Abstract. The Pátzcuaro–Acambay fault system (PAFS), located in the central part of the Trans-Mexican Volcanic Belt (TMVB), is delimited by an active transtensive deformation area associated with the oblique subduction zone between the Cocos and North American plates, with a convergence speed of 55 mm yr−1 at the latitude of the state of Michoacán, Mexico. Part of the oblique convergence is transferred to this fault system, where the slip rates range from 0.009 to 2.78 mm yr−1. This has caused historic earthquakes in Central Mexico, such as the Acambay quake (Ms=6.9) on 19 November 1912 with surface rupture, and another in Maravatío in 1979 with Ms=5.6. Also, paleoseismic analyses are showing Quaternary movements in some faults, with moderate to large magnitudes. Notably, this zone is seismically active, but lacks a dense local seismic network, and more importantly, its neotectonic movements have received very little attention. The present research encompasses three investigations carried out in the PAFS. First, the estimation of the maximum possible earthquake magnitudes, based on 316 fault lengths mapped on a 15 m digital elevation model, by means of three empirical relationships. In addition, the Hurst exponent Hw and its persistence, estimated for magnitudes Mw (spatial domain) and for 32 slip-rate data (time domain) by the wavelet variance analysis. Finally, the validity of the intrinsic definition of active fault proposed here. The average results for the estimation of the maximum and minimum magnitudes expected for this fault population are 5.5≤Mw≤7. Also, supported by the results of H at the spatial domain, this paper strongly suggests that the PAFS is classified in three different zones (western PAFS, central PAFS, and eastern PAFS) in terms of their roughness (Hw=0.7,Hw=0.5,Hw=0.8 respectively), showing different dynamics in seismotectonic activity and; the time domain, with a strong persistence Hw=0.949, suggests that the periodicities of slip rates are close in time (process with memory). The fractal capacity dimension (Db) is also estimated for the slip-rate series using the box-counting method. Inverse correlation between Db and low slip-rate concentration was observed. The resulting Db=1.86 is related to a lesser concentration of low slip-rates in the PAFS, suggesting that larger faults accommodate the strain more efficiently (length ≥3 km). Thus, in terms of fractal analysis, we can conclude that these 316 faults are seismically active, because they fulfill the intrinsic definition of active faults for the PAFS.

“…In order to characterize the persistence of the slip-rates distribution for faults in the MAFS, we construct the Devil's staircase of the cumulative slip-rates distribution organized from East to West, due the fact that the 1956-2016 instrumental locations in the central TMVB show that most of the microseismicity is concentrated in the eastern part of the MAFS, near to the Acambay Graben with a maximum depth of 15 km (Lacan et al, 2017). In order to obtain the fractal dimension for the slip-145 rates distribution (capacity dimension or box-dimension) for active faults, we use the Box counting 2D algorithm (Walsh and Watterson, 1993), to obtain the exponent D b in the relationship:…”

The Morelia-Acambay fault System (MAFS), located in the central part of the Trans-Mexican Volcanic Belt (TMVB) is delimited by an active transtensive deformation zone associated with the oblique subduction zone between the Cocos and North American plates, with a convergence velocity of 55 mm/yr at the latitude of the state of Michoacán, México. Part of the oblique convergence is transferred to the central TMVB, just in the MAFS zone, where the slip rates range from 0.009 to 2.78 mm/year. The occurrence of great earthquakes like the Acambay earthquake (M s = 6.7) on November 19, 1912 with a 5 surface rupture, and in Maravatío, 1979 with M b = 5.3 are located into the MAFS. The zone is seismically active but with large periods of recurrence, as revealed by the seismic sequence (2.5 < M w <3.0) occurred near the city of Morelia in October 2007, with focal mechanisms corresponding to normal faulting with left-lateral components. Moreover, there are some paleoseismicanalyses showing quaternary movements of some faults with magnitudes between 6.0 -7.1M w . The purpose of this work is to probe an intrinsic definition of Active Faults for the MAFS as well as the estimation of possible maximum earthquake 10 magnitudes, in order to understand the dynamic of seismic activity along the MAFS. For the new fault dimensions and using three empirical relationships, we found a maximum magnitude of M w = 7. Additionally, a slip-rates series were compiled and analyzed, the results show a temporal strong persistence behavior and a high value of fractal dimension (D b = 1.86) related with a less concentration of small slip-rates. In other words, there is not an excess of the deformation in the MAFS in a single or restricted range of scales, and furthermore, this represents a migration of the ruptures to larger scales (3  length  38 km). 15Copyright statement.
