Which risk increases in a caldera following resurgent dome formation?

💡 Explanation

The risk of phreatic eruptions increases because magma intrusion elevates groundwater temperatures causing increased steam pressure; therefore shallow steam explosions are more frequent rather than deeper magmatic ones.
