California quake leaves scar on the desert

That's an quake every 1 minute and 7 seconds.

Around 10:30 in the morning on July 4, a 6.4 magnitude natural disaster struck near Ridgecrest, California.

That satellite gathers data using a technique called synthetic aperture radar, which produces detailed measurements of the height of Earth's surface.

NASA says that each dark colored band represents 4.8 inches (12 centimeters) of displacement and the "noisy" areas - stippled dots of color that congregate in the center of the image - are where the Earth was broken apart by the temblor.

And the "noisy" areas in the northwest indicates where the ground surface was disturbed.

President Trump announced Monday the approval of an emergency declaration for assistance in the towns affected by the recent earthquakes in the Ridgecrest area.

To drive this need for a plan home, "the United States Geological Survey (USGS) warned that another quake of a similar magnitude could strike within the next week, while aftershocks have occurred an average of once a minute since Friday night". As the sun rose the following day, it became evident that the quake had ripped open a new fissure in the earth, visible from space satellite imagery.

A month before the two earthquakes, the USGS said a swarm of over 400 small earthquakes had been recorded in Southern California's Inland Empire, NDT reported.

It's part of a sequence of earthquakes that began rippling across the region last week and was preceded, less than 36 hours earlier, by a magnitude 6.4 foreshock on July 4.

The Planet Labs images also show a new darker line to the left of the epicentre, which its CEO Will Marshall said on Twitter was evidence of dewatering.

The earthquakes caused a number of minor injuries but no deaths.
