Taiwan hit by dozens of strong aftershocks from deadly quake

TAIPEI - Taiwan was shaken by dozens of earthquakes overnight and into Tuesday that left buildings swaying, with the government saying they were aftershocks from a huge deadly quake that hit the island more than two weeks ago.

The strongest, which the US Geological Survey measured at magnitude 6.1, hit around 2.30am followed minutes later by a 6.0 tremor.

Taipei's Central Weather Administration put them at 6.0 and 6.3, respectively.

Authorities said there were no casualties reported so far, but the non-stop shaking meant a restless night even for those in the capital Taipei about 150 kilometres north, where walls and glass panels rattled in swaying homes.

Around 8am, a 5.8-magnitude tremor shook the capital as commuters made their way to work.

The series of quakes started Monday around 5pm, originating from Hualien on the central east coast of Taiwan.

The mountainous county was the epicentre of a magnitude-7.4 quake that hit April 3, which Taiwan said was the "strongest in 25 years", triggering landslides that blocked roads and severely damaged buildings around the main Hualien city.

At least 17 people were killed, with the latest body found in a quarry on April 13.

In Hualien on Tuesday, a hotel building that was previously damaged started tilting at an angle overnight after the quakes, according to footage obtained by AFP.

Hualien county government announced that schools and offices would be closed Tuesday due to the continuous aftershocks.
