Can be active or dormant!

Bonus: tell me where you're from, and if that influenced the imagery of a volcano for you

Record-breaking Tonga volcano disrupted satellite signals in space | Space

The January 2022 Hunga Tonga-Hunga Ha'apai eruption continues to astound.

An underwater volcanic eruption last year was powerful enough to generate plasma bubbles that disrupted radio communications in outer space, a new study finds.

The new results could lead to ways to avoid satellite and GPS disruptions on Earth, and to learn more about volcanoes on alien worlds, scientists added.

In January 2022, the Hunga Tonga-Hunga Ha'apai submarine volcano — a large, cone-shaped mountain located near the 169 islands of the Kingdom of Tonga in the South Pacific — erupted with a violent explosion. The outburst generated the highest-ever recorded volcanic plume, one reaching 35 miles (57 kilometers) tall, and triggered tsunamis as far away as the Caribbean. All in all, the eruption was the most powerful natural explosion in more than a century...

Hello!

Today I learned that in 79 CE, when Mt. Vesuvius erupted, it destroyed two cities. The city of Pompeii, and the city of Hurculaneum.

The catastrophies that happened at both of these cities were caused by pyroclastic density currents (also know as PDCs or Pyroclastic flows). These were large plumes of hot, dense ash and debris from the explosive eruption of Vesuvius. (AKA not Lahars)

In Pompeii, these PDCs were much cooler than the ones at Hurculaneum, and so the people were buried in ash and ultimately died of suffocation and not at the hands of temperature. The people buried left voids in the solidified ash filled with bones and sometimes clothing. Someone eventually got the bright idea to dump Plaster of Paris into these voids, and that's where we get the creepy and tragic statues of the people of Pompeii.

In Hurculaneum, the town was victim to whats called pyroclastic surges (a less dense, hotter version of a flow). They were extremely hot. The temperature was hot enough to kill anyone hit by it nearly instantly. It hit most of the town and the rest was covered by a lahar (volcanic mud/debris flow). We know this because the bones found in Pompeii were mostly intact and non-discolored. The bones in Hurculaneum, however were extremely discolored and there were no clothing remnants. Archaeologists later found that this kind of discoloration of bone only happens when they're exposed to extreme temperatures. (Teacher didn't cite the source for this one, cursory looks say this might be disproven in the past decade. He's usually pretty up-to-date though.)

Notice that there is no space between the surrounding "dirt" and the skeletons. The "dirt" here is volcanic product.

I highly recommend giving this article a read if you're interested in learning more about what happened in Hurculaneum. :)

Volcanology is a fascinating science !

I love vulcanos so much!!!!!!!!!!!!!!!!!! I could see pictures and watch videos of vulcanos and about vulcanos and see vulcanos in person and research about them and talk about vulcanos and igneous rocks for the rest of my life and be happy. Like actually they're so pretty and eruptions are so pretty and incredible and and and I'm in love (with the vulcanoes) also like vulcanic ash is so fun and cool and toxic I love it??? Can I get married to a vulcano is that a thing???? And eruptions also make lightning and thunder too and it's Awesome???????

For real if I was on a date with someone on a vulcano, I would straight up ignore them and pay all my attention to the vulcano, they're so good (the vulcanoes). Like, when I die, I want my body to be thrown in a vulcano, there no better final resting place. And Honestly? I was born in the wrong generation, I should've been born like, 640,000 years ago to see yellowstone erupting.

I have to visit a vulcano someday, I'll explode if don't I think

It's finally here! The Volgaynoes leftover sale will launch on February 13th at 8 pm GMT!!! 🌈🗻

This leftover sale is perfect for all of you who missed the Kickstarer crowdfunding or if you're one of our backers who loved your Volgaynoes so much you want more! This will be their one last run and they won't be available for purchase after this one last sale, so make sure to plan ahead if you were thinking of getting them.

Mark your calendars and set the alarms because we have an extremely low stock of some items, so make sure you don't miss them.

“Volgaynoes” is a science-art collaboration between us, Palaeoiris, and volcanologist and artist @alias_in_ink (Instagram) that shows off the beauty and diversity of volcanism on our planet, while simultaneously celebrating the diversity of humans too.

Our myriad magmatic creations illustrate the beauty and majesty of volcanic processes across the world in a series of colours that champion members of the queer population.

Our mash-up of science meets art shows the message: we want members of our Earth Science community to be visible and proud. They are also meant for allies to display, show their alliance, and help create welcoming environments for queer people. It's not easy being so often-prosecuted minority and so it's our hope to help you communicate your love for LGBTQ+ people and volcanology in one.

Adventures of Katia and Maurice Krafft, French vulcanologists. It’s a great blend of love, science and humour. This could be called summer vacation in extremely hostile environment. A portrait with many sides and stunning pictures.

Mauna Loa the largest shield volcano in the world erupted the other day- the first time since 1884. Yesterday it formed fissures on it's northern side. It is alarming for the fact that it is a precursor to other volcanoes on the Ring of Fire, (Rainier, Hood, St. Helens, Shasta, including Yellowstone.)

A few of these volcanoes are in the process of a slow eruption. (in some cases like for Yellowstone its a 20+ year process!)

Mauna Loa is a sight to behold. It created Hawaii after all.

Toba super-eruption unveils new insights into early human migration.

Modern humans dispersed from Africa multiple times, but the event that led to global expansion occurred less than 100,000 years ago. Some researchers hypothesize that dispersals were restricted to “green corridors” formed during humid intervals when food was abundant and human populations expanded in lockstep with their environments. But a new study in Nature, including ASU researchers Curtis…
