The animated slides, which were created using images from Google Earth and DigitalGlobe by Greek earthquake geologist Sotiris Valkaniotis, show how the quake caused part of the Earth to move northwest while simultaneously jolting another side of the fault southeast along the surface of the Mojave Desert.

“I've never seen this before,” Brian Olson, engineering geologist with the California Geological Survey, recently told the LA Times.

“It's really dramatic and a super-good illustrator, even for the advanced scientists, all the way down to the grade-school kids,” Olson continued, adding that the images “show the scale and permanency of movement — this ground moved in places up to 13 feet, permanently. It's not going back.”
The July 5 earthquake took place one day after a 6.4-magnitude tremor struck 122 miles northeast of Los Angeles.
According to Glenn Biasi, a geophysicist with the United States Geological Survey (USGS) in Pasadena, California, “the earthquakes of the [July] 4th and 5th occurred in what we call a fault zone," Sputnik reported.
According to the USGS, “a fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep … During an earthquake, the rock on one side of the fault suddenly slips with respect to the other."
