question:  What major change happened to the country's landscape as the tragedy continued?
context: It has happened a hundred times in the long history of Earth—and, sooner or later, will happen again! It was still a matter of academic interest when in the late '40s geologists speculated on the relationship between the Kiowa Fault and the Conchas Fault farther south, in New Mexico, and which followed the Pecos as far south as Texas. By the mid sixties it was definitely established that the three Faults were in fact a single line of fissure in the essential rock, stretching almost from the Canadian border well south of the New Mexico-Texas line. It strikes us today as ironic that from the late '50s there was grave concern about the level of the water table throughout the entire area. Not even in the Rockies could anyone remember a series of rock slides as bad as this. As the tremors grew bigger, along with the affected area, as several towns including Edison were shaken to pieces by incredible earthquakes, whole bus- and plane-loads of geologists set out for Colorado, without even waiting for their university and government department to approve budgets. They found themselves on the scene of what was fast becoming the most violent and widespread earthquake North America—probably the world—has ever seen in historic times. To describe it in the simplest terms, land east of the Fault was settling, and at a precipitous rate. East, where sharp reports and muffled wheezes told of continued buckling and dropping, the earth trembled downward. Atop the new cliffs, which seemed to grow by sudden inches from heaving rubble, dry earth fissured and trembled, sliding acres at a time to fall, smoking, into the bucking, heaving bottom of the depression. By 16 September the landslip had crept down the Huerfano River past Cedarwood. Land west of the Fault was holding firm, though Denver had recorded several small tremors; everywhere east of the Fault, to almost twenty miles away, the now-familiar lurch and steady fall had already sent several thousand Coloradans scurrying for safety. As the Fault moved north and south, new areas quivered into unwelcome life.
output:  Several states totally sink, and water takes its place.
options:  State lines were made to be different after the upsets by the earthquakes.  Much of the landscape is upset by the earthquakes, throwing dirt and dust everywhere.  Several states totally sink, and water takes its place.  New cliffs and fault lines continued to form.
