The National Land Management Agency doled out subsidies to 70 projects to strengthen buildings against earthquakes in nine administrative regions from January to last month, it said on Tuesday.
The quake-proofing projects consisted of 20 in Taipei, 16 in New Taipei City, 10 in Taitung County, eight in Tainan, six in Pingtung County, four in Hualien County, three in Yilan County, two in Yunlin County and one in Taichung, including completed and ongoing projects, the agency added.
The three completed projects in Hualien survived the April 3 earthquake, which measured 7.2 on the Richter scale, with no signs of structural damage, the agency said.

Taiwan revamped its building code after the catastrophic 921 Earthquake, which resulted in a large improvement in safety standards for buildings across the nation, Taiwan Structural Engineers Association executive director Chiang Shih-hsuang (江世雄) said.
The 921 quake, which occurred on Sept. 21, 1999, measured 7.3 on the Richter scale and left 2,456 people dead and 10,718 injured, and destroyed 53,661 houses.
Despite the nation’s best efforts, the earthquake resistance of many concrete structures 30 years or older remains less than ideal, while structures nearing the end of their 50-year service life need to be torn down, Chiang said.
Reinforced brick, wood and stone construction of all kinds, many of which are older, need to be comprehensively re-examined for their ability to withstand quakes, he said.
An example of a common unsafe building design is structures at street corners with ground-level shop fronts on both sides with a glass facade, Chiang said.
Buildings with excessive volumes of empty internal space, such as big lobbies with tall ceilings, are another example of popular architectural styles that are highly risky, he added.
These types of buildings suffer from a lack of structural walls and pillars relative to their size and can be found all over Taiwan, Chiang said.
About 9.19 million properties are registered as residential buildings, of which 65.53 percent are made of concrete and 18.4 percent are made of reinforced brick, government data showed.
Older buildings in Taiwan often feature ground levels designed to yield a maximum of floor space and emphasize openness and lighting, said Andy Huang (黃舒衛), director of Landlord Representation Services at Colliers International Taiwan.
These practices, in many cases, violate safety codes, resulting in structures that must be overhauled to comply with the more rigorously written and enforced modern safety laws, Huang said.
As outdated buildings are the least likely to attract tenants, landlords owning unsafe properties often lack money to refurbish them, creating a vicious cycle, Huang added.
The Coast Guard Administration (CGA) and Chunghwa Telecom yesterday confirmed that an international undersea cable near Keelung Harbor had been cut by a Chinese ship, the Shunxin-39, a freighter registered in Cameroon. Chunghwa Telecom said the cable had its own backup equipment, and the incident would not affect telecommunications within Taiwan. The CGA said it dispatched a ship under its first fleet after receiving word of the incident and located the Shunxin-39 7 nautical miles (13km) north of Yehliu (野柳) at about 4:40pm on Friday. The CGA demanded that the Shunxin-39 return to seas closer to Keelung Harbor for investigation over the
National Kaohsiung University of Science and Technology (NKUST) yesterday promised it would increase oversight of use of Chinese in course materials, following a social media outcry over instances of simplified Chinese characters being used, including in a final exam. People on Threads wrote that simplified Chinese characters were used on a final exam and in a textbook for a translation course at the university, while the business card of a professor bore the words: “Taiwan Province, China.” Photographs of the exam, the textbook and the business card were posted with the comments. NKUST said that other members of the faculty did not see
An apartment building in New Taipei City’s Sanchong District (三重) collapsed last night after a nearby construction project earlier in the day allegedly caused it to tilt. Shortly after work began at 9am on an ongoing excavation of a construction site on Liuzhang Street (六張街), two neighboring apartment buildings tilted and cracked, leading to exterior tiles peeling off, city officials said. The fire department then dispatched personnel to help evacuate 22 residents from nine households. After the incident, the city government first filled the building at No. 190, which appeared to be more badly affected, with water to stabilize the
EARTHQUAKE: Taipei and New Taipei City accused a construction company of ignoring the Circular MRT’s original design, causing sections to shift by up to 92cm The Taipei and New Taipei City governments yesterday said they would seek NT$1.93 billion (US$58.6 million) in compensation from the company responsible for building the Circular MRT Line, following damage sustained during an earthquake in April last year that had shuttered a section for months. BES Engineering Corp, a listed company under Core Pacific Group, was accused of ignoring the original design when constructing the MRT line, resulting in negative shear strength resistance and causing sections of the rail line between Jhonghe (中和) and Banciao (板橋) districts to shift by up to 92cm during the April 3 earthquake.
