The National Center for High-Performance Computing (NCHC) and Academia Sinica have developed an artificial intelligence (AI) model that could help researchers predict earthquakes one day in advance.
The model could predict earthquakes based on precursors to tectonic activity, researchers said.
The research team, led by Academia Sinica researcher Lee Lou-chuang (李羅權) and NCHC associate researcher Tsai Tsung-che (蔡宗哲), developed an AI model using total electron content (TEC) data and the Taiwania 2 supercomputer.

The model could predict a magnitude 6 or higher earthquake one day in advance by analyzing data from the previous 30 days, they said.
Past studies also found that atmospheric TEC within a 50km radius of the epicenter of an earthquake show signs of change prior to a large earthquake, the Central Weather Bureau’s Seismological Center said, adding that TEC above Taiwan proper was low just before the 1999 Jiji earthquake.
National Taiwan University researcher Jhuang, Hau-Kun (莊皓琨), who was also on the research team, on Saturday said the team analyzed TEC data from Europe spanning 2003 to 2014.
“By filtering out certain information such as the disturbance storm time index, sunspot data and the solar radiation index, we were able to accurately determine hourly TEC changes,” he said.
The team also used data from 19 cases of TEC changes in which an earthquake did not occur to improve the accuracy of the AI model, he said.
“The system can now predict when a magnitude 6 or higher earthquake will occur, but we are still limited by the resolution of ionospheric data, and we cannot say for sure where the epicenter will be,” he said.
“We also have to work with a data transmission delay of five days or so, since our global ionospheric data are provided by Europe,” he added.
The team also found that the concentration of radon levels in the ground changes before a major earthquake, Academia Sinica researcher Fu Ching-chou (傅慶州) said, adding that the level of change increases with the earthquake’s intensity and proximity to the epicenter.
“We hope that through all of these factors we will be able to determine more accurately when a major quake will occur, so that we can notify people and ensure their safety,” he said.
The team’s findings have been published by the journal Earth and Space Science.
A relatively large earthquake may strike within the next two weeks, following a magnitude 5.2 temblor that shook Taitung County this morning, the Central Weather Administration (CWA) said. An earthquake struck at 8:18am today 10.2km west of Taitung County Hall in Taitung City at a relatively shallow depth of 6.5km, CWA data showed. The largest intensity of 4 was felt in Taitung and Pingtung counties, which received an alert notice, while areas north of Taichung did not feel any shaking, the CWA said. The earthquake was the result of the collision between the Philippine Plate and the Eurasian Plate, the agency said, adding
Snow fell in the mountainous areas of northern, central and eastern Taiwan in the early hours of yesterday, as cold air currents moved south. In the northern municipality of Taoyuan, snow started falling at about 6am in Fusing District (復興), district head Su Tso-hsi (蘇佐璽) said. By 10am, Lalashan National Forest Recreation Area, as well as Hualing (華陵), Sanguang (三光) and Gaoyi (高義) boroughs had seen snowfall, Su said. In central Taiwan, Shei-Pa National Park in Miaoli County and Hehuanshan National Forest Recreation Area in Nantou County saw snowfall of 5cm and 6cm respectively, by 10am, staff at the parks said. It began snowing
The 2025 Kaohsiung Wonderland–Winter Amusement Park event has teamed up with the Japanese manga series Chiikawa this year for its opening at Love River Bay yesterday, attracting more than 10,000 visitors, the city government said. Following the success of the “2024 Kaohsiung Wonderland” collaboration with a giant inflatable yellow duck installation designed by Dutch artist Florentijn Hofman, this year the Kaohsiung Tourism Bureau collaborated with Chiikawa by Japanese illustrator Nagano to present two giant inflatable characters. Two inflatable floats — the main character, Chiikwa, a white bear-like creature with round ears, and Hachiware, a white cat with a blue-tipped tail
HOLIDAY EXERCISE: National forest recreation areas from north to south offer travelers a wide choice of sights to connect with nature and enjoy its benefits Hiking is a good way to improve one’s health, the Forestry and Nature Conservation Agency said, as it released a list of national forest recreation areas that travelers can visit during the Lunar New Year holiday. Taking a green shower of phytoncides in the woods could boost one’s immunity system and metabolism, agency Director-General Lin Hwa-ching (林華慶) cited a Japanese study as saying. For people visiting northern Taiwan, Lin recommended the Dongyanshan National Forest Recreation Area in Taoyuan’s Fusing District (復興). Once an important plantation in the north, Dongyanshan (東眼山) has a number of historic monuments, he said. The area is broadly covered by
