Magnitude 6.1 earthquake strikes off Indonesia's East Nusa Tenggara
In short
A magnitude 6.1 earthquake struck 14 km southwest of Southwest Sumba Regency in Indonesia's East Nusa Tenggara province at 05:55 local time on 4 October, with a focal depth of 10 km, according to Indonesia's Meteorology, Climatology and Geophysics Agency. CLS reported there was no tsunami risk from the quake. The reports did not mention casualties or damage.
Why it matters
The quake was recorded at a shallow depth of 10 km in a province that is part of Indonesia's seismically active island chain, so local authorities and residents would typically watch for aftershocks and structural damage. The Chinese outlets covering it are state and financial news services, indicating the event drew attention mainly as a regional natural-hazard update rather than as a story with direct domestic consequences.
