Indonesia was struck by a 7.6 magnitude earthquake on Tuesday off the Tanimbar islands, prompting panicked residents in the area to flee their homes, although a tsunami warning was lifted after three hours and initial reports indicated limited damage.
The Tanimbar islands are a group of about 30 islands in eastern Indonesia's Maluku province.
At least four aftershocks were reported after the powerful quake that was also felt in some parts of northern Australia.
Indonesia disaster agency officials said that at least 15 homes and two school buildings were damaged, with one person injured, after the tremor was felt strongly for 3-5 seconds.
The quake, locally measured as magnitude 7.5, struck at a depth of 130 km (80.78 miles) at 2:47 am local time (1747 GMT on Monday), the country's geophysics agency BMKG said. The tsunami warning was lifted at 5:43 am
"Based on our observation of four tide gauges around the earthquake's epicentre … there was no anomaly detected or no significant changes of sea level," BMKG head Dwikorita Karnawati told a news conference, advising people who lived near the coast to continue with their activities.
The European Mediterranean Seismological Centre (EMSC) recorded the magnitude of the quake as 7.6, after initially reporting it as 7.7. The US Geological Survey also pegged it as a 7.6 magnitude.
There were four aftershocks with the strongest recorded at 5.5 magnitude, BMKG said.
