Rockslide in Frank
The landslide in Frank or Frank Slide occurred on April 29, 1903 near Frank, a village with 100 inhabitants in the Crowsnest Pass community in the Canadian province of Alberta , about 250 kilometers south of Calgary , in the Rocky Mountains .
A compact block of a summit cliff of around 30 million cubic meters (maximum dimensions: 150 meters deep, 425 meters high, 1010 meters wide) broke off at 4:10 a.m. at the summit of Turtle Mountain and fell over a flank of an average of 45 ° around 1000 meters into the deep. A destroyed rubble area of around three square kilometers was created.
The whole event was over in less than 90 seconds, with the actual crash likely to have lasted no more than five to eight seconds. Around 70 people lost their lives, some were injured, and a passenger train was stopped in time. Around 40 buildings, the two-kilometer railway line and a driveway were destroyed. A small reservoir was created.
