Run of earthquakes along east coast normal: weather bureau

Taipei, Oct. 19 (CNA) A string of earthquakes that hit Taiwan's eastern coast Monday represented a normal release of energy, the Central Weather Bureau (CWB) said that day. Eight temblors struck the area between midnight and 3 p.m. Monday, ranging in magnitude from 3.5 to 5.2 on the Richter scale, according to bureau data. But there is no need to panic, it said, explaining that most of the tremors were energy releases from friction between the Philippine and the Eurasian tectonic plates, which is a common cause of earthquakes in Taiwan. While also normal, the biggest temblor among them -- a magnitude 5.2 earthquake that jolted Yilan in northeastern Taiwan at 10:17 a.m. -- took place because of an expansion of the Okinawa Trough, according to the bureau. Taiwan usually sees 30 earthquakes measuring 5.0 or higher per year, and Monday's temblor brought the number of quakes under that category this year to 21, according to CWB data. Five of those exceeded magnitude 6.0, with the strongest a magnitude 6.4 quake that occurred April 20 at sea about 80 kilometers off the coast of Hualien County. (By Lee Hsin-Yin)
