Taiwan remained unaffected from leakage of the radioactive material following an explosion that took place Saturday at one of the reactors at the Fukushima Daiichi plant of Japan, said an official with Taiwan atomic affairs agency Sunday.

The official insisted that around the Fukushima plant area, the wind was blowing from the west to the east, but Taiwan is located to the southwest of Japan.

"I believe Taiwan will therefore not be affected by the leakage of the radioactive material from one of the reactors with the Japanese nuclear power plant," said the official.

He said that data shown by all of the 30 radiation monitoring centers across the Taiwan Island had proven normal thus far.

He pledged that they would continue to step up monitoring of the environment against the radiation and pay close attention to any change therein to ensure the safety of residents in Taiwan.

A massive 9.0-magnitude earthquake jolted off the east coast of Japan's main Honshu Island at 1:46 p.m. Beijing Time Friday, triggering a tsunami and causing deaths and those missing in the thousands.

While addressing a symposium on coping with major disasters held on Sunday, Taiwan leader Ma Ying-jeou said an array of disasters happened in the wake of Friday's powerful quake off the northeastern coast of Japan.

Ma reiterated the significance of reexamining Taiwan's major disaster response mechanism in a bid to get Taiwan well prepared in case of any.
