Tainan experienced four earthquakes on Saturday, with the largest one reaching magnitude 5.2. No deaths or injuries were reported.
A magnitude 4 earthquake struck at 5:06am in the city’s Sinshih District (新市).
At 8:07pm, a magnitude 4.2 earthquake was recorded, with its epicenter in the city’s Dongshan District (東山), which was followed by magnitude 5.2 and magnitude 4.7 earthquakes that happened at 11:03pm and 11:05pm in the district, the Central Weather Bureau’s Seismology Center data showed.
The magnitude 5.2 earthquake was the main shock, with the magnitude 4.2 and the magnitude 4.7 earthquakes being the foreshock and aftershock, the center said, adding that the epicenters of the three earthquakes were close.
The hypocenters of the four earthquakes were less than 20km underground, the center said.
The earthquake in Sinshih delayed high-speed rail services, as it forced a train to temporarily stop between Chiayi and Tainan.
Four trains operated by the Taiwan Railways Administration were also delayed, as train drivers are required to reduce speed in the event of an earthquake.
Workers at Taiwan Semiconductor Manufacturing Co’s factory in Tainan were at one point asked to evacuate, the Southern Taiwan Science Park (南部科學工業園區) administration said, adding that the company’s facilities did not sustain any damage.
Seismology Center specialist Wu Chien-wen (吳健文) yesterday said that the three earthquakes in Dongshan occurred due to the release of energy accumulated at a geologically fractured zone, which was triggered by the Philippine Sea Plate and Eurasian Plate squeezing against each other.
However, they were not related to the earthquake in Sinshih, Wu said.
Residents of Tainan and Chiayi County should be careful, as aftershocks of magnitude 4 or higher are expected this week, he said.
Aside from Saturday’s magnitude 5.2 earthquake, there were nine other earthquakes exceeding magnitude 5 that happened within a 10km radius of the epicenters of the Dongshan earthquakes over the past 100 years, bureau data showed.
The last time an earthquake exceeding magnitude 5 happened in the area was in November 1995.
The largest earthquake recorded in the area was a magnitude 6.2 earthquake on Dec. 22, 1930.
As the hypocenters of the earthquakes on Saturday night were near the Lijia Fault, Wu said the bureau would investigate if geological activity along the fault might be related to the earthquakes.
FEW REMAIN: Conservationists tried to stop the demolition, but to no avail, and the owner cannot be fined, as the structure was not listed as a historical building One of the few remaining Japanese colonial-era granaries in Taiwan was dismantled by its owner on Friday, prompting outrage from conservationists. The granary, which was at No. 16, Lane 11, Hangzhou S Rd Sec 1 in Taipei, belonged to Taiwan Takushoku Corp during the colonial era, conservationist Chang Wan-lin (張琬琳) said, adding that she and others had been collecting information to reapply to have the building protected as a historical structure. During the colonial era, the granary served the area from Monga (艋舺) to what is now Songshan District (松山) in the north, she said. “Back then the eastern part
SEEING THE POSITIVE: A majority of respondents in Taiwan said that they favored Trump because they think Taiwan-US ties would improve with him Among eight Asia-Pacific countries and regions, only Taiwan prefers US President Donald Trump over his challenger, former US vice president Joe Biden, in the upcoming US presidential election, a survey released on Thursday showed. According to the poll published by UK-based market research firm YouGov, 42 percent of Taiwanese favor Trump in the Nov. 3 election, while 30 percent back Biden and 28 percent have no opinion. In contrast, respondents in Malaysia favor Biden over Trump 62 percent to 9 percent, and in Singapore by 66 percent to 12 percent, the survey showed. Biden also led Trump in Australia (60 percent to 21
TROUBLEMAKER: The missiles, capable of striking up to 2,000km away, would likely be used to deter other nations from coming to Taiwan’s aid, a legislator said The Chinese People’s Liberation Army (PLA) has reportedly deployed advanced hypersonic missiles along China’s southeast coast, which Taiwan’s missile defense system might have difficulty intercepting, an analyst said yesterday. Citing an unnamed military source, the South China Morning Post said that the missile bases on the coasts of China’s Fujian and Zhejiang provinces have been upgraded and are stocked with DF-17 missiles, equipped with hypersonic glide vehicles. “The DF-17 hypersonic missile will gradually replace the old DF-11s and DF-15s that were deployed in the southeast region for decades,” said the source, who requested anonymity because of the sensitivity of the topic. “The
AIR CONTROL INCIDENT: The Hong Kong side said it ‘cannot accept this aircraft,’ ordering it to ascend to an unsafe altitude and forcing it to return to Kaohsiung The Civil Aeronautics Administration (CAA) on Friday disclosed a full transcript of the communications between Taiwanese and Hong Kong air traffic controllers, rebutting the latter’s claim that a Taiwanese plane had voluntarily abandoned its flight path. Hong Kong denied permission for the plane to proceed to the disputed Pratas Islands (Dongsha Islands, 東沙群島), which are claimed by both Taiwan and China, the CAA said. The incident happened on Thursday when a civil aircraft chartered by the military was advised by Hong Kong air traffic controllers to not enter the airspace over a group of islands in the South China Sea
