These slips (white streaks) occurred in the hills north-west of Napier after Cyclone Bola hit from the north in 1988. Rain fell on these steep hills, which had been cleared for farmland. As soils became sodden, the upper layers separated from lower layers and slid down the slopes. Soils such as these, derived from soft mudstone rocks, are particularly vulnerable to slips following heavy rain.
