Earthquake In Indonesia: The USGS said the quake struck at a depth of 76 kilometres (47 miles) in the Flores Sea at 0320 GMT.
Jakarta: A 7.3-magnitude earthquake struck eastern Indonesia on Tuesday, the US Geological Survey said, triggering panic but no deaths or major damage were reported.
The epicenter of the quake was in the Flores Sea, north of East Nusa Tenggara province, where the quake late in the night (0320 GMT) caused panic.
"I was in the field. People ran in panic. I'm still... scared," said Nuraini, a resident of Adonara Island in East Flores Regency.
No significant damage or fatalities were immediately reported, but Indonesian officials urged caution with more than a dozen small aftershocks detected.
National Disaster Agency spokesman Abdul Muhari said in a statement that one person was injured in Manggarai in East Nusa Tenggara and a school building on Selyar Island was damaged.
He said that the impact of the earthquake is still being assessed.
The intensity of the tremors triggered panic in many areas, with videos from some towns and villages shared on social media showing people running outside, some holding small children.
Traffic was blocked on the roads as vehicles tried to move to safer places.
The USGS placed the quake's epicenter at a depth of 18.5 kilometers (11 miles), about 100 kilometers north of the Flores island city of Maumere, where more than 80,000 people live, where the quake disrupted coronavirus vaccination.
Maumere resident Ulysses Tara said, "People were taking vaccines when the earthquake struck. They ran in panic."
"There were over 200 people ... and the (vaccination) event stopped because of the earthquake."
Thousands of people in Maumere sought safety on higher ground for fear of a tsunami.
"We will stay here ... because we are afraid of the aftershocks," said Hussery Tamarin.
'It was strong'
The Pacific Tsunami Warning Center said there was no longer a tsunami threat following earlier warnings that such waves were possible within 1,000 kilometers of the quake's epicenter.
Indonesian officials have also lifted a tsunami warning.
"I was checking my phone when the earthquake struck. I felt it for 30 seconds. It was strong," said Alwan, a resident of Butan in southeast Sulawesi.
Because of its position on the Pacific "Ring of Fire", Indonesia experiences frequent earthquakes and volcanic eruptions, an arc of intense seismic activity where tectonic plates collide that extends from Japan into Southeast Asia and the Pacific Basin.
Indonesia's history of deadly earthquakes includes a devastating 9.1-magnitude earthquake in 2004 that struck the coast of Sumatra and triggered a tsunami that killed 220,000 people across the region, including about 170,000 in Indonesia.
The Boxing Day tragedy was one of the deadliest natural disasters in recorded history.
In 2018, a powerful earthquake rocked the island of Lombok and several more tremors occurred over the next few weeks, killing more than 550 people on Holiday Island and neighboring Sumbawa.
Later that year, a 7.5-magnitude earthquake and subsequent tsunami struck Palu on the island of Sulawesi, killing or missing more than 4,300 people.
