Just two weeks after one of the biggest earthquake in Taiwan, on Monday night more than 80 earthquakes, the strongest of 6.3 magnitude, struck Taiwan's east coast.

Some of the earthquake caused shaking of buildings in the capital Taipei, the island's weather administration said.

Largely rural and sparsely populated Hualien was hit by a 7.2 magnitude earthquake on April 3 that killed at least 14 people, and there have been more than 1,000 aftershocks since.

Buildings across large parts of northern, eastern and western Taiwan, including in the capital, Taipei, swayed throughout the night, with the largest quake measuring a 6.3 magnitude. All were very shallow. Taiwan's Central Weather Administration said the spate of earthquakes starting Monday afternoon - which it put at about 180 - were aftershocks from the large April 3 quake.

The world's largest contact chipmaker, Taiwan Semiconductor Manufacturing Co, whose factories are on the island's western coast, said some staff at a small number of factories were evacuated, but facility and safety systems were functioning normally and all personnel were safe.

In 1999, a magnitude 7.7 earthquake in Taiwan killed 2,400 people.
