Quake status: very uncertain
It is assumed that this recording did not come from an actual earthquake as there is no officially confirmed quake that exactly matches the user reports we received of the reported event.
In most cases, this event likely reflects something else that caused the tremors, such as B. an explosion (typical of mining areas), a sonic boom, traffic, weather, or some other human or natural cause.
The first report is below:
Although our monitoring service initially determined network activity typical of an earthquake, there was no confirmation from a national or international seismological agency. Because of this, it is highly unlikely that it was caused by an earthquake.
