A small earthquake struck off Taiwan's east coast early Thursday morning, with no damage reported and shaking barely felt.

• The quake measured 4.2 in magnitude and hit at 3:32 a.m. off the coast near Hualien County.
• It was fairly shallow, at a depth of about 25 kilometers under the seabed.
• Shaking reached only the lowest level on Taiwan's intensity scale, meaning most people would not have noticed it.
• Light tremors were picked up in Hualien, Yilan, Nantou, Taichung and as far north as New Taipei City.

Outlook: No damage or disruption is expected, though the area off eastern Taiwan stays seismically busy and more small quakes are likely.
