Recently, an increase in seismic activity has been observed in areas considered to be of low seismicity. Such is the case of the state of Zacatecas, Mexico, where in recent years there has been a significant increase in seismic events. From 2015 to 2019, 16 earthquakes were registered in the state meanwhile that in 2020, the National Seismological Service (SSN) reported 116 seismic events. The main objective of this research is to determine if this increase in seismicity is due to the explosions caused by the mines that operate in the area, so the records corresponding to these tremors obtained from the ZAIG station of the SSN, located in the city of Zacatecas, are reviewed according to different criteria found in the literature to differentiate an earthquake from an explosion. Furthermore, these records are analyzed and compared with the records obtained from a vibration monitoring campaign carried out in a mine. According to the analysis of the results, it was determined that a large number of these earthquakes are the product of mining activity, this being the main cause of the increase in seismic activity in the region. Regarding the vibration levels of the records related to mining explosions defined in this research, these are compared with the international ISO standard, which defines different permissible levels according to different types of structures.
