According to the Meteorology, Climatology, and Geophysics Agency (BMKG), the aftershocks occurred at 03:54 a.m., 04:12 a.m., and 04:37 a.m. local time. They did not potentially trigger tsunami.
In addition, the magnitude of those aftershocks was recorded at between 5.3 and 6.1 on the Richter scale. Their epicenter was located around 137 kilometers northwest of Jailolo at a depth of 10 kilometers.
Regarding this strong earthquake followed by repeated aftershocks, BMKG head Dwikorita Karnawati called on local residents to stay calm but vigilant to anticipate any unwanted eventuality.
"The aftershocks will likely occur in the aftermath of the 7.1-magnitude earthquake but local residents are expected to remain calm," the official said.
Located on the Ring of Fire, where several tectonic plates meet and cause frequent volcanic and seismic activities, Indonesia is susceptible to natural disasters, including earthquakes and volcanic eruptions. (Antara)
