Areas Near Southern End of Fault: Mingjian, Jiji, Jungliau, and Jushan

     

An eight-story building collapsed as others stood up. There was no casualty as the building was evacuated before it collapsed during aftershocks. (N 23.837 E 120.7030).
Surface expression of fault passing through rice patty and road, near intersection of Highways 3 and 152 in Mingjian (N 23.8312 E 120.7096). Vertical offset at this location was about 2 m.

     

Immediately north of previous photograph, the fault rupture passes adjacent to this transmission tower (N 23.8351 E 120.7100). Tower number is 057.
Drainage channel near transmission tower was offset by the fault (N 23.8351 E 120.7100). Approximately 2 m vertical displacement was measured. Tower 057 visible in background.


     

View of creek adjacent to Tower 057 (N 23.8351 E 120.7100). Liquefaction in the creek produced a large sediment boil (next photo).
Sediment boil in creek bed near Tower 057 (N 23.8351 E 120.7100).


     

Immediately north of Tower 057, this railroad track was offset by surface faulting at a bridge (N 23.8351 E 120.7100). Based on visual observation, displacement estimated as > 2m vertical and ~ 1m right-lateral strike-slip.
Away from the bridge, another section of the railway track buckled due to secondary fault surface rupture (N 23.8351 E 120.7100).

     

Close to the bridge the railway track buckled due to compression and failed at the rail joints (N 23.8351 E 120.7100).
The rail slid on its track about 25 cm at this location (N 23.8351 E 120.7100).


     

The retaining wall was compressed about 2.1 m due to the fault surface rupture (N 23.8351 E 120.7100).
Failed retaining wall between gas station and bridge abutment, on Highway 152 between Mingjian and JiJi (N 23.8357 E 120.7260). A creek is located at the base of the wall.


     

Another view of toppled retaining wall (N 23.8357 E 120.7260).
Settlement of abutment adjacent to bridge along Highway 152, between Mingjian and Jiji (N 23.8288 E 120.7515). Measured settlement was 1.04 m. Some of the settlement can be attributed to outward movement of the abutment wall.


     

Soft story failure of building in Jiji (N 23.8314 E 120.7936). Many buildings in Jiji experienced this type of failure. No significant settlement of building foundations was observed driving through the town.
Collapsed temple in Jiji (N 23.8314 E 120.7936).


     

Head scarp of slide at Jungliau Power Station (N 23.8927 E120.7690). Much of the power shortages in Taiwan were traced to the damage at this switchyard. Displacements across cracks near the scarp were about 0.6 m (V) and 0.15-0.3 m (H).
Deformation across slide boundary at Jungliau Power Station (N 23.8927 E120.7690). Photographer is standing on slide. Horizontal movement at this location was estimated to be about 1 m.


     

Deformation of wall crossing slide boundary at Jungliau Power Station (N 23.8927 E120.7690).
Fault rupture through small temple in Jushan (N 23.7680 E 120.7092). Fortuitously, two independent buildings were connected above the fault, so the surface rupture did not cause a collapse. Vertical offset at this location was about 1 m.


     

Collapsed temple in Jushan near fault rupture (N 23.772 E 120.7094).
