Satellite images from the NASA Earth Observatory show the scale of destruction in Turkey and Syria after massive earthquakes left over 20,000 people dead and millions displaced.
The magnitude 7.8 and 7.5 quakes struck southern Turkey and western Syria on Feb. 6. Eric Fielding, a geophysicist at NASA's Jet Propulsion Laboratory, said that the "very large and powerful earthquakes" did damage similar to the 1906 earthquake that "destroyed San Francisco."
The earthquakes "ruptured all the way up to the surface over a long series of fault segments," Fielding said.
