Sonic boom from a stationary object! Awesome.

I wish I knew what a "smokin' toledo" was.

I love that you can see the shockwave hit the clouds.

Oh man. The island moved again.

Saw this yesterday, and watching it again just now I still said "Wow!" out loud.

Fuck people who can't even manage to swear properly at things that 100% deserve some fucking swearing.

OH MY GOD THE HORIZON DOES NOT BELONG IN THE MIDDLE OF THE FRAME

I couldn't finish watching. I was trying SO HARD to use the power of my mind to tilt the camera up just a little bit. Just a LITTLE BIT.

I fucking love swearing, but I appreciate folks who have the temerity to say something silly like "gee willikers" or "holy smoking toledos". More memorable imo.

Can a pyroclastic flow move over water? I found myself wondering whether that cargo ship over there was at risk of being sunk by all this.

Those cargo boats were a lot farther inshore than I would be if passing under the shadow of a volcano that is erupting.

The flow will sink but they're probably in some danger from flingin' ass boulders.

komara, I am assuming that the camera was on a fixed platform, not hand held, thus the lack of panning up as the cloud grew.

As they're known in geological circles.

whenever I see stuff like this I always imagine all the volcano gods high fiving one another in a hot smoky bar and spilling their pints of magma ale everywhere

That was really cool. I'd love to experience something like that IRL. At a safe distance, of course.
posted by InsertNiftyNameHere at 5:48 PM on September 7, 2014


That is a great clip.

I watched the part between seeing the eruption and the arrival of the sound over and over again but could not see any sign of a shock wave in the water traveling toward the boat, which surprised me.

Also, what I thought I saw in the air above the volcano was a wave of condensation in the wake of the shock wave due to decompression.

Um, this is clearly from Skyrim, and it's backwards. It's a dude using the dragon shout sodelot gnikoms yloh to force an ash giant back into its underground lair.

Yes. This video shows just that starting at 0:33. The footage comes from the Soufriere Hills volcano on Montserrat which erupted several times in the late 1990's.

Actually, here is a better video of the pyroclastic flow on Montserrat moving over the water. It left behind a large fan shaped deposit of debris--growing the island out as a result. The over water flow starts at 4:53.

I counted between the explosion and the sound arriving and I gotta say that's closer than I would want to sail to an erupting volcano.

Oh...and 8 years ago I went to Papua New Guinea to catch a research ship and spent about a month working just off shore. The day before I arrived, some of my colleagues who arrived before me hiked up into this very volcano one morning. Later that same day, it erupted! They were very very lucky. And we did see ash deposits and lots of pumice floating on the sea surface while we worked just off shore.

I like that too, if it's what they normally do. In this case, it's pretty clear they want to swear, but catch themselves for whatever reason and just replace it with some weak shit they come up with on the fucking spot.

The video of the dude rappelling into a live volcano would suit this thread. Close enough to the ferociously boiling magma that bits of it were landing around him. Insanity.

that is so cool. does anyone know the mechanics of the white cloud that appears at 00:13 and disappears at 00:14? i'm assuming its water vapor but it seems to deform sooner than it forms. what would cause that? is it a mechanism of the sonic boom? similar to the vapor clouds that form around jet planes? it appears to expand before the initial ash cloud and then the energy seems to be subsumed by the ash and then get transmitted a few hundred feet away into the actual sonic boom.

"Holy, Toledo!" is a swear replacement. He paused to consider "smoking" since that is what the volcano is doing.

Phil Plait talked a bit about this yesterday--he said that the clouds formed were from the air compression of the eruption.

He also points to this page from NASA's Earth Observatory, which offers before-and-after photos of the island. (The first photo is from April, the second is September.)

The badassness of volcanoes was driven home for me on the way to Mt. St. Helens, when I started to see the trees broken in half and realized we had about 45 more minutes of driving to do.

the white cloud that appears at 00:13

It's a blast wave.
posted by Johnny Wallflower at 7:35 PM on September 7, 2014


i understand the blast wave but don't get what causes it to subsume so quickly. does the subsequent ash cloud exploding just steal al the energy?
posted by Conrad-Casserole at 7:38 PM on September 7, 2014


Look closely at the ridge of the volcano left of where the explosion/venting occurs, from 0:07 to 0:13 of the video. It may just be video artifacts from the motion of the boat, but it sure looks like there are some crazy earth movements happening up there before it erupts.

stbalbach: ""Holy, Toledo!" is a swear replacement. He paused to consider "smoking" since that is what the volcano is doing."

It sounds to me like he's starting to say "Holy shit!", but stops at the "s" in shit, and comes up with "smoking Toledo".

Are you talking about the blast wave cloud? As I understand it, when the shock spreads through the air, it compresses it, but right behind the wave of compression there's a wave of decompression. Just like how waves in water move up and down. The decompressed air can't hold as much water vapor, so the water suddenly condenses out. Same way clouds form, just much faster. It disappears quickly as the air pressure returns to normal.

"Flingin' ass boulders" is my new euphemism for taking a shit.

"is it a mechanism of the sonic boom?"

You don't even need a sonic boom to cause that phenomena - water vapor forming and quickly disappearing. I was working very near the airport and you see the same thing, when weather conditions are right, trailing the flaps of larger commercial planes as they are landing.
From scientificamerican: Because aircraft wings generate both low-pressure regions (because of lift) and amplified low-pressure disturbances, large low-pressure regions exist near the aircraft, especially under sonic flight conditions. The lowered pressure condenses the water in the air, creating a vapor cloud.
Also I grew up in Washington State and no freaking way could get me that near to a smoking volcano [unless it's a shield volcano].

Now, I will say I'm a fan of the well-placed epithet, to wit, in two recent films an apposite, standalone "Fuck!" (All is Lost, and Dallas Buyers Club). But if you're taking a video that you have a sense you are going to YouTube, potentially even shown in classrooms, maybe going with TV/newspaper language is best.
