Cave of death: Where is it located and why is it called so?

Costa Rica's Alajuela Province is home to the deadly 'Cave of Death,' where carbon dioxide continuously seeps, creating an asphyxiating environment. The cave is a mere six feet deep and emits up to 30 kilograms of CO2 every hour, forming a lethal trap for any living being venturing too close due to its geological alignment near the San Miguel fault.
