JAKARTA, Indonesia (AP) - A strong earthquake struck off Indonesia's main island of Java, but there were no immediate reports of injuries or damage.
The U.S. Geological Survey said Monday morning's quake had a preliminary magnitude of 6.7.
It struck 318 kilometers (nearly 200 miles) off Java's southern coast, just 24 kilometers (15 miles) beneath the ocean floor, prompting local authorities to briefly issue a tsunami alert.
Indonesia is located on the Pacific "Ring of Fire," an arc of volcanos and fault lines encircling the Pacific Basin.
