Which outcome results when a caldera experiences resurgence?

💡 Explanation

Resurgent calderas involve slow uplift due to magma accumulation; this positive feedback causes a central lava dome because plastic deformation of the partly crystallized magma creates surface extrusion, therefore a dome forms rather than a pyroclastic surge.
