Magnitude 7.3 quake in Indonesia triggers tsunami alert

The quake was at a depth of 20km, EMSC said.

The quake triggered a tsunami warning, the country's Meteorological Department added.

Indonesia suffers frequent earthquakes, straddling the so-called "Pacific Ring of Fire," a seismically active zone where different plates of the earth's crust meet.

The Joint Australian Tsunami Warning Centre said there was no tsunami threat to the Australian mainland, islands or territories.
