<p id="sp0235">Whereas research in volcano geodesy seeks to push the boundaries of our knowledge of the physics of volcanoes, monitoring looks at changes in volcano behavior to predict when a volcanic crisis might develop. To be effective, geodetic monitoring must be done before, during, and after eruptions and must be integrated with other<span> </span><a title="Learn more about Monitoring Technique from ScienceDirect's AI-generated Topic Pages" href="https://www.sciencedirect.com/topics/earth-and-planetary-sciences/monitoring-technique" data-mce-href="https://www.sciencedirect.com/topics/earth-and-planetary-sciences/monitoring-technique">monitoring techniques</a><span>.
