TAIPEI (AFP) - An earthquake with a magnitude of 6.6 struck off the coast of Taiwan early Wednesday (March 23), the US Geological Survey said.

There were no immediate reports of fatalities or injuries, or major damage.

The USGS said the quake, which it downgraded from an earlier estimate of magnitude 6.9, had a depth of 10km and hit 70km south of Hualien City.

An AFP reporter felt her building shaking a few minutes after 1.40am in Taipei’s Zhongshan district. Government-issued alerts sent people’s mobile phones blaring.

Taiwan’s Central Weather Bureau said an initial quake of 5.4-magnitude at occurred at 1.06am.

It was followed by the big one of magnitude 6.6 at 1.41am, and two minutes later came a 6.1-magnitude aftershock, the bureau reported.

Taiwan is regularly hit by earthquakes as the island lies near the junction of two tectonic plates.

Taiwan does not issue tsunami warnings unless a quake is more than magnitude 7.0.

Some earthquakes of 6.0 or more can prove deadly, although much depends on where the quake strikes and at what depth.

But the USGS gave a “green” ranking to the threat posed by the latest quake, predicting a low likelihood of either casualties or damage.

The last time Taiwan experienced a quake of a similar magnitude was in January, when a 6.2 quake hit its east coast. But there were no reports of widespread damage or injuries.

A 6.5-magnitude quake struck northeastern Yilan in October 2021 with minimal damage.

But a 6.4-magnitude quake in 2018 hit Hualien, a scenic tourist hotspot, which left 17 people death and 300 injured.
