Which process causes increased geyser activity near stratovolcanoes?

💡 Explanation

Magmatic heat transfer increases geyser activity because volcanic upwelling increases the geothermal gradient, leading to intense local heating and steam generation; therefore, more geysers bubble, rather than from snowmelt or aquifer pressure changes.
