Monitoring Cascade Volcanoes
Active volcanoes are complex natural systems, and understanding a volcano's behaviors requires the attention of specialists from many science disciplines. It demands a combination of current knowledge about magma systems, tectonic plate motion, volcano deformation, earthquakes, gases, chemistry, volcano histories, processes, and hazards.
Monitoring Seismicity to Locate Earthquakes
Earthquake activity is the most consistent sign of volcanic unrest.
Deformation Monitoring Measures Inflation and Deflation of the Ground Surface
The land surface moves (deforms) as magma travels below the surface. Deformation measurements are made with several different tools and herald rising magma.
Volcanic Gas Monitoring Gives Clues about Magma Below
Monitoring the emission rates and chemical composition of volcanic gases can offer important clues to the inner workings of volcanoes.
Water Chemistry and Temperature Relate to Volcanic Activity
By monitoring the changes in chemistry and temperature of groundwater, surface water, and steam at a volcano over time, scientists can obtain useful information about changes in volcanic activity.
Automated Lahar Detection Systems
The Cascades Volcano Observatory uses Acoustic Flow Monitors (AFMs) to detect lahars originating on Cascades volcanoes.
CVO Scientists Develop Innovative Tools for Improved Volcano Monitoring
New instruments, software, and hardware developed by the USGS enable scientists to acquire, process, and interpret data quickly and effectively.
