Obtaining acceleration data for the Northeast of Brazil was not possible until recently. With the installation of RSISNE (Petrobras/UFRN/FUNPEC), this panorama has changed. It is now possible to acquire accelerometry data for the entire region. This work made use of these types of seismological records in order to obtain an equation that models how acceleration decays with distance, both in the vertical and horizontal components for the southern part of the Borborema Province. Secondly, it is also part of the objectives to establish relationships between acceleration and magnitude for the region. It was possible to establish an attenuation equation for the state of Pernambuco. While, for the state of Alagoas, it was possible to obtain a relationship between magnitude and acceleration for two new epicentral areas in the region.
