19 March 2023 - ONE OF THE WORST DAM FAILURES - ITALY

 

ONE OF THE WORST 

DAM FAILURES 

- ITALY -


G'day folks,

The sinister ruins of one of the worst dam failures of the 20th century lie in this astonishing alpine setting. 

In a growing modern nation craving for energy, as Italy was at the beginning of the 20th century, hydroelectric power was a synonym of progress, representing a victory of humankind over nature. Yet in the mountains of Bergamo province in Lombardy, that attempted feat would take a tragic turn. 

 

Construction of a hydroelectric dam to exploit the river Gleno in the the Valle di Scalve (Scalve valley) began in 1916, but the project was immediately cursed by poor materials and poor workmanship. On top of that, due to funding problems, the plan changed from the original idea of a gravity dam to a multiple-arch dam while the work was still in progress, resulting in a mixed-type dam.





 

Just after its completion, heavy rains filled the reservoir, and several leaks caused concern among the inhabitants of the valley below.

Sure enough on December 1, 1923, at 7:15 in the morning, the tragedy happened. The central section collapsed, causing a mass of 4.5 million cubic meters of water to pour into the villages in the Scalve valley. The official death toll counted 356 lives lost as a result of the flood, as well as massive damage to roads, bridges and buildings.

What remains of the dam is a 160-foot-high concrete barrage with a huge, chilling laceration in its central section. The sinister ruins are a stark and surreal contrast with the stunning alpine surroundings. 

6 May 2021 - INTERESTING FACTS ABOUT THE TITANIC

 

INTERESTING FACTS 

ABOUT THE TITANIC

G'day folks,

We've all heard about it, but here are some interesting facts.

April 15, 1912 — On her maiden voyage from Southampton to New York, the passenger liner Titanic hit an iceberg and sank on this day in history, resulting in the world’s worst peacetime shipping disaster.

Five days earlier the toweringly impressive ship — eleven storeys high, a sixth of a mile long and weighing 46,328 gross tons — slipped her moorings at Southampton to the cheers of awestruck crowds. She was the pride of the White Star Line, the biggest ship the world had seen, and certainly the best.

 For a single crossing the “millionaire suites” cost up to £870 ($1,200) — equivalent to about £44,000 ($62,000) today — and were designed, as one newspaper reported, “for the financial giants of our time: men who could lightly pay for this single voyage the year’s keep of ten British families.”

There was no shortage of takers for the ship's wondrous facilities. Leaders of industry, finance and commerce and figures from British and European aristocracy were joined by members of some of the wealthiest families in the United States.

They included Benjamin Guggenheim, whose fortune lay in mining, smelting and banking; Isidor Straus, whose money came from commerce and banking and his partnership in the famous Macy's department store; George Widener, son of tramway magnate P A B Widener, said to be the wealthiest man in Philadelphia; Charles Melville Hays, president of the Canadian Grand Truck Railroad; and John Jacob Astor, perhaps unkindly described by one journalist as “the world's greatest monument to unearned income.”

Astor had divorced in 1909 and two years later, at the age of 45, married 18-year-old Madeleine Force, a girl younger than his son, Vincent. Society was outraged and Astor went abroad with his young bride to escape criticism. They were now returning, Madeleine five months’ pregnant and Astor anxiously wondering if he would be able to regain his old position in New York society.

They and some 2,200 other souls were enjoying their sumptuous surroundings when, at 11.40pm on the fifth night out, lookout Fred Fleet, peering from the crow’s nest into a calm, clear night bursting with stars, spotted something directly ahead.



Walter Lord, in his book A Night to Remember, tells dramatically what happened next: “At first it was small, but every second it grew larger and closer. Quickly, Fleet banged the crow’s nest bell three times — the warning of danger ahead. At the same time he phoned the bridge. ‘What did you see?’ asked a calm voice at the other end. ‘Iceberg right ahead,’ replied Fleet.

