According to EMSC there has been a ML4.2 earthquake in north Italy at 23:54 UTC on 24.01.2012. This earthquake appears to be located close to populated areas. I do not yet know if there has been any damage due to this earthquake. But if houses in the area are poorly built, there might be some light damage. It is hard to know for sure if this is an pre-earthquake or just one earthquake. There have already been some minor aftershocks already. But so far none of them have been larger then ML2.1.
I am going to update this blog post if anything more happens in Italy where this earthquake took place.
