Moderate tremor of magnitude 4.2 just reported 84 km southwest of Waingapu, Indonesia

An earthquake of magnitude 4.2 occurred around noon on Friday 6 August 2021 at 12:47 pm local time near Waingapu, East Nusa Tenggara, Indonesia, as reported by Indonesia's Meteorology, Climatology, and Geophysical Agency.
According to preliminary data, the quake was located at a shallow depth of 10 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 3.8 earthquake.
