Yesterday's earthquake has wreaked unprecedented havoc on Taiwan's infrastructure. Among services affected so far are:
Roads

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.
Trains
Most train services resumed yesterday, though one section from Taichung to Miaoli is expected to resume today.
Ports
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.
Air Services
Neither domestic nor international air services were affected by the disaster, MOTC officials said.
Power outages
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.
The Shihkangpa Reservoir, which supplies water to the Greater Taichung and Changhua areas, leaked all two million tons of its water yesterday.
A water pipeline from Feng-yuan Water Treatment Plant to the Hsinchu Science-based Industrial Park was also seriously damaged.
Minister of Economic Affairs Wang Chih-kang (
Dams
Taipower warned that two of its hydroelectric dams in central Taiwan may have been damaged.
"Our technicians checked the Takuan and Mingtan dams and found abnormal signs," a Taipower official said without elaborating. "Further evaluations will be still needed to examine the structure of the two dams."
But he noted the structure of the largest dam in the area -- Tehchi reservoir -- remained intact despite damage to the power generating facilities.
The Feitsui Reservoir, which supplies water to the Greater Taipei area was not damaged, the official added.
Gas and oil
Of the 580-plus gas stations run by China Petroleum Corp (CPC), only 375 were in operation yesterday. Stations in the Taichung area were most seriously affected, with only 11 in operation.
In Taipei, the Great Taipei Gas Corp received several hundreds of reports of gas leakages yester-day. The company sent a 25-member team to the area around the Tung Hsing Building in Sungshan District, which collapsed yesterday morning, to stop gas leakages. Unable to reach the building's gas pipes, the team used two backhoes to stop the pipes on Pateh Road and Fuyuan Street.
The domestically designed Teng Yun 2 drone passed development milestones over the weekend, flying for more than 10 hours straight and circling Taiwan’s air defense identification zone (ADIZ), in the longest flight of an indigenous uncrewed combat aerial vehicle. Developed by the Chungshan Institute of Science and Technology, the Teng Yun 2, or “Cloud Rider” (騰雲二型), recorded its longest flight yet over the weekend, after a three-hour test flight last month, followed by five and seven-hour stretches in the air. The Teng Yun 2 No. 1812 departed from Chiashan Air Base in Hualien County at 6:46pm on Saturday and flew on a
OVER THE HUMP: In a seven-day period ending on Wednesday, the nation reported 366,628 new cases, down 19 percent from the 451,358 reported in the previous week The nation might further open up to more arrivals in the next two months, the Central Epidemic Command Center (CECC) said yesterday, as it reported 48,283 new local COVID-19 cases, down from more than 50,000 in the previous few days. Taiwan on Wednesday last week introduced a plan to allow up to 25,000 arrivals per week as part of efforts to gradually reopen borders, which includes reducing mandatory quarantines for inbound travelers from seven to three days, followed by four days in “self-initiated epidemic prevention.” The quota covers inbound Taiwanese arrivals, businesspeople and migrant workers. Former vice president Chen Chien-jen (陳建仁) yesterday said
The Ministry of National Defense yesterday said it is monitoring Chinese People’s Liberation Army (PLA) Navy ship movements near Taiwan, after the Japanese Ministry of Defense disclosed that Chinese vessels made a rare voyage between Yilan County and Japan’s Yonaguni. The Japanese ministry on Wednesday said that two Chinese navy ships on Tuesday diverted from their usual route of entering the Pacific Ocean via the Miyako Strait and for the first time traveled there between Yilan and Yonaguni. The Japan Self-Defense Forces said that it picked up the presence of China’s Type-056A Jiangdao-class corvette 220km north of Yonaguni at 9am on Tuesday. The
A slew of new measures are to take effect on Friday, including nationwide bring-your-own-cup discounts. The new rule requires chain beverage shops to offer discounts of at least NT$5 (US$0.17) to customers who bring their own cups, the Environmental Protection Agency (EPA) has said. The policy would apply to more than 50,000 chain retail locations, including beverage shops, convenience stores, fast-food restaurants and supermarkets. It aims to cut down on waste from single-use plastic cups, more than 2.2 billion of which were used in Taiwan in 2020, the agency said. For convenience, the EPA said it has asked retailers to display signs stating how
