Taipei, Nov. 11 (CNA) Nantou and Yunlin Counties have been jolted five times by earthquakes on Saturday evening, each measuring above 4 on the Richter scale, according to the Central Weather Bureau (CWB).

The first quake struck at 7:14 p.m. with a magnitude of 4.4 and was felt across parts of Chiayi and Changhua Counties.

The epicenter of the first earthquake was about 28.8 kilometers south of Nantou County Hall at a depth of 16.8 km, according to the CWB's Seismology Center.

About one hour later at 8:13 p.m., a second quake rocked Gukeng Township in Yunlin County with a magnitude of 4.2, which was felt in the central Taiwanese county the highest intensity of 4 on Taiwan's 7-tiered intensity scale. It recorded an intensity of 3.0 in Mingjian Township in Nantou County, which borders Yunlin.

Nine minutes later, the third temblor struck, centered 29.1 km south of Nantou County Hall at a depth of 17.2 km, creating widespread tremors that were felt across central and southern Taiwan.
