The iconic Space Needle in Seattle was completed #OTD in 1961. When it opened just over a year later as the centerpiece for the 1962 World’s Fair, the 605-foot-tall observation tower was the tallest structure west of the Mississippi River.

December 2, 1959, constructed five years earlier, the Malpasset dam collapses - the first arch dam that had ever failed. The resulting wave floods the French town of Frejus, killing 423 people.

The underlying cause of the dreadful disaster in #Indonesia may have been landslides triggered by intense rainfall, which transitioned into channelised debris flows and mudflows. This Planet Labs imagery shows an area south of Padang Pajang in Sumatra. There are many, many landslides.

Anders Celsius, a Swedish astronomer, physicist, and mathematician, was born on this day. He founded the Uppsala Astronomical Observatory in 1741 and, in 1742, proposed the Celsius temperature scale, which bears his name.

It produced an eight-metre high tsunami that swept into the coast of the island.
It killed nearly 30 people.

On Nov. 14, 1938, the Lions Gate Bridge opened in Vancouver.
The bridge only took 593 days to build, and it wouldn't have happened without the wealthy Guinness family.
A bylaw also prevented any Asian person from helping in construction of the bridge.

The Tacoma Narrows Bridge collapsed because of the physical phenomenon known as aeroelastic flutter. Before the bridge opened, high winds would cause the bridge to move vertically, giving the nickname Galloping Gertie.

The redevelopment of Postdamer Platz in Berlin was the largest project in Germany in the 1990s. Even the small Bavarian consulting firm I worked for at the time got a piece of the action.
