SYDNEY (CBS/AP) — A tsunami threat message was canceled Friday evening (Saturday local time) after a strong earthquake struck the Santa Cruz Islands in the South Pacific. No damage or casualties were reported.

The Pacific Tsunami Warning Center said the quake measured 6.9, down from a preliminary estimate of 7.5. It hit at a depth of 33 kilometers (20 miles) and was centered undersea 75 kilometers (47 miles) northwest of Lata in the western Solomon Islands, where the Santa Cruz Islands are located.

The Solomons comprise more than 200 islands with a population of about 552,000 people. The islands lie on the “Ring of Fire” – an arc that stretches around the Pacific rim and where about 90 percent of the world’s quakes occur.

A magnitude 8 quake near Lata in February 2013 generated a tsunami up to 1.5 metters (5 feet) high that damaged dozens of homes and left several people dead on the western side of the Santa Cruz.
