A powerful 7.1 magnitude earthquake hit a remote part of eastern Indonesia on Saturday, but there were no immediate reports of damage or injuries, an official said.

The temblor struck about 75 km underground in Papua province, according to U.S. Geological Survey. It occurred in a mountainous area, about 56 km north-east of Tolikara, said Ali Imran, an official at the Meteorology and Geophysics Agency in Jakarta. There was no tsunami warning issued due to its location, he added.

The quake was felt across many parts of Papua, including the capital Jayapura and the copper town of Timika and Wamena, another town in the mountains, he said. Residents ran from their houses in panic, and many remained outside fearing aftershocks.

Indonesia is prone to seismic upheaval due to its location on the Pacific “Ring of Fire,” an arc of volcanoes and fault lines encircling the Pacific Basin.
