A powerful 6.0 magnitude earthquake struck the waters off East Nusa Tenggara province in eastern Indonesia on Tuesday, sending tremors across multiple coastal communities. Authorities confirmed the seismic event originated 67 kilometers northwest of North Central Timor at a depth of 31 kilometers, with officials quick to dismiss any tsunami threat.
Seismic activity rocks eastern Indonesian waters
A significant tectonic disturbance registered a magnitude of 6.0 on the Richter scale Tuesday afternoon, originating beneath the Flores Sea northwest of North Central Timor. The country's
Meteorology, Climatology, and Geophysics Agency (BMKG)
pinpointed the hypocenter at a depth of 31 kilometers, classifying it as a shallow-to-intermediate focus event. Situated within the volatile Pacific Ring of Fire, Indonesia experiences frequent geological disturbances due to the convergence of major tectonic plates beneath its sprawling archipelago.Tremors felt across multiple provincial centers
Ground motion extended throughout East Nusa Tenggara province, with varying degrees of intensity reported across the region. The coastal settlement of
Atambua
experienced the most pronounced effects, recording Modified Mercalli Intensity levels between III and IV, indicating noticeable shaking of suspended objects and stationary vehicles. Moderate vibrations reached Maumere
, while lighter perceptible motion affected residents in Kupang
, Kefamenanu
, Larantuka
, and Ende
. The widespread distribution of tremors reflects the substantial energy released during the underwater seismic shift.Authorities confirm absence of Tsunami risk
Official monitoring agencies rapidly assessed the oceanic disturbance and determined no tsunami generation potential, alleviating concerns among coastal populations. Initial field reports from local emergency management offices indicate an absence of structural collapses, injuries, or fatalities associated with the afternoon quake. Community safety protocols remained standard as geologists continue analyzing aftershock patterns. The region maintains heightened vigilance for subsequent seismic adjustments following significant magnitude events in these tectonically active maritime zones.
