The Central Weather Bureau reported 22 quakes over two hours starting at 6:52 a.m.
The first was the largest with a magnitude of 5.2 and struck at a relatively shallow depth of 5.9 kilometers (3.7 miles). The others ranged from magnitude 3.0 to 5.0.
A photo posted on the Taiwan Apple Daily news website showed the remains of a second floor wall above a storefront that had fallen to the street and crumbled. The earthquakes were in Hualien County around the midpoint of the island’s east coast.
