A. COLLAPSED PILARCITOS 30-INCH WROUGHT-IRON PIPE LINE, NEAR 
TRESTLE CROSSING THE FAULT. 
The slip produced a compression on the pipe line which buckled it, thereby throwing down 
the trestle support. The consequent parting of the pipe line suddenly released the water 
from the pipe, causing a vacuum which brought about the collapse. Photograph by
