For the Cenozoic Era, the epochs in chronological order, from the earliest to the most recent, are as follows: Paleocene , Eocene , Oligocene , Miocene , and Pliocene . The oldest of the geological eras is the Eoarchean, which began approximately four billion years ago. The majority of the fossil evidence that we have for primate evolution comes from the Cenozoic era —the current geological era, dating from 65 million year ago (MYA) to the present. The Cenozoic era is divided into a series of epochs.Earthquakes are complex phenomena that generate various forms of clusters that are highly correlated in the space and time domains. To study the dynamic properties of seismicity and estimate risk, the earthquake catalog needs to be separated into clustered and background events. Here, seismicity de-clustering is formulated as a binary many …
