Quads Today

It is an unusual day today, as I noticd when I was looking through my notes, that Quad Earthquakes are possible: I was not sure and when I decided to post, I checked and we already had 4 identical earthquakes. The problem with quads, is that the energy is split into 4 and therefore they are weak events. They are also not as often as doubles. So, time will tell if we are going to have more today, I dont think so but we will see. Here is the quads of the day anyway in Greece, and I think California is developping also. We will check it out later.
