Lecture 12: How Do We Monitor Volcanoes?

These flashcards provide key vocabulary terms related to volcanic monitoring and associated techniques.

Volcano Monitoring

Systematic analysis of data collected from a volcano to forecast eruptions.

Eruption Precursors

Events and signals such as seismic activity that indicate an impending eruption.

Seismic Activity

Earth vibrations caused by tectonic movements, which can signal volcanic activity.

Baseline Monitoring

Understanding the normal state of a volcano for comparison during monitoring.

InSAR (Interferometric Synthetic Aperture Radar)

A satellite-based technique that uses radar to detect ground deformation.

Tiltmeter

An instrument used to measure changes in the angle of a volcano's surface.

Gas Emissions

Gases such as CO2 and SO2 that provide insights into volcanic activity.

GPS (Global Positioning System)

A system used to monitor the movement and deformation of the Earth's surface in volcanic areas.

Seismic Signals

Seismic waves generated by magma movement that can indicate volcanic activity.

Thermal Imaging

A method to monitor temperature changes and detect heat associated with volcanic activity.
