Daryono, head of BMKG's Earthquake and Tsunami Center, said the main shock, measuring magnitude 4.0, occurred on Saturday at 11:47 p.m. local time at a depth of 7 kilometers in Sukabumi District.
"Based on waveforms recorded by the DBJI Darmaga and CBJI Citeko seismic sensors, the quake was tectonic, not volcanic," he explained.
The quake caused minor damage to five houses in Kabandungan sub-district, which is home to around 20 residents. No casualties or injuries were reported.
BMKG noted that the damage was due to a combination of the quake’s shallow hypocenter, soft soil conditions in the affected area, and building structures that did not meet earthquake-resistant standards.
A total of 39 aftershocks followed the main event, with magnitudes ranging from 1.9 to 3.8. Five of them were felt by the public.
Destructive quakes have occurred in the same area in the past. In March 2020, an earthquake in Kabandungan damaged hundreds of houses, while a December 2023 tremor damaged 61 homes. A similar incident in July 2000 also caused extensive damage in several sub-districts.
