JAKARTA, Indonesia (AP) - A 7.3-magnitude quake hit Indonesian waters Saturday morning and has the potential to generate tsunami waves along nearby coasts, a monitoring agency said.
According to the U.S. Geological Survey, the quake hit 154 kilometers (96 miles) northwest of Kota Ternate at a depth of 47 kilometers (29 miles).
There are no immediate reports of casualties or damage.
The Pacific Tsunami Warning Center said the quake could cause hazardous tsunami waves within 300 kilometers (186 miles) of the epicenter along the nearby coasts of Indonesia and the southern Philippines. Waves could reach up to a meter (3.28 feet) or less, it said.
The nearest communities of Tabukan Tengah on North Sulawesi island could be at risk within an hour or so if a tsunami occurs, the agency said.
The world's largest archipelago, Indonesia is prone to earthquakes due to its location on the Pacific "Ring of Fire," an arc of volcanoes and fault lines in the Pacific Basin.
In 2004, a monster temblor off Aceh shores triggered a tsunami that killed 230,000 people in a dozen countries. Most of the deaths were in Aceh.
