From SRP author Taylen Carver:
Seventy-four thousand years ago, the world didn’t end—but it sure gave it a shot. On the Indonesian island of Sumatra, the Toba supervolcano erupted in a cataclysm so enormous it makes every cinematic volcano disaster look laughable. Pompeii? Amateur hour. Dante’s Peak? A warm-up act. Even Mount Doom from The Lord of the Rings wouldn’t have survived Toba’s apocalyptic flex. This was the most massive volcanic eruption in the last 2.5 million years, a planetary event on a scale so vast it would be like Yellowstone’s biggest eruptions on steroids.
Toba spewed over 2,800 cubic kilometers of debris into the atmosphere, creating an enormous caldera that now cradles Lake Toba. It wasn’t just one of history’s most violent geological events—it reshaped the course of humanity. For years, scientists thought it nearly wiped us out entirely. But as new research shows, the truth is more complicated, and in some ways, far more intriguing.
A Blast That Rocked the World
When Toba erupted, its ash spread far and wide, blanketing parts of South Asia and choking skies from the Arabian Peninsula to the Himalayas. Sulfur particles billowed into the stratosphere, reflecting sunlight and plunging the planet into a volcanic winter. Some areas dried out; others became deluged with relentless rain. Temperatures dropped drastically, plants and animals died in droves, and ecosystems teetered on collapse.
It’s easy to imagine Toba as a harbinger of doom. After all, when volcanoes pop off in movies and TV shows, the message is usually clear: run, scream, and wait for fiery death. Remember the panicked chaos of Dante’s Peak? The lava-spewing carnage of Volcano? Or the raw power of Mount Doom in The Lord of the Rings? Those disasters are tiny flickers compared to Toba’s eruption. Toba didn’t just wipe out a town or two—it sent shockwaves around the globe, with consequences that lasted for centuries.
Survival and Innovation
For years, scientists believed that the Toba eruption caused a “genetic bottleneck,” nearly wiping out humanity and leaving only a few thousand survivors in Africa. But new evidence is flipping that theory on its head. While Toba was undoubtedly devastating, recent studies suggest its effects weren’t as uniform—or as apocalyptic—as previously thought.
Instead of wiping us out, Toba challenged our ancestors to adapt. In Ethiopia, archaeological digs have uncovered stone projectile points—the oldest arrowheads ever found—dating to the time of the eruption. It’s likely that humans in the region invented archery to hunt animals that had moved farther afield as ecosystems shifted.
These weren’t the only innovations sparked by necessity. Geological evidence from the same site shows that early humans diversified their diets. Alongside hunting wildebeests, ostriches, and monkeys, they began consuming more fish—an abundant resource as seasonal waterways dried into shallow pools. It’s a story of resilience and flexibility: when the world changed, humans adapted, because that’s what we do.
Not the Only Supervolcano in Town
While Toba is ancient history, humanity isn’t done with supervolcanoes yet. In fact, there’s one right now rumbling under Italy: the Campi Flegrei caldera (or the Phlegraean Fields, for those of us who can’t pronounce ancient Greek). Located just outside Naples, this massive volcanic system is making experts very nervous. Over the past several years, it’s been shifting and rumbling ominously, causing some researchers to start discussing potential evacuations.
Campi Flegrei isn’t some quiet, unassuming geological feature. The last time it erupted on a large scale, around 39,000 years ago, it likely contributed to the extinction of Neanderthals. And while it hasn’t had a major event in centuries, recent activity suggests it could be gearing up for something big.
The sheer energy of a supervolcano is hard to fathom—imagine the destructive force of a typical volcano, then multiply it a few hundred times. It’s terrifying, but also awe-inspiring.
A Force of Nature and a Catalyst for Change
Volcanoes like Toba and Campi Flegrei are more than natural disasters—they’re reminders of Earth’s immense power to shape, destroy, and renew. I’ve always been fascinated by them, not because I’m obsessed with disasters (I’m not—I promise), but because of their sheer scale and their ability to transform the world and human lives. They’re like nature’s reset button, wiping the slate clean and forcing new ways of thinking, living, and surviving.
That’s why volcanoes play such a pivotal role in my Magorian and Jones series. By the time that story wraps up, volcanic eruptions are the ultimate harbingers of change, reshaping Earth and setting the stage for the Scorched Lands Saga. But it’s not the destruction that interests me most—it’s the aftermath. What comes after the fire, the ash, and the smoke? How do humans adapt and rebuild in the face of such overwhelming power?
Toba’s eruption didn’t destroy humanity. It challenged us to innovate, to rethink, to survive. It’s a story as old as time and as relevant as ever—especially with places like Campi Flegrei reminding us that Earth still has a few tricks up its sleeve. And while we may not be facing a Toba-scale eruption anytime soon (fingers crossed), we can still learn from the past. After all, if our ancestors could handle the world’s most violent eruption, surely we can figure out how to handle whatever comes next.
