Magnitude 6 earthquake strikes off the east coastSTAYING ALERT: Some people reported receiving as many as a dozen earthquake warning messages, which the Central Weather Bureau said was due to an errorBy Shelley Shan / Staff reporterA magnitude 6.1 earthquake yesterday struck off Taiwan’s east coast at 1:36am, the Central Weather Bureau said, adding that aftershocks of magnitude 4 or higher could occur in the next three days. However, the center has already recorded five magnitude 5 or larger earthquakes since last month, including yesterday’s, he said. Last year, there were 25 magnitude 5 to 6 earthquakes, whereas there were only four earthquakes larger than magnitude 6, Chen said. “The earthquake’s epicenter was far from Taiwan’s northeast coast and was more than 110km deep, which presented a challenge to the early warning system,” he said. To prevent the system from repeating the same warning message, the bureau has begun to improve the automatic detection modules in the earthquake early warning system, Cheng said.
