Powerful 7.7 magnitude quake hits off Indonesian coast

Initial reports indicated there was damage to homes and public facilities

A powerful magnitude 7.7 earthquake struck off the coast of Indonesia early Saturday, damaging buildings and homes, and triggering a tsunami warning. Authorities urged people on affected coastlines to move to higher ground.

The U.S Geological Survey said the quake hit Indonesia's Flores region with a depth of 10 kilometers at 5:58 a.m. Indonesia time. Its epicentre was 68 kilometres north-northwest of the city of Ende in East Nusa Tenggara province.

The initial quake was followed by several aftershocks. There were no immediate reports of casualties.

Indonesia's Meteorology, Climatology and Geophysics Agency issued a tsunami warning for part of East Nusa Tenggara, West Nusa Tenggara, South Sulawesi and Southeast Sulawesi provinces, and urged residents to stay away from beaches and riverbanks.

The agency located the shallow undersea quake near Flores island.

Residents along affected coastlines were advised to move to higher ground as officials are closely monitoring coastal tide gauges for any changes.

Yohanna Embu, a resident of Sikka, a regency within East Nusa Tenggara province, said a number of buildings were damaged by the strong shaking and panicked people ran to higher ground.

"Many buildings here were damaged ... I saw that the waiting room at the port terminal in Maumere had collapsed," she said.

Students at St. Peter Major Seminary in Sikka who were attending morning Mass fled in panic when the roof of an assembly hall collapsed, said the Rev. Guidelbertus Tanga, rector of the seminary, which is known locally as Ritapiret Seminary on the predominantly Catholic island of Flores.

"Our students and nuns ran out in panic beneath a collapsing roof," Tanga said, "At least one priest suffered a broken leg after jumping from the second floor of a building during the quake."

Indonesia, a vast archipelago of more than 17,000 islands, is prone to earthquakes and volcanic activity because of its location on the "Ring of Fire," an arc of volcanoes and fault lines in the Pacific Basin.

In December of 1992, a magnitude 7 earthquake caused a tsunami that killed about 2,500 people on the southeastern island of Flores, part of a group of islands in the eastern half of Indonesia.
