An earthquake of magnitude 7.3 on the Richter scale struck 95 km north of Maumere, Indonesia on Tuesday, the United States Geological Survey (USGS) reported.

The USGS said the chance of casualties was low and warned that recent earthquakes in this area have caused secondary hazards such as tsunamis and landslides that might have contributed to losses.

The Pacific Tsunami Warning Center said “hazardous waves are possible for coasts located within 1,000 km (600 miles) of the quake epicentre”.

Hitting at an intermediate depth of 76 km beneath the epicentre near Maumere, East Nusa Tenggara at 11:20 AM local time, the earthquake struck the Flores Sea in southern Indonesia. 

The magnitude, epicenter, and depth of the quake might be revised within the next few hours as seismologists review data and refine their calculations, volcano discovery reported. 

The Indonesian seismological agency put the preliminary magnitude of Tuesday’s earthquake at 7.4, th a depth of 10 kilometers. The US Geological Survey (USGS) put the magnitude at 7.3, down from an earlier reading of 7.6.

France’s Réseau National de Surveillance Sismique (RéNaSS) listed the quake at magnitude 6.8.  Italy’s National Institute of Geophysics and Volcanology (INGV) reported a magnitude of 7.1, Geoscience Australia (GeoAu) at magnitude 7.3, the German Research Centre for Geosciences (GFZ) at magnitude 7.0, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 7.2.
