Disasters, whether natural or man‑made, scar both landscape and lives. As years roll by the wounds fade and the stories drift into the shadows. Below are ten lesser known catastrophes from the 20th century that still deserve a moment of remembrance.
10 The Paris Métro Fire
The Paris Métropolitain, fresh off its 1900 debut, was already riddled with flaws. Wooden carriages, insufficient ventilation, and cramped exits made the underground a tinderbox. On August 10, 1903, a chain of mishaps ignited a tragedy that claimed 84 lives.
It started when a train bound for Ménilmontant broke down. A second train was attached as a pusher, and passengers from both were forced into a third, already overcrowded carriage. Faulty wiring sparked a small fire, but instead of stopping, the driver of the second train accelerated, hoping to reach Ménilmontant quickly.
The surge of air fed the flames, and moments later the first train’s engine detonated, sending a fireball through the wooden cars of both trains. Crews fled into darkness as the lights blew out.
Guards warned the third train’s passengers to evacuate, but they were left stumbling through a smoke‑filled tunnel, either forward toward Ménilmontant or back toward Les Couronnes. The latter station remained open, and a rush‑hour crowd blocked any chance of escape, sparking panic.
When firefighters arrived, bodies were piled to the ceiling on the Les Couronnes platform. Most victims died from smoke inhalation; some even clawed at brick walls in desperation. In a bizarre twist, eleven more corpses were found in the ticket office, where they had smashed windows trying to reclaim a one‑penny fare.
In the aftermath, four trainmen were convicted for their roles in the disaster.
9 The Sinking of the USS Squalus
SS‑192, better known as the USS Squalus, was conducting test dives in the North Atlantic on May 23, 1939, when a valve failure at just fifty feet sent water flooding the engine compartment. The submarine plummeted to a depth of 243 feet, sealing its fate for the crew.
Only the 33 men stationed in the control room and forward torpedo room survived the initial plunge; the rest of the crew, including two civilians, perished as the forward battery and both engine rooms flooded.
After a broken telephone buoy and a flurry of rockets, the trapped sailors conserved their dwindling air, illuminated only by handheld lanterns while slow leaks persisted. Their rescue hinged on a daring operation using a specially equipped rescue bell.
Divers attached the bell’s 5×7‑foot chamber to a hatch, supplying oxygen and a telephone line. Survivors were hoisted out in groups of nine. By the early hours of May 25, the last of the 29‑hour ordeal ended as the final men were lifted to the surface.
Months later, pontoons were affixed to the sub, and after 113 days the vessel was raised and towed to Portsmouth Navy Yard. Recommissioned as USS Sailfish in May 1940, it served throughout World War II before decommissioning in 1945.
8 The Mitsui Miike Mine Explosion
On November 9, 1963, the Mitsui Miike coal mine on Kyushu’s southern coast erupted in a catastrophic blast. Over 1,300 miners were underground during a shift change when a massive coal‑dust cloud ignited, detonating roughly 500 yards from the entrance.
While safety protocols existed, labor disputes, mass layoffs, and a reduced safety staff led to lax enforcement. Poor ventilation compounded the danger.
The explosion shattered tunnels and flooded the mine with lethal carbon monoxide. Some workers escaped through connecting tunnels; many others succumbed to the toxic gas.
Rescue teams delayed their response until 6:30 PM—over three hours after the blast—finding at least a hundred bodies near the personnel carrier. In total, 458 miners died and more than 800 suffered carbon‑monoxide poisoning.
The incident highlighted the company’s poor safety record; 19 officials were later charged with negligence after a 1984 mine fire that claimed another 84 lives.
7 The Los Angeles Flood
From February 27 to early March 1938, a relentless storm drenched Southern California, delivering the worst flooding the region had seen in a century. Five days of nonstop rain swelled the San Gabriel Mountains’ rivers, sending water surging through Los Angeles, Riverside, and Orange Counties.
To protect the Big Tujunga Dam, officials opened its gates, unleashing torrents that turned movie studios into islands and stranded Hollywood stars at their ranches. In Universal City, the Lankershim Boulevard Bridge was swept away, killing five people.
Railways, bridges, roads, and telegraph lines were destroyed. Downtown Los Angeles even saw perch swimming in gutters, a testament to the water’s depth. Radio reports exaggerated the situation, stoking panic.
By the end of the deluge, 115 people had perished, thousands were homeless, and property damage ran into the multi‑million‑dollar range.
6 The SS Morro Castle Fire
The turbo‑electric liner SS Morro Castle, touted as the “millionaire’s yacht,” met a fiery end on September 8, 1934. Pressured to maximize profit during the Depression, the ship’s schedule left little time for maintenance, and a high crew turnover meant many were unfamiliar with safety protocols.
A lawsuit from a passenger led Captain Wilmott to cancel emergency drills. He died of a heart attack the night before the disaster, and First Officer William Warms—who had little respect from the crew—took command.
