A strong earthquake of 6.0 magnitude has hit the coast of eastern Indonesia on Monday morning, according to the United States Geological Survey (USGS) seismologists.
USGS experts said the undersea quake struck at about 190 km north-east of Maumere, a holiday destination in Flores, at a depth of 522 km. The quake occurred at 9.13 am local time (9.1 3am Singapore time).
Indonesia's disaster agency said the officials were checking to see if the quake had any impact as there were no immediate reports of any casualties or damage. The authorities also said the quake did not trigger any tsunami alert.
Indonesia is positioned on the highly seismically active zone "Pacific Ring of Fire", which is known for collisions of tectonic plates, and hence it experiences frequent earthquakes.
