TEMPO.CO, Jakarta - A 5.8 magnitude earthquake struck Southwest Maluku late Wednesday, October 1, 2025. Initial information from the Meteorology, Climatology, and Geophysics Agency (BMKG) said the tremor occurring at 10:49 p.m. local time had a magnitude of 6.1.
In an explanation shared by the Director of Earthquake and Tsunami Center at BMKG, Daryono, the earthquake's epicenter was offshore, 85 kilometers northeast of Southwest Maluku, at 176 kilometers depth.
"The earthquake was a moderate type triggered by deformity activity within the Banda Sea Plate," Daryono explained.
BMKG's modeling results indicated that no tsunami threat was caused by the tremor.
In Taikur region, the Southwest Maluku capital, the shaking was felt at III MMI, meaning many people felt it indoors, akin to a truck passing by.
BMKG revealed that they had not received any reports of damage caused by the earthquake. No aftershocks had been recorded.
