JAKARTA — A strong undersea earthquake hit off of Indonesia's main island of Java on Sunday, but there were no immediate reports of injuries or damage, and no tsunami warning was issued.
The United States Geological Survey said the magnitude-6.0 quake that hit Sunday afternoon was centered 93 kilometres (58 miles) south of the East Java province town of Krajan Tambakrejo, at a depth of 59 kilometres (37 miles).
Indonesia is prone to earthquakes due to its location on the so-called Pacific "Ring of Fire."
A massive earthquake off Sumatra island in 2004 triggered a tsunami that killed 230,000 people in a dozen countries, mostly in Indonesia's Aceh province.
