The US Geological Survey uses a variety of technologies to monitor volcanic activity at the five monitoring stations and across the continental US, Alaska, Hawaii, and the Mariana Islands. Some of the technologies used include:
1. Seismometers: These instruments are used to detect and record ground movements caused by volcanic activity, such as earthquakes and tremors.
2. Infrasound detectors: These sensors can detect low-frequency sound waves produced by volcanic eruptions, allowing scientists to monitor activity even when visibility is limited.
3. Gas sensors: These devices are used to measure gases emitted by volcanoes, such as sulfur dioxide and carbon dioxide, which can provide valuable insights into the volcano's activity.
4. GPS monitoring: Global Positioning System (GPS) technology is used to track ground movements and deformation near volcanoes, providing valuable data on magma movement and potential eruption risks.
5. Thermal imaging: Infrared cameras are used to capture temperature changes near volcanic vents, which can help scientists monitor activity and identify potential areas of concern.
Overall, these technologies work together to provide a comprehensive picture of volcanic activity and help scientists monitor and predict potential eruptions.
