The Maldives cave diving tragedy, May 2026

[Bill Ryan]

Dear Friends, here's the first new thread in this new section on Adventure Sports, Scuba diving definitely being in that category.

One of the challenges in any kind of adventure sport is that one is deliberately putting oneself in some kind of potential danger (whether mild or extreme), and things can sometimes go wrong, with skill, courage and high competence being needed to salvage a situation that has suddenly gone bad.

However, the seeking of reward in terms of sheer adventurous experience (and those of sharing that experience with close friends) are deeply hardwired into the human condition. That's why people do these things.

Last week, 5 Italian divers, with significant experience, all died when exploring a deep undersea cave in the coral reefs of the Maldives. Soon after, a Maldivian military rescue diver also died once it was known they were missing.

In the world of diving, this has become a major incident and there have been dozens of videos and articles, including on mainstream media, covering the tragedy, one which in the diving community is pretty rare.

Some of you may be aware of the story already, but for anyone interested who's not heard about this here's a 4-minute Australia news report that covers what happened as a brief but accurate summary:

The same video here:





I've done some diving myself, qualified and experienced only at a basic level. But I do know something about this. One of the things about adventure sports is that there are crossovers between them all, and there are quite some similarities between diving and high altitude mountaineering.

There's been extensive discussion about this online in the specialized diving community websites and forums. including in many of the YT and media comments sections.

What's being shared is insight into the mistakes that were made. And this is one of the crossovers... pushing the boundaries into risky territory where if something goes wrong there's diminishing chance of a safe outcome.

This is a little technical for anyone reading this who knows little about the accident or about diving in general. But here's what almost everyone agrees happened:

• They went too deep. (50+ meters). That doesn't seem like much, but I've never been deeper than 20 meters myself. (I wasn't trained or qualified to do so.)

• Diving to 50+ meters can be done safely by those with the right training, experience, and equipment, but the deeper one goes the more redundancy is needed in one's equipment and plan for the dive. The "Rule of Thirds" should never be broken: 1/3 of one's air for the dive, 1/3 for the return, and 1/3 in reserve for any possible emergency.

• Not only did they go too deep for the equipment they had (just one tank of regular compressed air each), they then ventured into the cave. At that point, every hazard is magnified as many more bad things can happen. One of the major rules of cave diving is that you lay out a guide rope, with "which-way" direction tags on it that can be felt with one's fingers even if one cannot see, so that one can always find one's way back to the cave entrance. This team not only had no redundancy in their air supply, they had no guide rope either.

After the Maldivian rescue diver also died, the most experienced cave rescue team in the world flew in from Finland to help, using highly specialized equipment.

One of the divers' bodies had already been found, near the cave entrance but still very deep. The Finnish rescue team located the other bodies four deep in the cave. At the time of this post, it's been reported that two of those bodies have been retrieved. What the Finnish rescue team did was a testimony to their ability and experience, in an extremely dangerous environment. This was no easy or simple thing.

The divers who died will all have had personal dive computers, like an athletics smart watch and which looks like this:



Reading the memory in their dive computers will help explain exactly what happened, and when, and from that it can be extrapolated what mistakes were made. (A dive computer has the specific purpose to tell the diver what to do, what NOT to do, and (importantly) when.

And finally, their tanks can be measured to see if they were empty or not. If they're empty, it means they simply ran out of air and drowned, having been lost or somehow trapped in the cave for way too long .

If they're NOT completely empty, it implies that they were affected by nitrogen narcosis, a technical thing that can quite easily happen when diving too deep which results in impaired judgment similar to being very drunk. When that kicks in, a diver has zero chance of making good decisions and is solely dependent on unaffected fellow divers to help them if they can.

Finally, it's reported that one of the divers was wearing a Go-Pro camera, which can also be played back to see what happened, when, and why.

None of these findings have been reported yet, so working to understand precisely what happened to them all is still ongoing.

Do we have any experienced divers in the Avalon community?

[Bill Ryan]

For those interested in more of the nuances of the incident — without getting into the technicalities of diving itself and exactly what might have gone wrong — here's an excellent new 20 minute video deconstructing the human element of the tragedy and what some of the important context of the fatal dive might have been.

It's all speculation, and while Nick van der Leek (the host of this channel, which usually has a 'True Crime' focus) sometimes gets things wrong and goes too far with his guesswork, here I think he might have offered some helpful insights. (Van der Leek has an adventure sports background himself, so he's not unqualified to offer cautious opinions.)

