6.1-Magnitude Earthquake Jolts Indonesia’s Sumatra Island

A powerful 6.1-magnitude earthquake struck off Indonesia’s Sumatra island, the USGS reported. The tremor hit waters near the quake-prone region along the Pacific Ring of Fire, where multiple tectonic plates converge. No immediate casualties or damage were reported. Sumatra lies on a major subduction zone along the Sunda-Java trench, making it highly vulnerable.
