The house in the background leaned as it stood on the fault scarp (24.28N, 120.78E, 16:05:13, October 2, 1999).

The fault surface rupture sheared and lifted up the green concrete slab of this warehouse in Fengyuan (24.27N, 120.75E, 15:03:26, October 2, 1999).
The fault surface rupture was almost vertical at one building corner. The total uplift was 5 meters (24.27N, 120.75E, 15:03:29, October 2, 1999).

The fault surface rupture cut through a U-shaped drainage channel and an adjacent warehouse (24.27N, 120.75E, 15:15:03, October 2, 1999)
A waterfall was created in the drainage channel as the thrust fault uplifted the section in the background (24.27N, 120.75E, 15:24:12, October 2, 1999)

The upper section of the retaining wall was uplifted by the thrust fault and the retaining wall was sheared. The asphalt road was reconstructed after the earthquake (24.28N, 120.78E, 16:04:09, October 2, 1999)

Another reverse fault segment (possibly a back-thrust) that cuts through a warehouse (N 24.27 E 120.75; 9/30/99)
Column failure due to differential ground movement from reverse fault displacement to the north of the warehouse (N 24.2733 E 120.7559; 9/30/99).

View to east across rice puddy that was level, but now has been up lifted about 5 m due to reverse fault displacement in northern Fengyan (N 24.2740 E 120.7559; 9/30/99)
Surface expression of fault with strike of N35E (note that all orientations are provided in terms of magnetic north) along street that is oriented roughly N60E in North Fengyuan; the fault crosses street in background; (N24.2746 E 120.7555; 9/30/99).

View to west of Shihkang Dam damage at right abutment (N 24.2832 E 120.7695; 9/30/99)
Relative uplift of approximately 9.3 m through right abutment of Shihkang Dam; vertical offset measured from top of dam south of fault to top of dam north of fault (N 24.2832 E 120.7695; 9/30/99).

Close-up view showing damage to dam components (N 24.2832 E 120.7695; 9/30/99)
Ground fissures in small town just north of bridge located just east of Shihkang Dam (N 24.2861 E 120.7801; 9/30/99).

Separation between previously adjacent buildings located over canal in town described in previous photograph (N 24.2861 E 120.7801; 9/30/99)
Ground cracking and building foundation damage in this town (N 24.286 E 120.780; 9/30/99).

View to east of east-west trending canal that used to flow to the east, but now flows west due to up lifting from reverse fault movement (N 24.2879 E 120.7821; 9/30/99)
Building tilted significantly due to fault movement (N 24.2879 E 120.7802; 9/30/99).

Retaining wall failure near surface expression of reverse fault segment south of trace fault that traverses Shihkang Dam (N 24.2772 E 120.7784; 9/30/99)
Fault movement tilted building (N 24.277 E 120.778; 9/30/99)

Relative ground movement resulted in this yard that was previously dry being inundated with water (N 24.277 E 120.780; 9/30/99)
View along fault affecting rail line and buildings in area south of Tachia River and to the northeast of the City of Fengyuan (N 24.2769 E 120.7768; 9/30/99)

Tilted building due to soft-story collapse in the City of Tungshih; the earthquake caused extensive damage and a significant number of deaths in this city; the damage was notably more concentrated in the western part of the city (N 24.2562 E 120.8224; 10/2/99)
Another soft-story collapse in the City of Tungshih; this site near the southern levee bordering the city also had several open ground cracks indicating lateral spreading toward the river (N 24.2550 E 120.8259: 10/2/99)

Soft-story collapse in the City of Tungshih (N 24.2641 E 120.8262; 10/2/99)
Close-up of building shown in previous photograph; this building was not in contact with any surrounding buildings and it fell in a north-south direction which is normal to the east-west orientation of the strike of the fault in this region (N 24.2641 E 120.8262; 10/2/99)

Multi-story building leaning in the City of Tungshih due to partial collapse of one story (N 24.264 E 120.826; 10/2/99).
