Using by active periods to volcanoes for predicting to big earthquakes as hazard is not a mystery...And,another informations for prediction of volcanic activity

Some questions about prediction to Big Earthquakes as hazard potential by knowed characteristics as "Activity Periods" of volcanoes are subject.

Firstly,I can express a important role for studies of this chapter...

As schematic;

Also,for good summary informations about activity prediction of volcanoes;

Note:A example for schematic expression at page is subject which based on activity period of Tungurahua Volcano.So,you will see that;

Thus,I carried-out a clear explanation against questions about how used based on active periods for big earthquakes by hazard potential of volcanoes

Thanks...
