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.

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.
