history of Lava Tubes being created on the island to support this theory.
There are many lava tubes on the Big Island. There is a large one near Waikoloa that has skeletons in it. Hawaiians still place offering of fruit and flowers in it.
@@karlr750 Our Undara Volcanic Precinct in Queensland, Australia has just over 160km of lava tubes. That's why I thought it might have been a similar event. Undara was a Sheild Volcano.
Interesting to finally hear something about that mysterious sinkhole. I first heard about it ten years and always wondered what this is. It was there even before 2015, but smaller. The Hale Pohaku staff has known about it for a long time. As far as I know, nobody has ever been down that pit crater, which is now fenced off. And Google Earth seems to have erased it from their images.
@@marenpurves4493 Maybe it's that other sinkhole I had heard of. I can't see another one on Mapquest, but you're right, it's supposed to be within walking distance of HP.
Because I'm likely to assume that the majority of lava tubes from eruptions older than 4k years that are going to collapse would have done so. Especially from the near constant low level seismic activity of the island making thin roofed tubes unstable
I live about 5 miles due East of Kīlauea, relieved to see that the rift Zone runs several miles makai but my question is what is known about complete rift zone collapse where it shears off an entire side into the ocean?
Lots is known about this. Hawaiian volcanoes do have a history of slope failure. The most spectacular examples are the north coasts of Oahu and Molakai -- those failed catastrophically hundreds of thousands to millions of years ago. There was also some instability off the west coast of the Big Island -- that's why the road between Ocean View and Captain Cook is full of curves and the slope so steep. The situation is a bit different at Kilauea. That is a slump, which is a very slow-moving slide, as opposed to a "locked" region that is in danger of collapsing. The coastal area is moving seaward by a few inches per year due to slip along a fault that lies beneath the volcano -- that's the same fault that slipped and caused strong earthquakes in 2018 and 1975. There's no indication it will fail catastrophically, and it is very well monitored by GPS, which would pick up any changes in rate. But it is a source of earthquake hazard, as the past strong seismic events indicate.
Are you referring to the pit crater next to the Mauna Kea Access Rd (19.775654, -155.450999)? If you are, that crater has been there before 2002. It shows up on Google Earth's 2002 satellite image.
Rift zone pit craters - your description of the "void spaces" sounds like a description of bubbles moving up through a fluid. Like a pikelet or fluffy pancake cooking on a skillet before you turn it over

There is a similar and larger crater in Las Pilas main volcano, Volcán Del Hoyo, in fact the name of that volcano is due to that crater (Volcano of the hole)
''A Mysterious Crater Just Formed'' ..... Eight Years ago. To a Geologist this is moments ago. To anyone else this is nearly a decade and surely old news.
Thank you for this video because I learned about something new! I would not be surprised if Mauna Kea did erupt again because there are small flank eruptions sometimes. I did not witness this flank eruption because it happened overnight, but there was a hole in a tiny hill on the side of the mountain when I woke up that morning. I do have photos of Mauna Kea and it was one of my dad's favorite mountains, probably because it was where he worked for so many years. Was the pit crater caused by an earthquake or is the mountain starting to collapse? Maybe they should send those cave scientists to go in and take a look around to find out the cause of it. Are there video cameras and seismic stations on Mauna kea? If there are, then scientists should see if there is any footage of how the pit crater formed. If not, then they may want to place them by the pit crater and keep track. Please keep us updated if you can. Thank you and happy holidays!
Mauna Kea hasn't erupted for 4600 years. This crater has been there for a while, but it was only a few years ago that the surface finally caved in and it was visible from the surface. The volcano is monitored by traditional sensors, like GPS and seismometers, but some of the best monitoring is via the telescopes at the summit. If there even very small changes, the telescopes would detect them.
Is there a plan to study and evaluate the origin of the new opening? Since its appearance is so new, it should be easy to catalog and monitor in the future.🤔
Hopefully you will get some good images of the pit crater! Two Pineapples (the individual who runs the RUclips channel) also expressed an interest in visiting the feature. Of course, I am unaware of if the NPS or local authorities allow access to it. They might not allow access for all I know. The crater showcased in this video does appear to be in the Mauna Kea Forest Reserve. Unsure of access or restrictions/rules surrounding it. Be sure to check whoever operates / controls access to the forest reserve and ask them before visiting it.
@@GeologyHub Now that the Mauna Loa eruption stopped there won't be so many people around. I'll wait for summer. Pretty cold right now 🙃 If there is a fence that will suck.
