Environment : How does an earthquake fault line actually looked?

We read and hear  about earthquake fault lines but often times what we only see are representations of the fault line on maps as red lines or broken lines. We seldom see an actual photo of a fault line because  the physical gap, breach or trench on the surface of the earth had been filled up or covered with soil and plants due to the long passage of time after it occurred. Yesterday, a picture of the actual West Valley Fault or Marikina Fault Line  was put on the front cover of the Philippines Star. Scientists of Philvocs and Geosciences Australia are digging the actual trench/fault line for research and studies in relation to frequencies of  earthquakes in Metro Manila. Here's how an actual fault line or trench looks. (See second picture below)
