April 2010 Baja Earthquake

On April 4, 2010, a 7.2 earthquake struck the northern Baja California and Southern California region. I was in Oceanside at a friends house at the time. Initially, I didn’t feel it and thought the others at the party were joking. We had been talking about the Northridge Earthquake earlier in the day. Once I stepped out onto the patio, I felt the ground moving. I knew it was large but farther away. My first thought was – What just happened to Los Angeles? Instead of Los Angeles, it was the Mexicali/Calexico area that got hit the worst as it was much closer to the epicenter.

Wanting to survey the damage to the roadways in that area and see if any of the old bridges were damaged, I headed out the following weekend. As it was also springtime, parts of the desert were in bloom. The ocotillo in particular had a beautiful display of flowers. To get out there, I followed Hwy 80 out to the Desert View Tower. After talking with Ben, the owner, I headed out to Calexico following Hwy 80 and Hwy 98. I was hoping to see cracks in Hwy 98 from any fault movement but did not find any.

In Calexico, many buildings were damaged with a large portion of the older downtown area closed off until the buildings could be stabilized. The biggest damage I saw was at a hotel in the northwestern end of downtown. Parts of the walls and roof had collapsed.

Returning from Calexico, I stopped at a few bridges to see the fill on each side had settled, causing some cracking in the pavement. Additional cracks were spotted at the New River crossing on old US 80. Overall, the highways were lightly damaged with some concrete broken at some bridges.
