JAKARTA (BNO NEWS) — A strong earthquake struck south of the Indonesian island of Java on Friday, seismologists said. There were conflicting reports on its magnitude, but no damage was immediately reported.

The earthquake was centered about 215 kilometers (135 miles) south of the city of Jember in East Java province. It also had a similar distance to the city of Denpasar, the capital city of Bali province. The earthquake struck around 1.43 a.m. local time at a depth of 53.9 kilometers (33.5 miles).

There were conflicting reports on the magnitude of the earthquake. The Badan Meteorologi Klimatologi Dan Geofisika (BMG), the country’s seismological center, reported a magnitude of 6.6. The United States Geological Survey (USGS), however, reported a magnitude of 5.7, which would make it a much smaller earthquake.

A seismologist at the USGS said the BMG may have had more data, and may have access to more earthquake sensors which led to a different magnitude. However, the USGS seismologist said they do not expect to change their magnitude.

Neither the BMG nor the Pacific Tsunami Warning Center issued a tsunami warning following the earthquake. There were no immediate reports of damage or casualties.
