Which risk increases in a rapidly emptying magma chamber?

💡 Explanation

Caldera collapse risk increases due to pressure loss causing gravitational forces exceeding the decreased support, therefore large-scale structural failure occurs, rather than lava changes or lahar formation which depend on additional environmental factors.

• Which consequence results when river sediment supply increases rapidly?
• Which outcome occurs when increased water content alters mantle viscosity above subduction zones?
• Which outcome typically results when rapid snowmelt saturates a pre-existing karst system above a municipal area?
• Which process causes the headwall of a cirque to steepen, leading to eventual enlargement?
• Which long-term outcome occurs when enhanced chemical weathering diminishes carbonate rock?
