Earthquake status: highly uncertain
This record is not from a real earthquake, because there is no officially confirmed earthquake that matches the user reports we have received of the reported event closely enough.
In most cases, this event likely reflects something else that caused the vibration, such as an explosion (typical of mining areas), a sonic boom, traffic, weather, or some other human or natural cause.
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.

Even if you don’t feel itEven though you were around, this is fun information you might like قد I can share! Original earthquake reports from users are of great interest to earthquake research, as they help in improving models related to ground vibrations and thus potential earthquake risks. You can use Fix your device’s position or drag the animated marker on the map to your location to indicate your location at the time of the earthquake (optional). Thank you so much!
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.
