A major 7.3-magnitude earthquake hit the remote Maluku islands in eastern Indonesia Sunday, sending panicked residents running into the streets, but no tsunami warning was issued.
The shallow quake struck about 165 kilometres (100 miles) south-southwest of the town of Ternate in North Maluku province at 6:28 pm (0928 GMT), according to the US Geological Survey.
"The earthquake was quite strong, sending residents to flee outside. They are panicking and many are now waiting on the roadside," said local disaster mitigation official Mansur, who like many Indonesians goes by one name.
Officials were assessing the situation but there were no immediate reports of casualties, he told AFP.
In the town of Labuha, one of the closest to the epicentre, panicked residents took to motorcycles in a bid to flee to higher ground, according to an AFP photographer in town when the earthquake hit.
Local disaster official Ihsan Subur told Metro TV that no damage or casualties had been reported there so far, but residents took to the streets and many evacuated to higher ground.
"Electricity went of during the earthquake, but now it's back to normal," Subur said, adding that at least seven big aftershocks were felt after the initial quake.
The province was also hit by a 6.9-magnitude tremor last week.
Indonesia experiences frequent seismic and volcanic activity due to its position on the Pacific "Ring of Fire", where tectonic plates collide.
Last year, a 7.5-magnitude quake and a subsequent tsunami in Palu on Sulawesi island killed more than 2,200 people, with another thousand declared missing.
On December 26, 2004, a devastating 9.1-magnitude earthquake struck off the coast of Sumatra and triggered a tsunami that killed 220,000 across the Indian Ocean region, including around 170,000 in Indonesia.
