Hello, readers friends. What would happen to your head if I told you that the plane of the world that you have known all your life is not correct? To begin with, some of the aspects of the world map that we take for granted are completely arbitrary. We are used to seeing America on the left and Asia on the right. But the world is a sphere and its surface has no edges; So for the Americans, Asia is left to the West and Europe to the East. What happens is that we have adopted a convention in which Europe is at the center of the map.

On March 22, 2014, at 10:37 AM, a massive mudslide occurred 4 miles east of Oso, Washington. It engulfed a rural suburb of the town, killing 43 people and destroying even more homes. It was the deadliest single landslide in American history (outside ones caused by volcanoes, earthquakes, and dam collapses), and all of those deaths could have been easily prevented.

Within days, county officials began claiming that it was "completely unforseen" and "came out of nowhere." One noted that "A slide of this magnitude is very difficult to predict. There was no indication, no indication at all." Except, well, there had been. There'd been a 2010 report commissioned by Snohomish County that explicitly warned that the hillside in question was one of the most dangerous in the United States, and that knowledge of its risks dated back decades- the area was even known among locals as "Slide Hill." Known mass wasting events (the larger category that includes landslides, mudslides, and more) occurred in 1937, 1951, 1952, 1967, 1988, and 2006.
