Kodi — Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) recorded a magnitude-3.5 earthquake in the sea 9 kilometres south of Kodi, Southwest Sumba, at 13:28:20 local time on Oct. 7, 2026. The tremor occurred at a depth of 19 kilometres and was felt at intensity II in Southwest Sumba.

The report describes a new aftershock in the Southwest Sumba earthquake sequence. The BMKG data listed by the Bali Provincial Regional Disaster Management Agency places the event offshore, south of Kodi, in East Nusa Tenggara.

For residents and visitors in Southwest Sumba, the report confirms that light shaking was felt in the regency after the earlier earthquake activity. Intensity II indicates weak shaking, and the listed report does not state that the event caused damage, injuries or a tsunami threat.
