Identificación y correlación de los productos volcánicos con la sísmica del volcán el reventador durante el periodo octubre 2020- marzo 2021.

Abstract

El Reventador volcano is a young andesitic cone that is located between the provinces of Napo and Sucumbíos and is part of one of the many volcanic edifices that make up the Eastern Cordillera of the Ecuadorian volcanic arc. On November 3, 2002, it had a volcanic reactivation that is considered one of the largest eruptions recorded in Ecuador characterized by the emission of large volcanic products. Due to this, the present work has the purpose of carrying out the characterization of the volcanic activity on the surface of El Reventador volcano through the seismic signals recorded during the periods: October 28 - November 10, 2020, and December 1-8. from 2021, to track anomalies, eruptive precursors or monitor ongoing volcanic eruptions. For this, it was decided to work based on the data provided by the IG-EPN obtained from the LAV4 seismic station and through visual and infrared images provided by the REBECA camera. The period December 1-8, 2021 is characterized by presenting an effusive stage with a greater presence of lava flow events, little presence of eruptive column events and rolled blocks. On the other hand, the period between October 28 and November 10, 2020, is characterized by being an effusive period, with November 4 being one of the busiest days. It can be noted that the main volcanic products observed on the surface are lava flows, eruptive columns and on rolled blocks.
