Falla de San Andrés

The old road that links the towns of Tiñor and San Andrés takes us round to the eastern flank of the oldest volcanic edifice on the island: the Tiñor face. For 4kms. it is possible to see the plateau of the FALLA DE SAN ANDRÉS (The SAN ANDRÉS FAULT) which has been partially covered by more recent lava flows. This volcanic fault which looks NE – SW, triggered the fissure and landslide of hundreds of metres of this flank of the volcanic edifice over 250,000 years ago.
