Popis:	To highlight the importance of small earthquakes in seismic hazard, we present a study of the 11 May 2016, Mw 4.9, Tesistan earthquake. According to historical data from instrumental seismicity, this earthquake represents the largest event recorded near Guadalajara. Due to the close proximity of the event to the city, accelerations were considerable higher than those caused by historical severe earthquakes. From the analysis of regional seismicity, its occurrence: (i) shows a clear correlation with seismicity in the subduction zone and (ii) appears to be related to tectonic activity along a previously unmapped SE extension of the faults which form the northern wall of the Plan de Barrancas/Santa Rosa Graben, located to the northwest within the more regional Tepic-Zacoalco Rift. The analysis of the two strong ground motions recorded within the city reveals considerable site effects.
