Northridge, Calif.

[skipwords]InSAR radar once again provides a detailed look at the seismic activity of a powerful earthquake. Pictured here are combined radar images of the Northridge, Calif., earthquake, a magnitude-6.7 tumbler that shook the region on Jan. 17, 1994. This earthquake killed 60 people, injured thousands and caused an estimated $20 billion in damage throughout southern California.

 

The fault slipped two to three meters (6.5 to 9.8 feet) during the shaker. This image from NASA allows experts to see the small shifts in position of the Earth’s surface, which is shown here by arrows. [/skipwords]
