Taipei, June 15 (CNA) More moderate to strong aftershocks can be expected in eastern Taiwan over the next two weeks in the wake of a magnitude 5.4 earthquake in that area early Friday, the Central Weather Bureau (CWB) warned.
As of 11 a.m. Friday, a total of 58 aftershocks had been recorded in Hualien County after the main earthquake that occurred at 0:15 a.m., the bureau said.
The quake's epicenter was located at sea 31.5 kilometers south of Hualien County Hall at a depth of 10 km, the bureau said. The tremor was felt at an intensity of 6 in the county's coastal area of Jichi, it said.
Since the earthquake was strong and at a shallow depth, it is likely that aftershocks of between magnitude 4 and 5 would continue in the next two weeks, said Kuo Kai-wen, director of the bureau's seismology center.
However, Kuo urged the public not to panic over the frequent aftershocks, saying they are just a normal release of energy.
"The number of aftershocks remains in a reasonable range," Kuo said. "There is no need to worry."
Eastern Taiwan's location between two tectonic plates --the Philippine Sea Plate and the Pacific Plate -- makes it especiallyprone to earthquakes, he said.
When the magnitude 7.3 earthquake struck central Taiwan on Sept. 21, 1999, about 1,000 aftershocks occurred the same day, he said.
