Aftershocks expected after earthquake, bureau says
Staff writer, with CNA
Taiwan could experience aftershocks of magnitude 4 or higher over the next week, in the wake of a magnitude 6.7 earthquake on Thursday night, which jolted northern and northeastern parts of the country, the Central Weather Bureau said.
The temblor, which struck at 9:19pm off Yilan County, occurred in a subduction zone comprising the Eurasian Plate and the Philippine Sea plate, Seismological Center Director Chen Kuo-chang (陳國昌) said.
While quakes in subduction zones usually involve a quick release of energy, thereby reducing the risk of major aftershocks, tremors of magnitude 4 or higher remain a possibility over the next week, Chen said yesterday.
