We have not found any visible evidence of a surface blast and we can confirm it was not a result of a quarry blast. Local seismographs indicate a possible earthquake. However, we do not know for sure the cause of the event. Officials from the US Geological Survey will need to make that determination. We expect to receive communication from the Emergency Management staff when the cause of the event is determined.
Once that information is available, we will make it available here.
