How do you achieve the Mam Tor condition?
By analogy with Mam Tor, this condition has been attained after a long sequence of secondary slips leading progressively to more stable configurations in which reactivation occurs only in heavier (and less frequent) rainfall, until finally the slide mass remains stable even in the most severe rainstorms.
