The limited aftershocks contrast with last year’s major earthquake in Hualien County, as Saturday’s earthquake occurred at a greater depth in a subduction zone. Saturday’s earthquake struck at 11:05pm, with its hypocenter about 32.3km east of Yilan County Hall, at a depth of 72.8km. A map with Taiwan’s seven-color earthquake intensity scale shows that an intensity level of 4 was recorded in several administrative regions after a magnitude 7.0 earthquake that struck off Yilan County at 11:05pm on Saturday. A graphic shows the peak ground acceleration of a magnitude 7.0 earthquake that struck off Yilan County at 11:05pm on Saturday. The Hualien quake was a shallow fault-zone event, occurring at 15.5km deep, while Saturday’s Yilan quake was a subduction-zone earthquake caused by the Philippine Sea Plate subducting northward beneath the Eurasian Plate, Wu said.