The factor that makes this video different from almost every other report about this on the net — and there are scores of them, easily found — is that it's not just technical divers holding forth about safety margins. (Safety margins were definitely breached, but that might not be the real moral of the story.)

A footnote:

If you read the comments (many from highly experienced divers, which are very interesting and technically well-informed), there's reference to a sixth member of the dive party, also a University of Genoa student, who was on the boat with the others but changed her mind at the last minute and chose not to go.

She's yet to make any public statement, but what she knows and understands about their dive plan is sure to be very helpful to the official investigation about what the heck really happened and why.

#BREAKING Italian newspaper
@repubblica
has reported a new hypothesis surrounding the Vaavu Atoll #CaveDive tragedy, suggesting the divers may have been caught in a powerful “Venturi effect” current inside the cave system.

According to the report, pressure differences created by currents moving through narrow cave passages may have pulled the group deeper into the third chamber, causing disorientation, reduced visibility and eventual air depletion. The theory is now among several being examined by Italian and Maldivian investigators following the recovery of all bodies by Finnish cave divers. #VenturiEffect #Maldives

The divers who came to retrieve the bodies of the Italian divers are among the most experienced cave divers in the world.

Two of them were involved in the infamous Plura Cave Incident.

Patrik Grönqvist survived the Plura tragedy and later refused to leave his friend’s body inside the cave system.

He returned into the cave with a small group of fellow divers on an extremely dangerous recovery mission.

One of the divers who joined him was Sami Paakkarinen and he was also part of the Maldives recovery mission.

Since I experience profound claustrophobia from confined spaces, there is no way I would even attempt this kind of activity, same with cave exploration, I have read of unfortunate souls being trapped in very narrow niches in some of these complex subterranean caves - it gives me the creeps, interesting how we all have different ideas about 'excitement' & what is a valuable use of our courage...I feel nothing but sympathy for these people, but really, why?

Patrik and Sami have been hailed as heroes (once again) for their exceptional courage, skill and professionalism.

They both look like unsmiling superhero badasses, and surely are. But many won't know that the third member of the DAN rescue team is a young woman, Jenni Westerlund, equally brave and skilled and every bit as badass as the two men. Heroism comes in many shapes and sizes.

Translated from Italian
The most powerful news from this tragedy isn’t just the recovery of the five Italians who died in the Maldives.

It’s another.

The Finnish cave divers who faced the darkness of the cave… asked not to be paid.

Take a moment to think about that.

They entered one of the most dangerous places in the world.
They risked their lives amid currents, depths, and absolute darkness.
They saw up close what no one would ever want to see.

And when it was all over, they didn’t ask for money.

Nothing.

In an era where many would do anything for visibility, they chose silence.
In a world where almost everything has a price, they showed that there are still people who act only out of humanity.

Sami Paakkarinen.
Jenni Westerlund.
Patrik Grönqvist.

Three people who are reminding us what it means to have a conscience, a heart, a soul.

Because bringing those five Italians home wasn’t just any job.

It was a human mission.

It was allowing shattered families to say goodbye.
It was giving peace to those left hanging between hope and despair.
It was turning an infinite void into a possible final farewell.

And certain things aren’t done for money.

They’re done because deep down, you feel it’s the right thing.

Today we live surrounded by people who shout, flaunt, demand applause for everything.

Then people like this come along.

People who risk everything… and want nothing.

And so perhaps the only right reaction is this:

to stay silent.

And say thank you.

Thank you, Sami.
Thank you, Jenni.
Thank you, Patrik.

Because you’ve reminded us all that true humanity still exists. 🌊❤️

Translated from Italian
DAN Europe, the Finnish divers' company that recovered the bodies of the deceased divers in the Maldives, claims it is very likely that the five Italians took the wrong tunnel in the Devana Kandu cave, mistaking it for the corridor that would have led them back to the entrance, and thus ended up in a dead end, where they were later found: "Given that they had a very limited air supply, they probably didn't have time to make numerous attempts to find the correct exit." One of the rescuers said the bodies were in a completely dark hole: "They were scattered here and there in an area of two or three meters. I've done many operations, but this one was very sad. I'll never forget it." There are no deposited maps of the cave in question: "None of us knew it well"

Yes. I'm pretty sure this is what happened.



Here's a better diagram, the clearest that I've seen:



As with many accidents of all kinds, the cause was a multiple pile-up of factors.

