La Falla de Bocono (FB), estructura mayor de la frontera transpresiva entre las placas Caribe y Suramerica,  presenta claras evidencias geomorficas diagnosticas de transcurrencia dextral cuaternaria en su sector mas  septentrional (Boc-e), ubicado a lo largo del margen noroeste de la depresion del rio Yaracuy. Dos excavaciones  paleosismicas, ejecutadas en las localidades de Yaritagua (El Salto) y Quigua, en proximidad a Barquisimeto y  San Felipe, respectivamente, en el ano 2005, no solo confirmaron su actividad tectonica durante el Holoceno,  sino que determinaron que la FB es responsable igualmente del sismo destructor del 26 de marzo de 1812, el  cual parece componerse de dos subeventos con epicentros macrosismicos: uno en el mar al ONO de Caracas; y  otro entre Barquisimeto y San Felipe, al pie de la sierra de Aroa, en el sector de la FB bajo estudio. Una grieta  abierta rellena en El Salto, cuya edad resulta mas joven que el ano 1770 DC, es la evidencia de este sismo. Por  su parte, FB en Quigua recurre con sismos Mw ≥ 7,0 cada 2.000-3.000 anos, desconociendose si esta es toda su  actividad sismica y haciendo presumir que la deformacion aqui debe estar distribuida en una amplia zona de  deformacion activa. Palabras clave: Falla de Bocono, paleosismicidad, sismicidad historica, sismo de Caracas de 1812, lluvia  cincuentenaria, valle del Yaracuy. PALEOSEISMIC ASSESSMENT OF THE SAN FELIPE SEGMENT OF THE  BOCONO FAULT (NORTHWESTERN VENEZUELA): RESPONSIBLE FOR THE  MARCH 26TH, 1812 EARTHQUAKE? The Bocono Fault (BF), a major tectonic feature of the current transpressive plate boundary zone between the  Caribbean and South America, exhibits a large number of Quaternary strike-slip landforms on its northernmost  sector (Boc-e), along the NW edge of the Yaracuy tectonic depression. Two paleoseismic trenches, excavated in  the vicinity of Yaritagua (El Salto) and Quigua, close to the cities of Barquisimeto and San Felipe respectively,  in 2005, not only confirmed the Holocene activity of the BF in this fault portion, but also allowed the ascription  to BF of the historical destructive earthquake of March 26th, 1812, which appears to have had two intensity  centers: one offshore meizoseismal area WNW of Caracas; and the other one between Barquisimeto and San  Felipe, at the foothills of the Aroa range, in the fault portion under study. An organic-rich filled open crack at El  Salto trench, whose 14C age is younger than 1770 AD, is the evidence to this earthquake. On the other hand, Mw  ≥ 7.0 earthquakes on the BF at Quigua recurs every 2000-3000 years. It is thought that present-day deformation  along and across Boc-e may be accommodated by a wider zone. Keywords : Bocono fault, paleoseismicity, historical seismicity, Caracas 1812 earthquake, fifty-year rain,  Yaracuy valley. Forma de citar: Audemard, F.A. 2016.
