The Tunguska event
Siberia, 1908 · “The Second Sun”
On the morning of 30 June 1908, something from space exploded in the sky over central Siberia and flattened a forest larger than a city. The Short follows Darya, a fictional storekeeper at the Vanavara trading post, about 60 km away, through the minutes before and after. This is the history behind it.

The day, hour by hour
- 30 June · before 7 am
A summer morning at the post
Vanavara was a trading post on the Podkamennaya Tunguska river, where Russian merchants traded with Evenk reindeer herders.15
DARYAFurs in, flour and tea out. Nothing ever happens here!
- About 7:14 am
A second sun
Witnesses saw a fireball brighter than the Sun cross the sky. An Evenk witness said it was "as if a second sun appeared".1
KOLYAMama, look! There's a second sun in the sky!
- Moments later
The sky splits
The object exploded several kilometres above the forest. At Vanavara, a man named Semenov, sitting on his porch at breakfast, said "the sky was split in two" and felt heat as if his shirt had caught fire.12
SIBERIA30 JUN 1908 07:14 - The blast wave
Thrown off his feet
Semenov was thrown several metres and the trading post's windows were blown out.12 Around the blast site, about 2,150 km² of forest was flattened.13
DARYAAway from the windows, Kolya! Run!
- That day
The dead
At least three people died, all Evenki, along with many reindeer. The area was remote and almost empty, and the full toll is unknown.14
- 1927
No crater
Nobody reached the site until Leonid Kulik's expedition, 19 years later. He expected a giant crater and found none: at the centre, trees still standing but stripped bare, and further out, trees flattened in a ring pointing away from it.23

Nobody reached the blast site until 1927, 19 years later.
They expected a giant crater. They found none.
Darya is fictional. The missing crater is real.
Every line, checked
Each line from the Short that makes a historical claim, beside what the record says.

Furs in, flour and tea out. Nothing ever happens here!
Vanavara was founded around 1899 as a trading post where merchants traded goods with the Evenki. This comes from a local history source.5 Darya and her store are our invention.
Medium
Mama, look! There's a second sun in the sky!

Mama! The sky split in two!
Windows shattered 60 km away. About 2,150 square km of forest fell flat.
At least three people died, all Evenki. Almost nobody lived nearby.
They expected a giant crater. They found none.
Open question
Why was there no crater?
Most scientists think a stony space rock about 50 to 60 metres wide exploded 5 to 10 km up, before it ever reached the ground. A comet has also been proposed, and the details are still debated.1
For nights afterwards, skies across Europe and Asia glowed so brightly that people could read a newspaper at midnight.12
MediumThink about it
- Nobody reached the site for 19 years. What made it so hard, and what evidence might have been lost in that time?
- Kulik expected a crater because that is what impacts usually leave. How can expectations shape what an investigator looks for?
- Much of what we know comes from witnesses interviewed years later. How reliable are memories recorded long after an event?
- Why might an explosion this large have had so few known victims?