Coordinates based on Apple Maps and Google Earth imagery appear to be approximately: Coordinates: 19°46'14.41"N, 155°26'32.04"W (If you have an iPhone the feature shows up on apple maps if you turn on satellite imagery)
@@GeologyHub Found it right after I posted the comment. It doesn't show on google but I know the location. Steep area of the mountain. Android user but I know the island fairly well so it was easy finding the area visually. I've never been a big GPS user. Everything is by landmarks and memory.
Took my drone up today and got some photos and footage of the crater*. It's definitely not eruptive. The sunlight didn't reach the bottom by the time I got there due to the angle, but I could still make out rocks and features on the crater floor while flying overhead; I'd estimate the depth is slightly larger than the width (but not hugely so), and it's possible that the void extends back from the edges a bit. Someone's gone and put a fence around it, which dampens the discovery excitement somewhat, but it's still really cool to get to explore a new feature on a mountain I know so well. 😁 *Happy to share, though my camera lens fogged up a bit near the end so it's not all the greatest.
Going by the rate of expansion of the kiluea pithole, the process seems to be rather quick once it reaches the surface, despite there being no more material to press downwards. My amateur volcanic spider sense tingles at the odds at play here.
Once it reaches the surface, there's a corner to erode, which tends to be easier than eroding a roof. I bet weathering also starts to play a huge role.
But is there way to tell the difference as to which of the two ways this new crater was caused? They'll seemingly look the same on the surface but underground, the source is different
When was this discovered? If I had known about it when I was there, I would have sought it out. Maybe next time. I'm sure it's fenced off or whatever by now.
For a future video, could you cover a top 10 list of volcanoes around the world, most likely to erupt effusively within the foreseeable future which would be a draw for volcano chasing tourists?
I wondered why our local shield volcano Aden Crater had a deep pit in its crater that was a lava lake that cooled. I thought if it was a cooled off lake why is there a deep pit in it? It is a rifting zone, the Potrillo Volcanic Field with its famous 1.5 by 2.1 mile by 433 feet deep maar Kilbourne hole. I've been out there you can drive around the area and Kilbourne Hole is huge when you see it in person. Aden Crater by contrast is small.
It formed in the same way that Mauna Loa's summit pit crater formed. Lava probably was not evenly distributed underneath the volcano, and when part of it drained away in an eruption, a specific section collapsed. Could also have formed if the lava underneath the pit crater erupted within another section of its summit caldera.
i was wondering if you could do more videos about things in oklahoma i know we don't really have much of interest here but it'd be nice to see my home state on here more
@@relwaretep can't afford patreon right now literally don't have a spare dollar at all these last few months repair and vet bills are expensive as hell
Since everything above the hotspot is moving to the Northwest doesn't that mean these occurrences will happen less and less over time? I don't foresee a future occurrence of an eruption on Mauna Kea. It appears to have moved off the hotspot, as opposed to Mauna Loa to the south which is still near or at least nearer to the actual location of the hotspot.
The ground surrounding volcanic activity is so fragile craters conform from collapsing rock yep the volcanic vents when active are resilient enough to hold together as magma is forced thousands of feet into the air. Magic rocks!
So newly added photos to google earth show Satellite photos from as late as June 2019 show that the sinkhole was not there. So this sinkhole is newer than once thought.
A similar chimney collapse effect occurs after underground nuclear explosions. If you look at satellite photos of the Nevada nuclear test site, you'll find hundreds of shallow craters formed over the locations of underground tests. The explosion makes a spherical void, which then migrates upward as the roof collapses.
Probably not in most cases; there are signatures like ejecta patterns, raised rims and terracing, brecciation and melting, unusual compositions and e.g. shocked quartz that make most meteoritic craters unique and unmistakable when taken together.
At first glance a pit crater could be mistaken for an eroding meteorite impact crater. Lack of supporting evidence like shocked minerals, ejecta like tektites, etc. soon point to another reason for the crater.
Great question , keep asking question like this. If I may , you might find this interesting if you are interested in crater and old impact. Forgotten Civilization: The Role of Solar Outbursts in Our Past and Future
Wow, that's pretty cool! Just when you think you know a mountain. Hmm, that might be reachable...if it stops snowing and breaking windspeed records at the summit. 😄
A bit of advice: It's pronounced more like "Mowna-kay-a" than "Mauna-key-a". Vowels in written Hawaiian are pronounced very much like the vowels in written Spanish. A Hawaiian "e" generally has a hard "a" sound like the e in "hombre". Great geology though!
It is pronounced Kay-uh, not Key-ah. Mauna Kea. The Hawaiian language has its own rules of pronunciation that are not necessarily the same as the English language.
