The strongest earthquake in 25 years rattled Taiwan and triggered tsunami warnings throughout the region.

An earthquake rocked the entire island of Taiwan early Wednesday, collapsing buildings in a southern city and sparking a brief tsunami warning for southern Japanese islands.

Video and images on social media showed buildings shaken off their foundations. A five-story building in lightly populated Hualien appeared heavily damaged, collapsing its first floor and leaving the rest leaning at a 45-degree angle.

In the capital, Taipei, tiles fell from older buildings and within some newer office complexes.
