How can you predict when a volcano is going to erupts?

Answer 1

when it starts getting warm and bubbling up and then about week later it would erupt.

Answer 2

Volcanic eruptions can be difficult to predict accurately, but scientists use various monitoring techniques to look for signs like increased seismic activity, ground deformation, and gas emissions to help forecast eruptions. It also depends on the type of volcano and its past behavior, with some showing clear patterns before an eruption while others may have more sudden events. Multiple factors are taken into consideration, and forecasting eruptions remains challenging despite advances in technology.
