How is seismic monitoring used to detect changes in Reventador’s activity?

Reventador Volcanic Activity in Realtime

Reventador, a stratovolcano located in the eastern Andes of Ecuador, has been exhibiting increased volcanic activity over the past few years. The volcano’s current phase of activity began in 2002, and since then, it has continued to erupt sporadically, with occasional large explosions and lava flows.

In recent years, monitoring of the volcano has become more sophisticated, with the implementation of real-time monitoring systems designed to detect changes in the volcano’s behavior. These systems include seismic monitoring, gas sampling, and satellite imagery.

Seismic monitoring is the most critical tool used to detect changes in Reventador’s activity. Seismographs are installed around the volcano, and they detect any tremors or vibrations caused by volcanic activity. These instruments can detect both small and large earthquakes, and the data they collect helps volcanologists determine the rate and type of activity occurring underground.

Another important indicator of Reventador’s activity is gas sampling. Volcanoes produce various gases, including sulfur dioxide, carbon dioxide, and water vapor. Monitoring these gases can provide clues about the origin and intensity of the volcanic activity. Samples of these gases are taken around the volcano, and their composition is analyzed to help determine the conditions that exist deep within the volcano.

Satellite imagery is also an essential tool used to monitor Reventador’s activity. Satellite sensors can detect changes in the temperature of the volcano’s surface, indicating where and when lava flows are occurring. They can also detect changes in the levels of sulfur dioxide emissions, providing early warning of major eruptions.

As of 2021, Reventador was in a state of elevated activity, with near-constant emissions of steam and ash, and frequent small explosions. The ongoing activity has produced a lava flow that has been flowing down the southeastern flank of the volcano since 2018. The lava-flow has already affected a large area, damaging infrastructure and agricultural land.

In conclusion, the real-time monitoring of Reventador’s activity is crucial in assessing the risk to human life and property from volcanic hazards. By using a combination of seismic monitoring, gas sampling, and satellite imagery, geologists can better understand the volcano’s behavior and forecast potential eruptions. With this information, appropriate measures can be taken to protect local populations and minimize the economic impact of volcanic activity.
