This record is considered not to be from an actual earthquake, because there is no officially confirmed quake that matches the user reports we received of the reported event closely enough.
In most cases, this event likely reflects something else that caused shaking, such as an explosion (typical for mining areas), a sonic boom, traffic, weather, or some other human or natural cause.The initial report is below:
