The 1991 Pinatubo eruption contributed a huge amount of sediment around Zambales, much of which were brought to the coastline through rivers draining the area. One such river is Bucao, which, empties out in Botolan. Eventually, the area around the mouth of Bucao River prograded and the new land was claimed and sold. New developments, including a beach resort, was built in the newly-formed land, but when a typhoon passed the area much of the sand was eroded away. Subsequent storms further ate the land up and the unfinished buildings were damaged beyond repair.
