The damage and the rehabilitation process after 1990 Luzon earthquake - some cases of La Union and Nueva Ecija

The 1990 Luzon earthquake hit northern and central part of the Luzon island on 16 of July which induced several types of damage. The damage varied widely with the cause and the place. In the coastal area of the Lingayen Gulf, the main cause of the damage was liquefaction. Some of them were very large in scale, so that they made settlements sunk. In the mountain area along the fault, great many landslides triggered by shaking, and strong motion itself did damage during the earthquake. In a few months after that, typhoon rains sometimes caused floods, and the houses and farmland were washed out or buried by the material supplied by the landslides. The affected people were helped by the various kinds of assistance projects by the governmental organizations or NGOs. The authors have found two types of the resettlement based on people's own initiative and by the initiative of the governmental organizations or NGOs. There are certain difficulties in each type of the resettlement. -from Authors
