You’ve seen the screenshots. Maybe it was on a late-night Reddit thread or a viral TikTok where a creator drops a digital warhead on their own hometown. It’s a morbidly fascinating sight: a colorful, expanding ring of fire and pressure waves stretching across a familiar Google Maps interface. Most people call it a google maps nuke simulator, but there is actually a specific name behind the tech that fuels these nightmares. It’s called NUKEMAP, and honestly, its creator, Alex Wellerstein, probably didn't realize how much of a cultural staple his project would become when he first launched it over a decade ago.
It feels wrong to call it a "game." Because it isn't one. There are no high scores or levels. Instead, you're met with the cold, hard reality of physics. It’s a tool that takes the abstract fear of the Cold War and pins it to your local grocery store or your childhood elementary school.
What is a google maps nuke simulator anyway?
Basically, these simulators are mashups. They take the Mapbox or Google Maps API—the same stuff that helps you find the nearest Starbucks—and overlay complex thermal and blast radius models on top of it. When people search for a google maps nuke simulator, they are usually looking for NUKEMAP. It’s the gold standard.
Wellerstein, a historian of science at the Stevens Institute of Technology, built it to help people visualize the scale of destruction. We talk about kilotons and megatons, but what does that actually mean? For most of us, those are just big numbers. But seeing a 100-kiloton blast wave cover your entire city? That’s different. That’s personal.

The way it works is deceptively simple. You pick a location. You pick a weapon—maybe a "Fat Man" like the one dropped on Nagasaki, or a modern Russian Topol. Then, you hit the "Detonate" button. The simulator calculates the fallout, the heat, and the pressure waves.
The science behind the scary circles
It isn't just random shapes. The math is based on declassified government data and the "Effects of Nuclear Weapons" by Samuel Glasstone and Philip J. Dolan. It’s a heavy book.
When you detonate a virtual bomb, you see several distinct layers. The innermost circle is the fireball. Anything inside that is basically vapor. Then you have the heavy blast damage zone, where concrete buildings are leveled. Further out, you get the thermal radiation radius. This is where you get third-degree burns.
The terrifying part? The "google maps nuke simulator" experience shows how much a modern weapon dwarfs the ones used in World War II. A Tsar Bomba—the largest nuke ever tested—would create a fireball so large it could swallow entire metropolitan areas. The heat would cause fires dozens of miles away.
Why we can't stop looking
There is a psychological term for this: morbid curiosity. But it's also about control. We live in a world where these things exist, tucked away in silos or on submarines. Using a google maps nuke simulator is a way to confront the unthinkable from the safety of a browser tab.
Some people use it for research. Emergency planners have actually used these models to understand what a "dirty bomb" or a localized strike might do to infrastructure. But for the average user, it's a sobering reality check. It turns the "unthinkable" into something visible.
Misconceptions about "Official" Google tools
Let's clear something up. Google does not have an official "Nuclear War" mode. You won't find a "Detonate" button in the standard Google Maps menu between "Satellite" and "Street View."
While these third-party tools use Google’s mapping data, they are independent projects. Google actually has a history of being pretty careful about how their mapping tech is used. They don't want to be the "Doom" company. They want to be the "Get you to your 2 PM meeting" company.
However, the integration of these simulators with high-resolution satellite imagery is what makes them so effective. Seeing your own roof under a "100% casualty" overlay is a lot different than looking at a paper map from the 1960s.
The technical limitations of your browser
Simulating a nuclear explosion is incredibly hard. These web-based tools are approximations. They don't account for every hill or valley that might block a blast wave. This is called the "shadow effect." In a real-world scenario, a mountain might protect a neighborhood from the worst of the heat. Most browser simulators assume a "perfectly flat" world for the sake of speed.
Also, fallout is a guess. Weather patterns change every second. The google maps nuke simulator usually lets you pick a wind direction, but it’s a static model. Real radioactive fallout is a chaotic, shifting cloud that depends on rain, altitude, and temperature inversions.

How to use these tools responsibly
If you’re going to dive into this, don't just click buttons until the screen turns red. Use it to learn. Look at the difference between an airburst and a ground burst.
- Airbursts are designed for maximum destruction of buildings over a wide area. They create more "pressure" damage.
- Ground bursts are for destroying underground bunkers. They create significantly more radioactive fallout because they suck up dirt and debris, turn it into radioactive ash, and spit it back into the sky.
Understanding this distinction helps you see past the Hollywood version of a nuclear explosion. It’s not just a big fire. It’s a complex, multi-stage environmental disaster.
Modern alternatives and variations
NUKEMAP is the king, but there are others. "Outrider" has a very slick, modern interface that focuses more on the human cost. It tells you how many people would be injured versus how many would die. It’s a bit more "polished," which somehow makes it even more unsettling.
Then there are the VR versions. Some developers have tried to create "Nuclear VR" experiences where you stand in a city while a blast occurs. Most of these have been pulled from mainstream stores because they are, frankly, traumatizing.
Actionable steps for the curious
If you want to explore this topic without spiraling into a pit of existential dread, here is how you should approach it.
First, start with historical context. Use the google maps nuke simulator to look at the Hiroshima blast (15 kilotons). Look at how small it is compared to modern cities. It’s a stark reminder of how far weapon technology has come.
Second, look at the fallout patterns. Change the wind direction. See how a blast in one city can poison the water and soil of a city three states away. This is the "global" part of nuclear war that people often forget.
Third, read the "FAQ" sections on these sites. Alex Wellerstein’s blog, Restricted Data, is a goldmine of information. He explains the math. He explains the history. He explains why he built the thing in the first place.
Finally, use this knowledge to engage with real-world policy. The point of a simulator isn't to scare you into paralysis. It’s to make you an informed citizen. When you hear politicians talk about "tactical" nuclear weapons, you can go to the simulator and see that there is really no such thing as a "small" nuclear war. Every "tactical" strike still involves thousands of lives and long-term ecological damage.
Seeing the "circles of death" on a familiar map changes your perspective. It moves the conversation from "if" to "what if," and hopefully, it makes the prospect of these weapons being used feel as unacceptable as it truly is.