At around 3 A.M., a crewman reported smoke from a passenger lounge. An officer discovered a full‑blown blaze, but untrained crew members fumbled with the fire‑suppression equipment. Warms, distracted by a near‑hurricane‑strength storm, delayed ordering passengers into lifeboats, many of whom were terrified or intoxicated.
The fire raged unchecked. Warms steered the ship toward the New Jersey shore, five miles off Manasquan. Passengers leapt into cold, storm‑tossed waters; only six lifeboats were launched, mostly carrying crew.
In total, 86 passengers and 49 crew members perished, their bodies washing ashore over time.
5 The Meuse Valley’s Killer Fog
Lesser Known Fog Mystery
Between December 1 and 5, 1930, a dense, cold fog settled over Belgium’s Meuse Valley, cloaking a 15‑mile stretch from Huy to Liège. The region’s factories—chemical plants, zinc smelters, and coke ovens—spouted a constant plume of pollutants.
The fog, caused by a temperature inversion, reduced visibility to a few feet and irritated eyes and throats. By day two, residents, especially infants and the elderly, exhibited severe respiratory distress, and doctors were baffled by the sudden “disease.”
On December 3, a single day, 30 people died; the death toll continued to climb. Investigators suspected toxic fumes from the factories, which kept operating despite the emergency. Residents sealed their homes with paper and rags, even moving cattle indoors.
At the time, the term “smog” was still nascent, and rumors swirled—from supernatural origins to hidden German poison‑gas caches from World War I.
When the fog finally lifted, between 60 and 75 people had died, thousands more were ill, and many suffered lasting injuries. Two years later, Belgian authorities confirmed that the trapped fog, combined with industrial emissions, caused the tragedy.
4 Sinking of the Ferry Heraklion
The 498‑foot Greek steamship SS Heraklion, captained by Vernikos, ferried passengers between Crete and the mainland. On December 7, 1966, a delayed refrigerated trailer carrying oranges arrived late, forcing the crew to hurriedly secure it in front of the loading doors.
Overloaded with cargo and passengers, the vessel set sail for Piraeus. A severe gale, with winds up to 63 mph, battered the ship. The trailer broke free, slamming into the loading doors repeatedly until they gave way, allowing seawater to flood the hull.
The ship sank in just 20 minutes. Untrained officers and a panicked crew left passengers scrambling for exits. Approximately 268 passengers and crew perished, including the captain, while 46 survivors clung to life jackets amidst floating oranges.
The owners, Typaldos Line, faced negligence charges after the disaster.
3 Martinique Volcano Eruption
On May 8, 1902, Mount Pelée on Martinique erupted with a terrifying force. Residents of St. Pierre, the nearby waterfront town, had grown complacent, assuming lava moved slowly enough to allow escape.
Weeks of ash showers, tremors, and foul‑smelling gases preceded the cataclysm. Insects swarmed, poisonous snakes killed dozens of children, and the Etang Sec crater boiled, flooding River Blanche and killing 23 workers at a rum distillery.
On the morning of May 8, just before 8 A.M., Pelée unleashed a superheated avalanche of ash, rocks, and gas that raced downhill at lethal speed. The eruption incinerated everything in its path, killing more than 2,500 people almost instantly, most from inhaling air hotter than 3,000 °F.
Ships in the harbor were destroyed, and the town of St. Pierre was buried under a thick layer of volcanic ash. Only two residents survived the disaster.
2 The Modane Train Derailment
During World War I, on December 12, 1917, a French troop train bound for Lyon was overloaded with 19 wooden carriages pulled by a single locomotive. Officials ignored warnings about the dangerous weight, and an Army officer threatened the driver with a pistol to proceed.
As the train descended the steep four‑mile grade near Modane, the brakes overheated and ignited, setting the carriages ablaze. At about 75 mph, the first carriage jumped the rails, derailing the train.
The wreckage burned fiercely, leaving many bodies unidentifiable. An estimated 800 people died, and the French government kept the tragedy secret for over a decade until the surviving driver revealed the truth.
1 Naples Building Collapse
Following the violent eruption of Mt. Vesuvius in early April 1906, ash and cinders blanketed Naples. On April 11, a massive accumulation of ash caused the roof of the 600‑square‑foot Monte Oliveto marketplace to collapse.
The market, bustling with vendors and shoppers, featured a sturdy iron framework topped by a wooden roof—adequate for ordinary weather but no match for the three‑plus feet of volcanic ash that piled over the city.
Shortly after a religious procession passed by, the roof gave way without warning. More than 200 people were trapped beneath the debris. Rescue crews worked tirelessly, pulling bodies and survivors by hand.
When the last victim was recovered, the toll stood at 14 dead and at least 178 injured. The disaster foreshadowed later tragedies caused by ash‑laden roofs, such as the 1910 collapse of a church in San Giuseppe that killed 105 people.
