An earthquake of magnitude 6.4 struck the Indonesia’s East Nusa Tenggara province on Thursday, the European-Mediterranean Seismological Centre (EMSC) said.

The Indonesian geological agency (BMKG) pegged the magnitude at 6.3 with no tsunami potential. The epicentre of the quake was onshore and at a depth of 25 kilometers (15.5 miles), located 15 kilometres from the capital of East Nusa Tenggara province, Kupang.

The quake was strongly felt in several cities in the province, but there were no immediate reports of damages.

Hotel guests at Aston Hotel in Kupang were panicking when the quake hit, said Samuel Malohana, a hotel employee. Around 100 guests left their room and gathered in front of the hotel.

“But now most of them have come back to their room and no damages at the hotel,” Samuel said.

Head of the Earthquake and Tsunami Center of BMKG, Daryono, said he received report of light damages at the office of Kupang’s regional head.

A shallow 6.0-magnitude earthquake hit near the Indonesian island of Sulawesi on Saturday, the United States Geological Survey said, with no damage or casualties immediately reported.

The tremor hit at 9:43 p.m. local time (1443 GMT) at a depth of 9.9 kilometres, according to the USGS.

Indonesia’s geophysics agency (BMKG) reported no immediate tsunami but warned of possible aftershocks. It initially reported a magnitude of 6.3.

“I was having a good sleep (when the earthquake jolted). I jumped out of bed immediately,” said Qamariah, a 41-year-old housewife in Central Sulawesi’s Malei village.

“It felt like being shaken as if rice was being sifted. It went up and then down. It was really strong because I lived close to the epicentre. It lasted for about 5 seconds,” she told AFP.

She said the power was out in her area so she could not see if there was damage.

“I am outside (my house) right now, with family and my neighbours,” she added.

Video obtained by AFP showed panicking people in Central Sulawesi’s Lambonga village gathered in groups outside of their homes as they sought safety in fear of aftershocks.

“As of now, there have been no reports of damage and casualties caused by the earthquake,” the Palu Search and Rescue Agency said in a statement.

“The residents of Balesang coastal village in Pabean, Donggala regency, have evacuated to higher ground, with the majority leaving their homes,” it added, referring to an area in Central Sulawesi.

Indonesia, a vast archipelago nation, experiences frequent earthquakes due to its position on the Pacific “Ring of Fire”, an arc of intense seismic activity where tectonic plates collide that stretches from Japan through Southeast Asia and across the Pacific basin.

A 6.2-magnitude quake that shook Sulawesi island in January 2021 killed more than 100 people and left thousands homeless.

In 2018, a 7.5-magnitude quake and subsequent tsunami in Palu on Sulawesi killed more than 2,200 people.

And in 2004, a 9.1-magnitude quake struck Aceh province, causing a tsunami and killing more than 170,000 people in Indonesia.

In November last year, a 5.6-magnitude quake hit the Southeast Asian nation’s Java island, killing 602 people.

Most of the victims of that earthquake were killed when buildings collapsed or in landslides triggered by the tremor.

A 6.1-magnitude earthquake struck off the country’s Sumatra island in April, shaking homes of panicked residents but causing no casualties or damage.

A powerful earthquake and two strong aftershocks rocked Indonesia’s resort island of Bali and other parts of the country early Tuesday, causing panic but no immediate reports of damage or casualties.

The U.S. Geological Survey said the quake had a preliminary magnitude of 7.1 and was centered in the Bali Sea 181 kilometers (112 miles) northeast of Gili Air, a tiny island near the coast of Lombok Island, next to Bali. It occurred at a depth of 513.5 kilometers (319 miles).

Indonesia’s Meteorology, Climatology and Geophysical Agency said there was no danger of a tsunami but warned of dangers from aftershocks. The agency put the quake’s preliminary magnitude at 7.4. Variations in early measurements are common.

The quake was followed by aftershocks of magnitude 5.4 and 5.6 that hit the Bali sea a few minutes later, just before dawn.

Many residents and tourists rushed out of their homes and hotels toward higher ground after reporting powerful shockwaves, but the situation returned to normal after they received text messages saying the quake had no potential to trigger a tsunami.

“I thought the walls were going to come down on the hotel,” an Australian tourist said on social media.

People in the neighboring provinces of East Java, Central Java, West Nusa Tenggara and East Nusa Tenggara also felt the tremors and panicked as houses and buildings swayed for several seconds.

Indonesia, a vast archipelago of 270 million people, is frequently struck by earthquakes, volcanic eruptions and tsunamis because of its location on the “Ring of Fire,” an arc of volcanoes and fault lines in the Pacific.

An earthquake in the hilly Karangasem in 2021 triggered landslides and cut off at least three villages, killing at least three people.

A magnitude 5.6 earthquake last year killed at least 331 people and injured nearly 600 in West Java’s Cianjur city. It was the deadliest in Indonesia since a 2018 quake and tsunami in Sulawesi killed about 4,340 people.

In 2004, an extremely powerful Indian Ocean quake set off a tsunami that killed more than 230,000 people in a dozen countries, most of them in Indonesia’s Aceh province.

A strong earthquake of 7.0 magnitude struck deep in the sea north of Bali and Lombok islands in Indonesia early on August 29, the European-Mediterranean Seismological Centre (EMSC) said, sending residents running out of buildings.

The quake’s epicentre was 203 km (126 miles) north of Mataram, Indonesia, and very deep at 516 km below the Earth’s surface, EMSC said.

Indonesian and U.S. geological agencies pegged the magnitude at 7.1, with no threat of a tsunami.

The quake was felt just before 4 a.m. (2000 GMT) across coastal areas in Bali and Lombok and was followed by two quakes of magnitude 6.1 and 6.5, according to the Indonesian geological agency.

Guests at Bali’s Mercure Kuta Bali ran out of their rooms after feeling the tremor for a few seconds, hotel manager Suadi told Reuters by phone.

“Several guests left their rooms but were still in the hotel area,” he said, adding they have since returned and there was no damage to the building.

There were no immediate reports of damage, Indonesian disaster agency BNPB said.

“The quake is deep so it should not be destructive,” BNPB spokesperson Abdul Muhari said.
