Sichuan Earthquake Update

Via @davely on Twitter.

A 20 to 30-ft high retaining wall in a subdivision in San Antonio Texas failed on Sunday causing an evacuation of 80 homes. After an initial inspection, some 55 home-owners were allowed to return.  The massive tension cracks that opened along the wall and behind it were 12-15-ft deep and 6-8-ft wide. Reportedly, the wall had problems even before the subdivision was even constructed. More after the break. (Photo by Jerry Lara – San Antonio Express-News)
