Characterization of seismic swarms and their differences with seismic sequences in Venezuela

SEISMIC THREAT

Abstract

Venezuela is located in a tectonically active region, where it experiences seismic activity due to the interaction between the Caribbean and South American plates. One of the seismic activities that stand out are seismic swarms, which are a succession of earthquakes of similar magnitudes that occur in short periods and in localized areas, which differ significantly from conventional seismic sequences, characterized by a main earthquake of greater magnitude followed by aftershocks. This essay examines
the distinctive characteristics of seismic swarms compared to typical earthquake sequences in the tectonic context of Venezuela. Through the analysis of cases recorded in the state of Carabobo and other regions of the country, where the underlying geological and geophysical causes are addressed, including the movement of local faults, fluid migration and the interaction of the main tectonic structures. The natural and anthropogenic mechanisms that may influence these events in Venezuela, such as hydrothermal activity and human interventions, are also explored. In addition, the importance of seismological monitoring,
mapping of active faults, and community education to differentiate these phenomena and mitigate their impacts is highlighted. This study seeks to provide the geoscientific community with tools for a better understanding and management of seismic swarms in Venezuela, thus fostering greater resilience to seismic risks in the country.
