Earthquake, tsunami hit Pacific Islands: Why was it barely noticeable?

An earthquake with a magnitude of 7.2 hit the Pacific Ocean between the island nations Vanuatu and New Caledonia on Friday. An initial tsunami warning was issued for those islands and Fiji, but it was later rescinded by the Pacific Tsunami Warning Center because the resulting tsunami only brought normal sized waves curling toward the shore.
