Abstract:

the seismogenic behavior of the el pilar fault close to the city of cumaná has been significantly improved by incorporating the 1629 earthquake in the seismic history of eastern venezuela. this destructive event was poorly known, documented and understood until very recently with the publication of the latest version of the seismologic catalog of venezuela in 1999. from documentary investigation of original primary sources or accounts, it has been possible to assess this earthquake and complete the seismic history of the region. the 1629 earthquake has been placed in relation to the el pilar fault, and its maximum intensity (io) and magnitude (ms) have been estimated at viii and 6.1-6.3, respectively. in addition, a preliminary return period has been derived between this earthquake and its successors in 1797 and 1929 (150 ± 18 years).
