KSLA News 12 staffers at the station on Fairfield Ave. heard and felt the blast as well.



The United States Geological Survey (USGS) says there was no seismic activity recorded in the area on Monday.



Mayeaux says he doesn't know why someone in the area of the debris field would not have reported seeing something. Based on the time frame and the fact that the radar scans every 6 minutes, he believes something had to have smoldered for 10 to 15 minutes in order for the debris to rise to the height that it did and remain on the radar for as long as it did.



And yet, Mayeaux says, "whatever happened that radar detected, it didn't elicit a response (from people in the area)."
