NASA developed a new method of predicting volcanic eruptions using satellites

It's notoriously difficult to predict volcanic corruptions. There are often signs that a volcano is likely to erupt in the future, including an increase in seismic activity, changes in gas emissions, and sudden ground deformation but accurately predicting eruptions is hard. Part of the challenge is that no two volcanoes behave exactly the same way before they erupt and another part is because only a few of the active volcanoes around the world have monitoring systems in place.
