204 after quakes

After the 8.8 earthquake there has been 204 after quakes. They are having after shocks but the USGS doesn’t show the small ones below 4.0 mag. I think it would clutter the maps up and I can’t zoom in any closer to see the small quakes between the larger quakes. Most of what’s going on is is 5.0 and above on the map. I heard a report that said the ground was constantly moving for a minute to ninety seconds every few minutes. I’ve noticed that the so called what would be after shocks are very spread out over 300 plus miles so I don’t know if you would call them separate quakes or after shocks and settling. If we had a quake here that was large like the 8.8 quake and had quakes in Los Angeles I think the USGS would call them separate quakes. So I don’t know how they are classifying these. No one has said anything on the news about this. Maybe I’ll have to send a note asking this question.
