The Geologic Oddity in Iceland; Kerid Crater

Within Iceland is a volcanic crater which is a popular tourist attraction. Known as Kerid Crater, it measures 558 feet or 170 meters wide and 180 feet or 55 meters deep and is filled with at its bottom with a crater lake. Yet, it is highly unusual as it is not a maar explosion crater like originally suspected for many decades. It is also not a caldera. Instead, it has a different origin which makes Kerid Crater a fascinating geologic oddity.

I had great fun visiting this feature in person in August of 2022. I would definitely recommend performing the short hike around the crater rim. Any questions about it or the broader Grimsnes volcano?

Epic video

[@1234j]

Excellent! How about a longer video on it, please??

[@sixthsenseamelia4695]

Check out eq swarm at Kawerau (Whakatane) NZ. 150 + tremors in 6 hours. You did a video on the region - New volcano forming underneath a New Zealand town. *March 1987 m6.3 Edgecumbe Earthquake. 1886 Tarawera eruption.

[@redmohawkguy1]

I also visited Kerid Crater in person when I stayed in Iceland last year. I thought it was like any other volcanic cone in Iceland when I was there and did not know it is such a geologic oddity, so thank you for the video explaining its formation.

[@mbvoelker8448]

So, just like a caldera, but tiny. Volcanoes are full of so many surprises.

[@jajssblue]

2:24 a plume rising 1km per day blows my mind! I had no idea a volcanic process could happen that quickly.

[@GeologyHub]

I’m basing that tidbit off of the august 2022 Fagradalsfjall eruption.

[@carolynallisee2463]

I have to point out that the name of this crater isn't Kerid, but Keri-eth. This is because the last letter of it's name isn't an English 'd' but an Icelandic letter that looks like a 'd' with a horizontal line struck through the upright, and is pronounced 'eth'. I learned this during a stay in Reykjavik, when talking to the hotel receptionist one day. She kindly explained about the unusual letters in their alphabet, of which this strange 'not-a-D' was one.

[@jefferyindorf699]

​@@tcp3059 no, eth, not thorn. Thorn looks like the result of the mating of lower case b, and lower case p.

[@OpaSpielt]

He wrote Keriđ in his picture at 4:06 If I see a đ, I speak it like an English th. Hope that is fine. 🖐👴 have a nice day

[@derpydude2739]

Interesting! 😊

[@MrDino1953]

@Rockfarmer - we would have continued exposing our ignorance. And now you have a little bit of specialist knowledge that you can impress people with at dinner parties.

[@paulmorgan1009]

It’s important and respectful to try and do your best to pronounce another language right. Particularly places like this and in the sense that he’s giving an educational talks and even risk advisories at times with these videos. It’s hard a lot of the time to pronounce even words in one’s native tongue for any number of reasons. He has a habit though of being sloppy or even pronouncing it right then wrong in the same video giving the impression he’s doing one takes and churning em out. There are a lot of cool people like this guy who do similar All be a different topic videos like this on KZbin and a number of them at least say “hey sorry if I mess this up it’s hard my b”. I wish he would at least just do that. This video is just one of a lot of examples of that. And I really like his stuff so I hope he does attempt to do better.

[@adriennefloreen]

It's nice how you showed clips of yourself checking it out in your orange jacket you wore the first time you showed your face on KZbin. In my opinion you should wear that bright jacket every time you go visit a volcano. So your subscribers can see you are there from a mile away and say hi!

[@Chacanger]

I went to this crater about 4 years ago, the lake was frozen and people walked on the lake. It's very photogenic too because of the array of colours.

[@marinafartify]

Thanks for the shout out!! Always enjoy your videos and looking forward to your expanding geological content!

[@royvdl2815]

How fitting, last week I stood on the ice in the crater and now i get this recommanded.

