Taiwan Hit by 7.4 Quake

A major 7.4-magnitude earthquake hit Taiwan's east, prompting tsunami warnings for the self-ruled island as well as parts of southern Japan and the Philippines.

The United States Geological Survey (USGS) put the epicenter 18 kilometers south of Taiwan's Hualien City, at a depth of 34.8 km.

Japan's Meteorological Agency issued a warning for tsunami waves as high as three meters for remote Japanese islands in the region, including Miyakojima island.

In Taiwan, authorities issued a tsunami warning via text message "to remind people in coastal areas to be vigilant and take strict precautions and pay attention to the dangers caused by sudden surges in waves".

The initial earthquake was felt across Taiwan, with reporters from the southern Pingtung county to the north in Taipei reporting strong shaking sensations.

The aftershocks -- which included a 6.5-magnitude earthquake near Hualien according to Taipei's weather agency -- were also felt in Taipei.

In the capital, the metro briefly stopped running but appeared to have resumed within an hour, while residents received warnings from their local borough chiefs to check for any gas leaks.

Officials said the earthquake was the strongest felt on the island in decades.

"The earthquake is close to land and it's shallow. It's felt all over Taiwan and offshore islands," said Wu Chien-fu, director of Taipei's Central Weather Administration's Seismology Center.

"It's the strongest in 25 years since the 1999 earthquake," he told reporters.

A 7.6-magnitude quake hit Taiwan in September 1999, killing around 2,400 people in the deadliest natural disaster in the island's history.

Wu warned that authorities are not ruling out that "there will be earthquakes with magnitudes of 6.5 to 7 in three days which will be relatively close to the land".
