The fault had moved six days ago, triggering the terrifying tremor that felled churches, left nearly 200 dead, and rendered scores homeless.
The wall, or the face of the fault, is the edge of a large area of land that had been thrust upwards as high as three meters. It stretched as far as the eyes can see, cutting off roads and numerous trails. The fault line's direction runs northeast to southwest through this barangay, which is located in the municipality of Inabanga.
"Nahati ang Bohol," said Leonila Divinagracia, a barangay kagawad here, observing that a wide swath of the province was now more elevated with a clear demarcation.
Still unnamed, the prominent formation here is unique in the annals of the country's recent geological history. It’s considered a “reverse fault†because of the vertical surface rupture, a sign of the enormous energy packed by last Tuesday's cataclysm. Less powerful quakes cause land to sink rather than rise.
The last great earthquake in the country, in northern Luzon in 1990, was caused by a lateral (side to side) movement of a fault, and did not leave a similarly large mark on the terrain.
