USGS Aftershock Forecast: What we think will happen next
According to our forecast, there is a 6% chance of one or more aftershocks that are larger than magnitude 5, which can be damaging, within the next week. There will likely be smaller aftershocks within the next week, with up to 32 magnitude 3 or higher aftershocks. Magnitude 3 and higher aftershocks are large enough to be felt nearby. The number of aftershocks will decrease over time, but a large aftershock can temporarily increase the number of aftershocks.
This forecast applies to the area where the earthquake and aftershocks are already occurring.
I just felt another either earthquake or aftershock I was in my bedroom and everything started to move the water bottles where shaking on my dresser it is 3:35 am now
We felt this vibration at around 3:30 A.M. in Penn Valley near Pilot Peak. I wouldn’t say it shook items on shelves or dressers, but it certainly shook a two-story house!