“For the next 37 seconds Fleet watched the ice draw nearer. Now they were almost on top of it and still the ship didn’t turn. The ‘berg towered wet and glistening far above the forecastle deck and Fleet braced himself for a crash. Then, miraculously, the bow began to swing to port. At the last second the stern shot into the clear and the ice scraped swiftly by along the starboard side. It looked to Fleet like a close shave.”

He was mistaken. The jarring of a collision brought Captain Edward J Smith rushing from his cabin to the bridge, resulting in an exchange recounted at the subsequent inquiry in New York: “Mr Murdoch, what was that?”

“An iceberg, sir. I hard-a-starboarded and reversed the engines and I was going to hard-a-port around it, but she was too close.”

“Close the emergency doors,” Smith snapped. But First Officer William Murdoch had already thrown the switch that sent the massive doors crashing into place. The ship was divided into 16 watertight compartments which could be sealed by these doors in the event of an accident. This feature, in addition to the Titanic’s double bottom, prompted the Shipbuilder magazine to describe the great vessel, in what turned out to be a haunting epitaph, as “practically unsinkable.”

More colourfully, passenger Mrs Albert Caldwell, who boarded at Southampton, remembered asking a crewman if the ship really was safe. “Lady,” he replied, “God himself could not sink this ship.”

Thomas Andrews, managing director of Harland & Wolff, builders of the ship, made a tour of inspection and found that the first five compartments were flooding, suggesting a 300ft gash.

Andrews, wrote Walter Lord, explained to the captain what this meant: “The Titanic can float with any two of her 16 compartments flooded. She can even float with her first four compartments gone, but she cannot float with her first five compartments full.

"The bow will sink so low that water in the fifth compartment must overflow into the sixth. When this is full, it will overflow into the seventh, and so on. It is a mathematical certainty — the ship is doomed.”

As the crew began loading passengers into the pitifully few lifeboats, Second Officer Charles Lightoller was supervising the loading on a strict “women and children only” basis. He was at the centre of a much reported incident when John Jacob Astor helped his wife into boat No 4 then asked if he could join her. “She is,” he said, “in a delicate position.”

“No, sir,” Lightoller told him. “No men are allowed in these boats until the women are loaded first.” Astor had a fortune of $4,250 cash in his pocket at this time. “It was about as much use to him,” wrote Geoffrey Marcus in The Maiden Voyage, “as the $150 million he possessed ashore.”

There were 16 lifeboats, plus four “collapsibles”. Altogether, they could carry 1,178 people. But there were more than 2,200 aboard the Titanic.

One man who did step into a boat — he insisted at the subsequent British and American inquiries that it was being lowered, there was room in it and there was no one else around — was the White Star Line chairman J Bruce Ismay.

He later came under fierce criticism, summed up by Rear Admiral A T Mahan, speaking to reporters: “So long as there was a soul that could be saved, the obligation lay upon Mr Ismay that that one person — and not he — should have been in the boat.”

While the drama was unfolding, members of the ship’s orchestra helped to keep up morale by playing ragtime tunes. One of the myths that grew was that as the ship went down the musicians played the hymn Nearer My God to Thee.

2 March 2021 - THE COLLAPSE OF THE TECOMA NARROW BRIDGE

 

THE COLLAPSE OF THE 

TECOMA NARROW BRIDGE

 

G'day folks,

Welcome to another bridge disaster.

The Tacoma Narrow Bridge in Washington was a suspension bridge, spanning the Puget Sound between Tacoma and the Kitsap Penninsula. Sleek and slender, it was the third-longest suspension bridge in the world at the time, spanning over 5,959 feet. 

 It was clear during construction that the deck moved vertically in windy conditions, so much so that construction workers nicknamed the bridge Galloping Gertie. Nevertheless, the bridge was opened to the public on July 1, 1940. On November 1 that same year, high winds caused the bridge to sway considerably.

 


 

 At about 11 AM, the bridge's main span finally collapsed in the 40 mph (64 km/h) winds. The deck oscillated in an alternating twisting motion that gradually increased in amplitude until the deck tore apart. Fortunately, there were few people on the bridge at the time, and the only casualty was a dog named Tubby.


Clancy's comment: Wow. Poor Tubby!
