According to the United States Geological Survey Agency (USGS), the epicenter of the earthquake was located 219km south of Raba city at a depth of 25km. There were no immediate tsunami warnings or reports of damage or casualties from the quake.

Indonesia is a disaster-prone archipelago that straddles the seismically active Pacific "Ring of Fire". It suffered its deadliest year in more than a decade in 2018 as a series of earthquakes and tsunamis killed more than 3,000 people.
