Yes, volcanoes can indeed threaten densely populated areas. When a volcano erupts, it can spew ash, lava, and toxic gases that can cause injuries and even death to those living nearby. Additionally, volcanic eruptions can trigger secondary hazards such as lahars (mudflows), pyroclastic flows, and landslides that can destroy homes and infrastructure in densely populated areas. Therefore, it is crucial for residents living near active volcanoes to be aware of the potential risks and have evacuation plans in place.
