At least three people have been killed and four injured after a powerful natural disaster struck near the popular tourist island of Bali.
If any reminder were needed of Indonesia's treacherous tectonics, a magnitude 6 quake struck off Java and Bali islands early on Thursday, killing three people in Java, damaging buildings and sparking panic.
BMKG head Dwikorita Karnawati told Agence France-Presse (AFP): "The quake didn't trigger any tsunami for sure".
Some residents briefly left their homes in the island's capital Denpasar, according to Reuters.
Its epicenter was near 40 km depth located 125 km to the east of the town of Kimbe, according to the USGS.
A 7.5 magnitude quake rocked Central Sulawesi province on September 28, triggering a tsunami and mudslides that killed a large number of people and displaced tens of thousands of others.
A tsunami warning system set up after 2004 failed to save lives in Sulawesi: it emerged too late that, due to neglect or vandalism, a network of 22 buoys connected to seabed sensors had been inoperable since 2012.
A massive relief effort is underway in Indonesia with British Red Cross, Action Aid DEC Indonesian Tsunami Appeal and Save the Children among the charities and non-for-profit organisations appealing the public to help raise money for the hundreds of thousands of people affected by the disaster.
"We send our condolences to those affected by the quake".
Rehabilitation and reconstruction will take until 2021, the government says.
In case of tsunami risk, attendees would be evacuated to a nearby building.
In Bali, residents describing strong tremors.
Indonesia's most populous Java island is next to the main tourist island of Bali, where the IMF-World Bank annual meetings are being held this week.
The news agency reported that some guests at hotels in Nusa Dua, south of Bali's main worldwide airport, briefly fled outside after a strong tremor. I immediately woke up and took my little kids out of the house.
"All my neighbours were also running", said the mother of two.
"Many summit participants woke up and asked questions, but we immediately sent out information to them that there had been an quake and the impact in Nusa Dua", he told AFP.
Indonesia has extended by a day its search for victims of a 7.5 magnitude quake and tsunami on Sulawesi island at the request of relatives of the many still missing.
