How are satellite images used to predict volcanic eruption?

Answer 1

Satellites are used to monitor the changes in the shape of the mountains. Specifically this is done rather often on the big island of Hawaii to make sure that none of the two dormant volcanoes (Mauna Loa and Hualalai) are changing shape which would indicate magma movement into the upper Plumbing of the volcanoes. Often times the same type of radar imagery is used to reconstruct the changes throughout a volcanic eruption, this radar imagery service is also used on the Yellowstone Super Caldera. Examples of how this has been used can be seen on both the Hawaii Volcanoes Observatory website and Yellowstone Volcano Observatory website. (See related links).

Answer 3

Satellite images can be used to monitor changes in volcanic activity, such as increases in gas emissions, ground deformation, and thermal anomalies. By analyzing these changes over time, scientists can make predictions about potential volcanic eruptions and issue early warnings to mitigate the risks to nearby populations. Satellite data also allows for monitoring of remote and inaccessible volcanic regions, providing valuable insights into volcanic activity globally.
