👀 The 7.8 magnitude earthquake that struck Mindanao caused parts of the seabed to rise by as much as 2 metres and the coastline has reportedly moved out by around 200 metres.

The sudden uplift has exposed coral reefs, seagrass and marine habitats, leaving sea life stranded and causing damage to the underwater ecosystem. Officials found exposed coral and dead marine animals along affected areas.

It’s incredible to think about the force needed to physically lift the seabed out of the ocean like this.

🔥 Why did some homes survive the 2025 LA County fires while others didn't?

In the latest episode of the Disaster Discussions Podcast, IBHS researcher Dr. Xareni Sanchez Monroy breaks down findings from The 2025 LA Conflagrations report and explains how factors like structure spacing, wind conditions, and everyday combustible items influenced home survival.

INSANE GROUND SCOURING! KOUTS, IN!
Insane ground scouring was documented from southwest of Kouts, Indiana, through the north side of Kouts and toward Wanatah, Indiana, likely caused by intense sub-vortices within a violent tornado. The scouring stretched for miles, showing just how powerful this tornado was.

This was a violent, destructive tornado with extreme ground-level damage.

🔥 After a fire is extinguished, the real danger may just be beginning.

I just dropped a new YouTube Short — "What's in your home after a fire?" — and it covers something that doesn't get nearly enough attention: what's actually left behind in a property after a fire, and whether anyone is making sure it's safe before families move back in.

Here's what we know:

⚠️ Lead, asbestos, heavy metals, VOCs, and SVOCs don't disappear when the flames go out. They can settle into walls, floors, dust, and air.

⚠️ There are no universal, health-based standards for testing residential properties after fire events. That means families, including children, can return to homes that have never been properly assessed.

⚠️ Children are especially vulnerable. Their developing systems are much more vulnerable to chemical exposures than adults, and contamination at levels considered "acceptable" for adults can cause lasting harm to kids.

This isn't a fringe issue. It affects wildfire survivors, structure fire victims, and entire communities. The evidence is clear even when the policy hasn't caught up.

The conversation is starting to change. Legislators, public health advocates, and communities are beginning to demand better — and they should.

Watch the short. Share it with someone who needs to hear it. And ask the question: who's protecting families when the smoke clears? and why aren't there health-based standards?

A paper on AI, written by humans. Worth reading:

[Nav Toor @heynavtoor]

You have noticed it. ChatGPT feels dumber than it used to. Your prompts that worked six months ago produce worse results now. The writing sounds flatter. The ideas sound safer. The internet itself feels like it is shrinking. Every article reads the same. Every email sounds the same. Every answer sounds like it was written by the same voice.

You thought it was you. It is not you.

Researchers at Oxford and Cambridge published a paper in Nature proving what is happening. They call it Model Collapse.

Here is the mechanism in one sentence. AI trained on AI-generated data gets dumber every generation until it forgets what real human data looked like.

The internet is filling with AI-generated content. Blog posts. Articles. Reviews. Comments. Social media. AI companies scrape the internet to train the next generation of models. Which means the next generation of AI is being trained on the output of the current generation.

Each cycle loses information. Not randomly. It loses the rarest, most unusual, most creative parts first. The researchers call these the "tails of the distribution." The weird ideas. The unexpected perspectives. The things that made the internet feel human. Those disappear first.

What remains is the average. The safe. The expected. The bland.

Then the next generation trains on that. And loses more. And the next generation trains on that. And loses more. The researchers proved this is not a slow decline. Major degradation happens within just a few iterations. Even when some of the original human data is preserved.

They tested it on large language models. On image generators. On statistical models. The pattern was the same every time. The output converges toward a narrow, flattened version of reality that looks nothing like the original data.

The lead researcher put it plainly. "Large language models are like fire. A useful tool. But one that pollutes the environment."

The pollution is invisible. You cannot see which sentence on the internet was written by a human and which was written by AI. Neither can the AI that is about to train on it. And once the tails are gone, they do not come back. The damage is irreversible.

This is not a prediction anymore. It is a diagnosis.

The internet you grew up on was built by humans writing things no algorithm would have written. Strange, personal, imperfect, alive. That internet is being diluted. One generation of AI at a time. And the models trained on what remains are learning a smaller and smaller version of the world.

Model Collapse is not a technical problem. It is a cultural one. The thing that made the internet worth reading is the thing that disappears first.
