A strong earthquake hit Indonesia's main island of Java on Saturday, injuring at least one person, sending people running out of buildings and shaking the same town devastated by a tremor last month that left more than 330 people dead.

The 5.7-magnitude quake struck on land at a depth of 112 kilometers (70 miles), with the epicenter located 18 kilometers southeast of the West Java city of Banjar, according to the United States Geological Survey.

Indonesia's meteorological agency, known as BMKG, gave a higher magnitude of 6.1 for the quake, which shook buildings in the capital Jakarta, according to an Agence France-Presse (AFP) journalist.

At least one person was injured and was taken to hospital, the country's national disaster mitigation chief Suharyanto, who like many Indonesians goes by one name, told broadcaster Metro TV.

There were no reports of other casualties or major damage.

The BMKG said the quake caused buildings to shake in the West Java town of Garut and it warned residents near the epicenter to beware of potential aftershocks.

But there was no threat of a tsunami, it said.

Budi Satria, the local rescue chief in Garut, said there appeared to be no significant damage.

"Some people ran outside when the earthquake happened but when it calmed down, they went back to their activities. Thank God, so far everything is safe," he told local broadcaster Kompas.

Indonesia experiences frequent seismic and volcanic activity due to its position on the Pacific "Ring of Fire," where tectonic plates collide.

Last month a shallow 5.6-magnitude quake hit the town of Cianjur in West Java, killing 331 people, injuring thousands and leaving tens of thousands homeless after it collapsed buildings and triggered landslides.

Many were found buried under rubble in the days following the quake with few successful rescues reported. One operation to free a six-year-old boy was described as a "miracle" by emergency workers.

Residents of Cianjur were shaken again by Saturday's quake and some roofs were lightly damaged, local military official Haryanto told Kompas.

"It made us feel like we were swaying. We could see hanging lamps swaying," he said.

Last month's disaster was the deadliest earthquake to hit the archipelago nation since a 2018 quake and resulting tsunami killed more than 4,000 people on the island of Sulawesi.

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