A moderate quake struck the sea off Taiwan's east coast late Sunday morning, with no damage or disruption reported so far.

• The magnitude 5.1 quake hit at 11:40 a.m., centered in the ocean about 42 kilometers southeast of Yilan County.
• It was shallow-to-moderate in depth, roughly 28 kilometers down.
• Shaking was strongest in Yilan and Hualien counties, with lighter shaking felt in Taipei and New Taipei.
• Taipei's metro system ran normally, with no impact on service.

Outlook: Aftershocks are possible, but a quake of this size in the ocean is unlikely to cause serious damage on land.
