...theory, such forecasting should be easy. All tremors are preceded by small movements in the earth's crust. As these shifts occur, usually along existing faults in the crust, they cause a gradual buildup of stresses and strains that must eventually be released, sometimes violently...
...well as their elevation can be calculated with an accuracy of an inch, or even less.* If subsequent measurements months or years later reveal changes in the established distance between the antennas or their altitudes, it will be a sure sign of movement in the earth's crust...

But they spotted only small mountains-a sign of minor uplifting by forces beneath the earth's crust. The new observations, he explained, suggest that the continents are being pulled apart and hauled along by semimolten rock moving like two giant conveyor belts in opposite directions...
...indicated that the molten rock had not been forced out under tremendous pressure. On the contrary, it seemed to have simply peaked from the interior of the earth through cracks created as the earth's surface was stretched. Explained Bryan: "Like a cobblestone street, the earth's crust can be pulled apart very easily. And it is the rift valley where this fracturing is occurring...
