Yesterday's earthquake has wreaked unprecedented havoc on Taiwan's infrastructure. Among services affected so far are:
The cities and counties most seriously affected by bridge and road collapses are Taichung County, Nantou City and County, Chiayi County, and Yunlin County.
The earliest date by which roads in Yunlin and Chiayi Counties will be fully operational again is estimated at three days from now, while repair of severe road damage in the more seriously affected Taichung and Nantou counties will take at least two to three months. The national freeways linking the north and south of the island were not affected.
Taipei's Mass Rapid transit system (MRT)
Operation of the three lines of Taipei Mass Rapid Transit system (MRT) was suspended early Tuesday, due to electricity shortages in Taipei city. The Mucha Line resumed operating at noon yesterday, while the Tamshui Line and Chungho Line restarted operations later in the afternoon.
Most train services resumed yesterday, though one section from Taichung to Miaoli is expected to resume today.
The port of Taichung, one of the four international ports located in Taiwan, has been seriously damaged, with five of its wharfs having reportedly collapsed. Officials from the Ministry of Transportation and Communi-cation (MOTC) estimated repair costs of about NT$2 billion, and don't expect the damaged wharfs to become fully operational for two years. Officials suggest ships planning to dock at this harbor divert to the southern Kaohsiung Harbor or Keelung Harbor in the north.
Neither domestic nor international air services were affected by the disaster, MOTC officials said.
The earthquake knocked out Taipower's Chungliao power substation in Nantou County, leaving all areas north of Changhua in darkness. The Chungliao substation is one of Taipower's three major substations in Taiwan. Taipower sent investigators to the Chungliao substation by helicop-ter.
Power generators at Taipower's first and second nuclear power plants were shut down by the quake. At least five hydroelectric and thermal power plants across northern Taiwan were also affected.
The earthquake also paralyzed hydroelectric stations and substations along the Tachia River watershed in central Taiwan. Taipower teams were unable to reach the stations yesterday as roads leading to the plants had been cut off.
Overall, electricity was cut off to an estimated 6.5 million house-holds, about two-thirds of Taiwan. By 5am yesterday morning, power had been restored to important facilities in northern Taiwan, including government agencies, CKS airport, bus, train, and MRT stations, hospitals and water supply facilities.
Taipower officials said they hoped to restore power to 75 percent of households in northern Taiwan sometime today. But power for industrial use might take longer. Full restoration of Taiwan's power grid may take two days, the officials said
Water and Reservoirs
The earthquake also seriously damaged some of the major reservoirs in central Taiwan, cutting water supply to parts of Taichung County, Changhua County, and the Hsinchu Science-based Industrial Park.
The Sun Moon Lake Reservoir in Nantao County suffered a 150-meter-long, 5cm-wide crack.
The Shihkangpa and Liyutan reservoirs on the Tali River in Taichung County were also severely damaged by the earthquake.
