Seismologists say a 7.1 magnitude earthquake has struck about 100 kilometers south of the coast of Taiwan.

Japanese seismologists have issued a tsunami warning for the region, saying a one-meter-tall tsunami is now heading for the Philippines.

Taiwanese scientists say the earthquake was followed by a magnitude 6.4 aftershock that struck off of southwestern Taiwan.

There have been no immediate reports of damage or casualties.
