Benxihu Colliery accident in Manchukuo leaves 1,549 Chinese miners dead.

On April 26, 1942, a catastrophic fire at the Benxihu Colliery in Japanese-occupied Manchukuo killed 1,549 Chinese miners, making it the deadliest coal mining disaster in history.
The Benxihu Colliery accident occurred when an underground fire broke out at the Japanese-run coal mine in Liaoning Province. Rescue efforts were hampered by the complex tunnel network and lack of proper safety equipment. The use of hydraulic systems to seal the fire inadvertently trapped workers underground. Over 1,500 Chinese miners lost their lives, making it the deadliest coal mining disaster to date. The incident highlighted the dangerous working conditions imposed by the occupying forces. It also drew attention to colonial exploitation and forced labor practices. Following the accident, no significant safety reforms were implemented under Japanese administration. The disaster remains a somber example of industrial neglect and human cost during wartime occupation.

The Chernobyl disaster occurs in the Ukrainian Soviet Socialist Republic.

A reactor at the Chernobyl Nuclear Power Plant explodes, triggering the worst nuclear disaster in history in the Ukrainian SSR.
In the early hours of April 26, 1986, Reactor No. 4 at the Chernobyl Nuclear Power Plant suffered a catastrophic steam explosion. The disaster released massive amounts of radioactive material into the environment, contaminating vast areas across Europe. Emergency crews and plant operators risked lethal radiation exposure to contain fires and avert further explosions. The nearby town of Pripyat was evacuated days later, leaving behind an exclusion zone that remains restricted today. Chernobyl’s legacy prompted global reforms in nuclear safety and emergency response protocols.
