Scientists pored over seismograms, measured coastlines, and studied the scars left by subsidence and uplift. What had started as violent shaking and rolling waves became, under careful study, a geologic event that changed the course of science.\r\n\r\nThe earthquake was not just the largest in North America. It became a key event in the history of plate tectonics. According to the United States Geological Survey and later research, Alaska’s disaster was a megathrust rupture – the Pacific Plate sliding beneath the North American Plate, releasing centuries of strain in minutes. The magnitude and power of the quake, and the tsunami that followed, helped prove that continents are not fixed, and that the earth’s crust can move in ways that change coastlines in an instant.\r\n\r\nLearn more at: https://thedisasterarchive.com/disaster/alaska-earthquake-1964","author_name":"The Archive Network"}
