April 2010 Baja Quake – Part 2

In July 2010, I was able to go to Baja California with a friend. Part of our route traversed Federal Highway 2 (Mexico), which suffered some damage from the April 2010 quake. Hwy 2 had been repaired but the adjacent old alignment had not been. I was rather amazed at the amount of offset from this earthquake. I observed about 2′ of horizontal and about 5′ of vertical offset at the highway crossing.

East of the fault, bridge embankments on the Hwy 2 Mexicali Bypass show signs of settling.