[@user-iu4se2ps7d]

Would love to visit Iceland someday, their nature is absolutely beautiful

[@cbremer83]

The only place I have seen scoria rock is on oil pads in North Dakota. It was the most common rock used for ground cover on the site/pad. Not sure why. It is a pain to walk and work on though. Big old ankle busters. I always wondered where it came from, but nobody knew the specific location. Just that it was from volcanos.

[@ZebaKnight]

I just saw a red volcanic crater in Chile (on the latest video in Snow and Curt's van tour of the middle and south American countries). I wondered what the composition of the volcanic rock in that singular crater is. I thought it might be oxidized iron, but now I bet it is scoria. I learn so much here!

[@DanielBerke]

I was thinking at the start of the video, "That looks like a cinder cone," glad to discover I was right!

[@wtglb]

[@felicityhoneycutt8570]

Ok who's the one wise guy that disliked this video?

[@peter5.056]

I'd like to request the topic, "what evidence (if any) exists in the geologic record, of cosmic ray events, such as the Miyake Events - such as the 774-775 carbon-14 spike? What other traces of cosmic events can be detected in Earth's geology?"

[@brandoncarstensen1637]

I got a interesting idea for a video. Look into geologic oddities called "Carolina Bays" most prominent in north/south Carolina. Large, shallow and oval shaped lakes all lined the same direction almost. South east side tends to have a higher sand bank than any of the other shores on them. Also noted bays have been found in Nebraska also and point towards Michigan, along with the ones on the east coast. Rather weird formations.. these are also found in Alaska as well.

This is breaking from yesterday The AVO from USGS has lowered the alert level from Orange to Yellow on both the Tanaga and Takawangha because of the rapid decrease of the earthquake swarm on both volcanoes.

[@flashgordon3715]

There are two holes in the ground that look just like that near Mammoth Mountain, California. Inyo craters.

[@johnandannastravels6258]

We enjoyed hiking around the ridge of this crater. Now I know how it formed.

[@sciencegeekgrandpa8]

Not an icelandic speaker here, but the letter that looks like a 'd' with a stroke through the top is called 'eth' (kind of like "the" backwards), and is a single letter for the sound we hear in "the" except it never occurs at the beginning of the word. So, geology wise, wouldn't it be correct to call this a micro-caldera, since it seems to be formed by the same mechanism--the evacuation of a magma chamber?

[@angelomelendez4828]

It is similar to Cerro Pasquí, near Irazu Volcano, Costa Rica

[@thegotlandisfarmer8774]

I would like to know about the story of Earthquake lake Montana

[@mar83161]

My parents in NW Wyoming felt it in 1959. My business partner's Dad in Whitehall MT was the first to get a Cat to the area and start working on the slide to try to get to the people in the campground.

[@robertfarr9186]

My first guess with the word “crater” that it was made by a small meteorite. Only humans would believe that they have to maintain a hole in the ground, and charge other humans to do it.

[@gaius_enceladus]

I wonder how deep the lake is?

[@noraleestone2859]

55 meters, or 185 feet deep..

[@ivanviehoff6025]

The correct spelling is Kerið. It's pronounced Kerith (ith similar to English with). If you can't use the special ð letter, you can write Keridh. Your automated speech generator also had a little problem with Fagradalsfjall. What would it make of Þingvellir, that very geologically interesting place? As you say, Kerið is geologically interesting because it formed differently from most other small craters with water in the bottom. But unless you are a real geology freak, it's just a crater with water in the bottom, and of rather moderate scenic interest in comparison to what else there is to see. I've been to Iceland many times, seen many scenically interesting craters with water in, and I certainly wouldn't pay even that modest 450 ISK to see Kerið. But I suppose it is included on many day trips out of Reykjavík because it is quick and easy to visit while you are on a Golden Circle (Geysir, Gullfoss, Þingvellir) day tour.

Wish you'd say the conversion would be into feet also. Not everyone watching cares to do the conversion in there head.

[@noraleestone2859]

He did do the conversion. The crater lake is 55 meters, or 185 feet deep, for example. He says that in the very beginning of the video. 😁😉