So there's no chance this is a "crater" created when water erodes the layer underneath a former lava tube causing it to collapse like a sinkhole like Califorina?
Kea is kay-a, not Kia. The pit craters are another feature that reminds us that lava is inflationary. It inflates, fills, drains and can leave a void that propagates upward as overlying material falls in.
I served on a US Navy ship called the Mauna Kea in the early 80's. I also served on the Haleakala. Both ammunition ships.

The ground surrounding volcanic activity is so fragile craters conform from collapsing rock yep the volcanic vents when active are resilient enough to hold together as magma is forced thousands of feet into the air. Magic rocks!
It’s pronounced kaya. The vowel e in Hawai’ian is pronounced like an ‘a’. Thought you might like to know
So newly added photos to google earth show Satellite photos from as late as June 2019 show that the sinkhole was not there. So this sinkhole is newer than once thought.
Ask a geologist. Even I an amateur would initially think it’s an old lava tube ceiling collapse.
A crater just formed... 7 years ago.
A similar chimney collapse effect occurs after underground nuclear explosions. If you look at satellite photos of the Nevada nuclear test site, you'll find hundreds of shallow craters formed over the locations of underground tests. The explosion makes a spherical void, which then migrates upward as the roof collapses.
I wonder if this might be what is happening at places we are calling ancient meteorite craters?
Probably not in most cases; there are signatures like ejecta patterns, raised rims and terracing, brecciation and melting, unusual compositions and e.g. shocked quartz that make most meteoritic craters unique and unmistakable when taken together.
I’m sorry what?
At first glance a pit crater could be mistaken for an eroding meteorite impact crater. Lack of supporting evidence like shocked minerals, ejecta like tektites, etc. soon point to another reason for the crater.
Great question , keep asking question like this.
If I may , you might find this interesting if you are interested in crater and old impact.

@@Imbalto Impact makes a splatt. Try it with a rock in mud.
A pit crater collapses downward and has no splat to it.
Wow, that's pretty cool! Just when you think you know a mountain.
Hmm, that might be reachable...if it stops snowing and breaking windspeed records at the summit. 😄
I'm interested in a study of a flank collapse like la Palma was supposed to do
It just formed? No, it formed 6 or 7 years ago. I watched thinking it was new and maybe had something to do with current eruptions.
thank you
It's Mauna "Keh-a", not "Key-a".
Very interesting
Mauna Kea actualy last erupted from nov27 -- dec13 2022 and this was uploaded after that
My weird brain made me think of electron hole theory when watching the animated dynamics.

Why would I put bullet holes in my ceiling?
@@whiteknightcat @FirstDagger was talking about tequila shots not shooting a gun.
@@wolfmama7879 OK then, why would I want tequila all over my ceiling? LOL
I'm sure geology hub would love to be the source of a drinking game.
A bit of advice: It's pronounced more like "Mowna-kay-a" than "Mauna-key-a". Vowels in written Hawaiian are pronounced very much like the vowels in written Spanish. A Hawaiian "e" generally has a hard "a" sound like the e in "hombre". Great geology though!
thanks
so its basically like a water bubble except much slower
Interesting.
It is pronounced Kay-uh, not Key-ah. Mauna Kea. The Hawaiian language has its own rules of pronunciation that are not necessarily the same as the English language.
So there's no chance this is a "crater" created when water erodes the layer underneath a former lava tube causing it to collapse like a sinkhole like Califorina?
Not to be confused with a lava tube collapse I assume..
It's pronounced Mau-na Kay-ah,
NOT Mau-na Key-ah.
If the volcano would be in sweden, it would be called Mauna Ikea 😂
Ummmm what’s Mouna Kia ???????
Pronunciation Not Kia like the car . Kea like your the letter K . Born raised Hawaiian
The way the mountains are pronounced 😅 thanks for the Hawaii attention but this was funny
Could you make the audio any worse? I'm sure if you got a few more demented sound engineers on your team you could accomplish that.
Not Mauna Kee-a. It's pronounced Kay-ah, Mauna Kay-ah.
Kea ----- kay-uh not kia
20 bucks says Godzilla gonna poke it's head outta there at some point
pit craters are likely on mars, and the moon. or, more accurately on any body that experience any type of volcanism
I wonder how big the Hawaiian land mass will be in let's say 10-20k years from now?
Lots of property for sale, but no breathable air. Oh well.
Using this logic, does that mean the pit crater will eventually disappear?
O Mauna Kea might wake up for the last time or just a sign the volcano is eroding
Ghidorah? Better be watching that hole, just in case.
It means get out. Yes Hawaii is beautiful. So are lions, tigers, and bears. That doesn't mean live with them.
