Earthquake status: highly uncertain

It is unlikely that this event was caused by a natural earthquake as it has not been confirmed by official seismic data. In most cases, it was another earthquake-like event of natural or artificial origin (eg, mine activity, eruptions, sonic booms, thunder, etc.).
Initial report below:

Although our monitoring service initially detected network activity typical of an earthquake, there was no confirmation from any national or international seismological agency. For this reason, it is highly unlikely that it was caused by an earthquake.

Compare earthquake data from different agencies

Tip: The more different agencies report the same earthquake, the more reliable the data and the more accurate one can derive the average value for magnitude, depth, etc. It usually takes a few hours for the seismic data to be accurately assessed and for the information to be of reliable accuracy. This often causes the volume and other data to correct up or down over and over again in the first few hours.
