Taipei, July 23 (CNA) A magnitude-4.2 earthquake jolted northeastern Taiwan early Monday, but there were no reports of casualties or damage, according to the Central Weather Bureau.
The tremor's epicenter was located at sea 43 kilometers southeast of Yilan County Hall at a depth of 10.8 km, the bureau's Seismology Center said.
Yilan's Nanao Township recorded the strongest reading at an intensity of 4, the center said.
According to seismologists, earthquakes here mainly reflect the island's geography because Taiwan is located in a region where the Philippine Sea Plate borders the Eurasian Plate.
Dozens of earthquakes and aftershocks, including a magnitude-6.5 one,were recorded in various parts of Taiwan in June, but none of them caused casualties or major damage as their epicenters were all located deep at seas.
