_{vp}of a looming eruption. This may play an important role in antidisaster measures because it is the parameter most determinate for evacuation. Continuous monitoring of M

_{vp}may also yield valuable information for judging the termination of an eruption because its stagnation indicates magma feeding disconnection from reservoir to shallower part. I believe that predictive volcanic early warnings with quantitative M

_{vp}can provide truly effective, practical information to residents and local governments potentially affected by active volcanoes.
