Taitung could see more moderate quakes in coming week: CWB
Taipei, Sept. 29 (CNA) More earthquakes measuring 4 or above on the Richter scale are likely in Taitung over the coming week following a series of temblors there Tuesday, the Central Weather Bureau (CWB) said.
A total of nine earthquakes were recorded from 3 a.m. to 2 p.m. Tuesday in Taitung, southeastern Taiwan, with their epicenters located at sea 40-50 kilometers south of Taitung County Hall, bureau data showed.
The temblors ranged from 3.5-5.3 in magnitude and were at a depth of 9-14 km, according to the CWB.
The magnitude 5.3 temblor occurred at 4:50 a.m., and was felt across central and southern Taiwan. Its intensity, which gauges the actual effect of a quake, was highest in Taitung, where it measured 4 on Taiwan's 7-tier intensity scale, the bureau said.
The earthquakes were likely caused by seismic activity in the Manila Trench between Taiwan and the Philippines, said Chen Kuo-chang (陳國昌), director of the CWB Seismological Center.
Chen said similar clusters of quakes usually take place in Taitung every two to six years, but most are relatively small.
A total of 24 earthquakes measuring 4-5 in magnitude have been recorded in the area since 2000, and another two measuring over 5, both of which took place Tuesday, he said.
