JAKARTA, Indonesia (AP) — Indonesia’s geological agency has issued a tsunami warning after a quake with a preliminary magnitude of 7.5 struck waters off its eastern coast. It was not immediately clear if the quake caused any injuries or damage. The U.S. Geological Survey says the quake hit early Thursday and was centered 200 miles (327 kilometers) northeast of Manado, a town on Sulawesi island. It says it had a depth of about 20 miles (30 kilometers) beneath the ocean floor. The country’s local geological agency says the quake had the power to trigger a tsunami. Indonesia is prone to seismic upheaval due to its location on the so-called Pacific “Ring of Fire,” an arc of volcanos and fault lines encircling the Pacific Basin. —-Contact The Daily Reveille news staff at [email protected]
