Etymology
Description
The Bagre Norte Fault branches from the Palestina Fault, close to the Alicante River. The fault juxtaposes Precambrian metamorphic rocks on the east against sedimentary rocks in the west. The fault shows as a prominent topographic lineament on satellite images and aerial photographs. Prominent scarp faces west, the fault appears to displace erosion surfaces of the Central Ranges about 200 metres (660 ft). The strong geomorphologic expression suggests Quaternary activity.[1]
