Hawaii’s surprise volcanic eruption: Lessons from Kilauea 2018

In 2018, Hawaii's most active volcano took scientists by surprise. Lava started spewing out not from the summit, but 50km away on the lower slopes of the volcano. This unexpected eruption destroyed farmland, roads and over 700 homes. Since then, volcanologists have been piecing together the events that triggered it.
Using GPS trackers, high-speed cameras, chemical analysis and more, researchers have learnt what happens when volcanic craters collapse and how magma can move not just vertically but horizontally underneath a volcano. These insights help us to understand other similar volcanoes in Iceland, Italy and La Reunion. The hope is that next time Kilauea or one of these other volcanoes erupts, we will be better prepared.

The earthquake scene was fantastic.

[@hebneh]

While this eruption was surprising and dramatic in where it began and how much lava it produced, the concept of flank eruptions on Kilauea (and Mauna Loa) is very well known and not a surprise at all. They have happened repeatedly in known history - and in fact that's why the term "rift zone" exists. It refers to a long skinny area in which eruptions like this have occurred in the past and will happen again in the future, when lava will literally just start coming up out of a new crack in the ground.

Excellent video, I had no idea that things like this exist.

[@joelugalpez4894]

Well Oskar, make sure you won't ever forget. The reason of eruptions are due to the direct connectivity of every volcano to the Earth’s core which burn constantly at about 6,000 Celsius. The earth is a complicated creature even for scientists. Luis Galicia

Very nicely done video. Good schematics and not as lurid as in many TV documentations. Thanks!

[@ConservativeMan59]

Very well done video. It made the 2018 event much easier to understand. Again, great job y’all!!

[@64482]

Pronunciation aside, this is a great video that clearly illustrates the volcanology involved in this series of events in a way I hadn't seen before. Good selection of raw footage, although at one point an empty Pu'u'o'o crater is misidentified as Kilauea's summit caldera; they did both collapse, though.

[@cherylgriffith2682]

Something like this happen in 1955. The trajectory of the fissures was little bit different but basically in the same area. In 1960 k a p a h o Village got destroyed and it's even further away. I would be interested in what happened before 1955 like 1924

[@64482]

1924 was entirely different and took place at the summit. The lava lake at Halema'uma'u crater (where Pele and her family of fire gods live) drained, triggering earthquakes and collapse events that blocked steam from being able to escape the magma plumbing system. As groundwater flowed into the now-drained-but-still-super-hot lava conduit, it flashed to steam, pressurizing quickly. The explosive eruptions (as opposed the the effusive eruptions in 2018) that followed lasted for two and a half weeks as the cycle of collapse, plug, pressure, explosion repeated dozens of times. The eruption columns stretched over five miles into the sky, boulders the size of cars were thrown into the air, and to this day the explosions remain the most powerful on Kilauea since the early 1800s.

[@cherylgriffith2682]

@@64482 thank you so much for the education. This volcano is fascinating. I do wonder about activity in the East Rift Zone before 1955

[@ernestopreciado4895]

1:05 How is no one mentioning how he collected lava with a bucket????

[@hebneh]

He collected the lava on a shovel, and then he put the molten rock into a bucket with water it it, to cool off its surface. This is done at Hawaiian eruptions regularly.

I guess I was lucky I did not buy land while I was there several months before this happened...

[@amandathurston2720]

So with this one going quiet in 2021, and the new ones popping up in Iceland...wonder if that’s connected.

[@baddgeeksquad]

Nope, Iceland is from a major rifting event along the reykjanes peninsula, which last happened in that area back in the 1200s, there was also a 9 year long rifting event at krafla which is another volcano in Iceland, but it’s in Northern Iceland, and it lasted from 1975 to 1984, but the reykjanes peninsula rifting events almost always past for either decades or for over a century, the last rifting event was known as the reykjanes fires and had many eruptions. Since the period started, there has been 1 volcanic earthquake swarm at the mainly submarine eldey volcano, 10 magma intrusions and 4 eruptions at the reykjanes volcano, which happened in December 2023, January 2024, February 2024, and the march 2024 eruption ended a few days ago, then at the fagradalsfjall volcano, there has been 4 magma intrusions and 3 eruptions,1 in 2021, 1 in 2022, and 1 in 2023, the krysuvik volcano has had 3 volcanic earthquake swarms and 1 magma intrusion, and the brennisteinsfjöll volcano has had 1 volcanic earthquake swarm. And the timing of the Kilauea eruption ending was just coincidencidentally well timed near the start of an Iceland eruption, since 2021, I’m pretty sure there was an eruption that lasted nearly a year, and then 3 eruptions in 2023. This would easily show that it’s not connected, and basically barely any volcanoes are connected

[@Amitdas-gk2it]

TY 😊

[@polygon-viewer]

It's now believed that the 50" of rain in one day just before that eruption increased pore pressure in the rock, allowing magma to fracture it easier.

After they have been studying this for how long ?????

[@RoughAndWretchedRAW]

What 2018 taught me was how tyrannical and commercial the Hawaiian government had become. They had a massive chance for tourists and the public to witness the wonders of nature but if you weren't a scientist and didn't have the money to pay a tourism company you were banned from getting anywhere near it. There is as much happening in Iceland right now and all people are allowed to witness it free of charge. Hawaii Makes a whack of excuses for their bans in a nation that is supposed to represent freedom, While Iceland skips the excuses and just allows freedom by default as it should be. The US went from being a free country where capitalism thrives for the benefit of the people they serve to a nation enslaved by corporations and the corporate good alone.

[@havingicecream]

Because they fucking _rock_ ?

Because nobody knew that this could happen? Whether you're aware of it or not, you're constantly managing risks in life, even if you don't live on a volcanic island.

[@robertbrewer2190]

@@unvergebeneid It was basically a land swindle. It is relatively cheap land on an island that is being bought up by the wealthy. It was a known eruption zone and the county politicians approved of it anyway. Lots that are still steaming are for sale. One fellow conducts tours on his lava lot! In Florida it would be under water!
