Answer:

Damage to Particular Buildings in Manila

The severe damage area was concentrated in a relatively small part of Greater Manila. This part of Manila lies in the mouth of Pasig River (a major river system in Metro Manila) and includes the deepest and most recent alluvial deposits in the city.

Ruby Tower

The Ruby Tower was a large six-storey building containing 38 commercial units in its first two floors and 76 residential units in its upper four floors. Most of the building collapsed except for a part of the northern end of first and second floors (Photo 1 & 2), killing 268 persons and injuring 260 of the occupants. The upper floors fell southwards while the southern end of the roof moved about 30 feet or 9.15 meters south and 10 feet or3.05 meters east (Photo 3). The lower floors appeared to fall close to their plan position (Photo 4).

Philippine Bar Association Building

The Philippine bar Association (PBA) was a medium rise six-storey commercial building with offices and club rooms (Photo 5). Most of the first storey columns suffered total collapsed or very severe damage and shortening (Photo 6, 7, 8 & 9). The intensity of damage increased towards the southeast end of the building. Exterior columns suffered greater damage and shortening the nearby interior columns. This resulted in very a severe deformation of some interior beams and part of the floor at each storey level.

Aloha Theater

The Aloha Theater is a large eight-storey building that suffered severe damage near its southern end. The damage was initiated by the collapsed of a few very short columns towards the southern end of the fourth floor. It spread out and severely damaging the southern end of the building (Photo 10 & 11).

Tuason Building

Tuason Building is a medium sized six-storey building which suffered severe damage or very close to collapse (Photo 12 & 13). The columns along the southern side wrecked or severely damage (Photo 14).