It's agreed by the entire professional diving community that they were cutting it very fine, to the degree of taking a considerable risk with the limit of their air. They had no room for error.

If they'd found the way out correctly after being in the second chamber for a minute or two, they'd have got away with the risks they took.

But they didn't lay a guideline to follow back to the entrance, they made a fatal wrong turn in the dark, they had no map of the cave (no good map existed), they got confused, they probably panicked, and one by one they all drowned in a small tight group holding on to one another.

It's pretty awful to think about.

~~~

Some personal reflection. In all adventure sports, two things can happen as one gets older and does more and more.

1. Experience breeds confidence, and one gradually becomes less cautious.
2. Experience simply makes one more cautious.

I'm 100% definitely in the #2 camp. That's why I'm still alive after all these years.

[Ravenlocke]

Yes I am also in the 2 category, caution, caution, caution. Especially undertaking something like this, not just a dive but a deep dive, in the dark, no backup tanks, not explored yet I think.

You just don’t know what awaits, but later it might be, “Hindsight is a beautiful thing”, except it may be too late to realize. Very tragic in this case.

Translated from French
🇲🇻🇮🇹 FLASH | Finnish divers who recovered the bodies believe they have identified what caused the death of the five Italians trapped in an underwater cave in the Maldives.

According to initial findings, the experienced group would have mistakenly taken the wrong tunnel during the ascent after being misled by a "sand wall illusion" in the darkness of the cave.

Rescue teams found the bodies in a dead-end corridor located at a depth of about 50 meters.

Experts estimate that with their standard 12-liter bottles, the divers had only a few minutes of air supply at that depth. In a state of panic and disorientation, they would have quickly consumed all their air.

Investigators are now analyzing the GoPro footage and recovered equipment to precisely understand what happened. (La Repubblica)

Like many I've only ever done recreational diving, which was all I ever wanted and - oh boy! - some of the experiences I've had in Turkey with its crystal-clear Mediterranean water and sea turtles were unforgettable and more than enough adventure for me.

I remember having a discussion with two of my instructors back in the UK about the hazards of cave and wreck diving. One possibility, particularly when exploring old submerged ships is that one can disturb the silt on the bottom and set off a snowstorm which can cause the visibility to become zero within seconds to the extent that you can't even see the bubbles coming from your regulator / breathing apparatus, and that most tragedies occur when no guide rope has been used. It can happen in confined caves too, such that that the silt cloud may not disperse quickly because there’s little current to clear it.

Could this have happened? That once the sediment is disturbed underwater, visibility collapses rapidly, and the sandbank in front of you simply looks like a solid wall, creating a dangerous illusion in the darkness (aka "silt-out") whereby divers become completely disoriented.

Yes. Here's a 30-second video (recorded by earlier divers a while back) of the exact same cave.

https://avalonlibrary.net/Bill/Insid...dives_cave.mp4



Two important things are evident:

1. They have dual tanks (not just one).
2. Watch their finning technique. In open water, one naturally fins 'vertically' by moving one's legs 'up and down'. But in a confined space with a silty floor, that's very likely to disturb the sediment. So part of ocean cave dive training is to move one's legs and fins as if one's doing breaststroke in a swimming pool.

A photo shared by a family member of Sergeant Mahdhee.

Beyond any doubt, Mahdhee was everything described in this photo and more. He was a courageous hero who descended into that cave fully aware of the risks involved, in an attempt to retrieve the bodies of four Italian divers so their families could grieve and lay their loved ones to rest.

We must never forget Mahdhee or the sacrifice he made in service. If it were up to me, I would even rename the cave in his honor.

But honoring him with words alone will not do justice to his sacrifice!

The most important thing now is to carefully investigate what led to this tragic incident, learn every possible lesson from it, and ensure that such a tragedy never happens again. We cannot afford to lose another life the same way.

If we fail to learn from this incident, improve the safety of future divers, and fix the systemic failures that contributed to this tragedy, then his sacrifice would have been in vain.

I also remember instructors telling me that some cave systems in the UK are so tight and confined that divers sometimes have to remove their tank and push it through ahead of them in order to squeeze through narrow sections.

That really stayed with me because it underlined just how unforgiving cave diving can be compared with ordinary recreational diving — especially if visibility is suddenly lost or a diver becomes disoriented in a confined space.

Personally, I struggle to understand the appeal of that kind of diving; I think I would find it more spooky, if not downright terrifying, than enjoyable. But each to their own, I guess.
